Does Seawater Desalination a Necessary Evil?


Oceans contain 96.5 percent of the total water available on earth. When you combine this fact with the rapid depletion of groundwater resources, it’s very plain to see that the sea is the resource that the world will have to rely upon for all the potable water needs. Advancement in seawater desalination has made the use of this resource realistic at all levels. Desalination systems or watermakers convert brackish seawater into pure, drinkable water. Majority of these systems use Reverse Osmosis to do their job because of its unmatched efficiency. Not only does an RO system remove saline content, it also eliminates all other impurities associated with seawater.

Reverse Osmosis traps impurities and contaminants in a semi-permeable membrane through which water is pushed at a certain pressure. This phenomenon is also used for industrial and home water purification as it eliminates unwanted salts, chemicals, organisms, bacteria, viruses, metallic content and a lot more. The conversion of seawater into pure water requires a substantial amount of energy and resources but considering the scarcity of alternative water resources, it is still a beneficial proposition. The enhancement of reverse-osmosis based desalination technology is making the process more cost-effective as we go along.

The improvement of desalination watermaker components is also making the conversion more energy-efficient. The best example is the increasingly wide accessibility to watermakers for cruisers. Just a few years back, only a few boat owners could afford a fully-functional watermaker and the rest relied upon tanks and other traditional methods. The authorities worldwide are also working consistently to increase the efficiency while reducing costs and energy consumptions of desalination systems because they consider seawater as the most reliable resource for ending water related worries.

Not only for ships and yachts, Seawater desalination has been successful in ensuring pure water for other areas as well. For a lot of parts of developed and developing nations, desalination has made drinkable water a reality. The most active contributors to global desalination are Saudi Arabia with 17 percent of global output, United Arab Emirates with 13.4 percent, and the United States with 13 percent. Owing to the ongoing advancement, the United States is poised to become even more progressive in this field. As far as environmental considerations and energy consumption go, the latest Desalination Reverse Osmosis hardware makes the process very favorable. The future of desalination systems promises to be even more energy and cost-effective.


Is it time when my water softener needs regeneration? How does it actually work?


Every water softener will need regeneration at some point. To understand why, it is important to know how a softener works. A softener is deployed to do what its name clearly suggests; to soften water. Hard water, as we know brings plenty of disadvantages along such as lack of proper cleaning and washing, build-up in appliances and unhealthy skin & hair. A water softener works by separating hardness causing minerals such as calcium and magnesium from water. The outcome of its operation is soft water that forms adequate leather and is safe for your skin.

The process that makes water softening possible is the ion exchange phenomenon. Softeners contain resin or granular substance typically sodium. When these resins are made to bump hard water, they release sodium or potassium ions while trapping magnesium and calcium ions. Quite naturally, these resins are bound to contain excess of hardness causing minerals with the passage of time and exchange cycles. When that point comes, these resins are required to regenerate in order to be able to facilitate the exchange process effectively. This process is known as regeneration.

For regeneration, the softener pushes brine water towards the resins which separates magnesium and calcium from the resins and releases them out. The frequency of this phenomenon depends on the usage. Typically, it is not a process that the user has to trigger or initiate. The regeneration should start and end automatically. The component responsible for recognizing the need of regeneration and executing it is the control valve. The control valve can be programmed to trigger regeneration in a couple of methods.

One of them is a time-based method which involves an automatic regeneration which happens after an interval preset into the system. This time interval is generally fixed by a water filtration professional. Depending upon your usage patterns, water quality, size of the tank, an expert will set the regeneration frequency. Another method involves sensing of the amount of water processed through the sensor. Instead of time, this method triggers the regeneration after a fixed amount of water has been processed. The frequency in this case will vary with each cycle due to changing requirements. For some cases, this method might prove to be a more optimal choice.

If your water starts showing signs of hardness through your appliances and the leather formation, then it might have something to do with the regeneration process. In such situations, it is wise to check if your softener’s brine tank seems to be empty. You may also check for any blockage in your drainage as it can cause an obstruction while the softener tries to regenerate. Frequent power outages can also interfere with the time settings of the softener. You can isolate this cause by making a reset and observing the water quality thereafter. If these measures don’t yield a good outcome, then it is a good idea to get in touch with a water filtration expert or your machine’s manufacturer without wasting time.

Does your water smell bad? Maybe its time to look at the condition of your water softener


Almost all water supplies have some level of hardness depending upon surrounding conditions. Certain factors like neighboring industries, the state of soil and more can thrust unwanted components such as excessive carbonate, calcium and magnesium. It is the above-limit presence of these minerals which makes water hard.

The hardness of water has a lot of disadvantages. The first thing you’ll notice if your water supply is hard is the lack of sufficient leather formation when you use soaps or detergents with water for cleaning or washing purposes. When that happens, it becomes quite tough for you to carry out a wide range of cleaning tasks. The hardness will limit the ability of your washing machine to wash your clothes properly.

Another detriment of water hardness is for the appliances. Things like coffee maker and water heater will start developing debris, rings and some might even go to the extent of being blocked. That’s not all; hard water is not good for your skin and hair as well. In summation, you’ve got plenty of reasons to ensure that your water doesn’t stay hard. That’s why several homes install a cost-friendly solution to this problem called the water softener. Based on ion exchange technique, a softener involves an interchange of calcium and magnesium ions with sodium chloride. This process results in removal of hardness of water.

With the passage of time, some softeners start smelling bad. There can be several reasons for this. The first one is the exhaustion of the activated carbon present inside the ion exchange system. After the activated carbon is used up, it becomes very likely to breed a lot of bacteria and hence the smell. This is the reason why it is advised to do proper maintenance and replacement of necessary parts like filters. A thorough cleaning of the system and replacement of filters will eliminate the unwanted smell quite easily.

Another reason for that odor can be sulfur bacteria infestation. Sulfur bacteria have a high probability to infest sodium which is a key component of a typical ion exchange softener. The sulfur bacteria produces hydrogen sulfide overtime which is the gas responsible for all that smell. The solution to this is to call a water filter repair expert. They will take the necessary steps to eliminate bacteria and consequently the smell.

Certain water supplies contain excessive amount of sulfur, iron or hydrogen sulfide. These contents react with the softener apparatus and again result in a gas which produces an unpleasant smell. It is due to such reasons that it becomes essential to get your water supply tested before installing a system.

If you know of these impurities in advance, you can then have the appropriate pre-treatment or filtration parts which can get rid of such substances and make water pure or fit for further treatment before it is consumed. Nevertheless, even if you catch it late, you can bring in those extra pre-filters to fix your water concerns but the process can be costlier and inconvenient.

Home Water Filtration Systems Which Can Give Your Home Clean and Pure Water


Whatever culture you’re from, whatever lifestyle you lead, there is one thing which is constant and that is the need of pure water for your home. Water in an untreated or contaminated form is nothing short of a deadly disease carrier. Depending upon the kind of activities in the surrounding environment, the soil conditions and a lot of other uncontrollable factors, your water supply may be carrying a combination of chemicals, particles, organisms and even radiations which are not good for your health. The need for pure water was recognized way back and for several years now, there have been countless methods implemented for making water healthy and safe for consumption. Basic measure such as boiling to highly sophisticated machines, there is serious technology in place for water purification.

Let’s understand some of these techniques and see how each helps eradicate impurities from water.

Distillation: The most tried and tested method which has been going on for generations. Works by boiling the water and sending the vapors to a condenser which converts the vapor back into its original form with added purity. By doing this, the water loses a lot of its impurities right at the boiling stage. Where this method fails a little is the removal of certain stubborn chemicals. Some harmful chemical types don’t get eliminated by boiling alone.

Sediment Purification: If your water supply contains a lot of particles, then this method will work really well for you. It involves pushing of raw water through a sediment filter. The filter blocks particles and releases consumable water. While Sediment Purification is the best for killing particles but it is far from the best when it comes to eliminating chemicals and other minute impurities. When merged with another advanced purification designed to kill chemicals, it forms a comprehensive filtration system.

Carbon Adsorption: What sediment purification is unable to achieve, carbon adsorption takes care of. It involves the use of activated carbon which not only blocks large organics and particles but also traps the minute ones. The type of material used for these filters is decided based upon the unique purification needs of the water supply.

Ultra Violet Systems: Ultra violet rays are absolutely ruthless when it comes to eliminating germs and organics from water. A typical UV purification system either kills these unwanted contaminants or makes them completely harmless. The effectiveness of UV is undoubtedly excellent while eradicating organics, but it proves to be quite inadequate while removing particles from water.

Candle or Ceramic Purification: Another one of the traditional methods, candle purification holds back unwanted chemical content while releasing pure water. While it is highly cost-effective, ceramic purification is not your pick if you’re looking for utmost purity out of your system.

Reverse Osmosis: Reverse Osmosis is the most comprehensive, reliable and effective technology for water purification. What makes it so powerful is its ability to remove the widest range of impurities which include bacteria, virus, chemicals, radiations, particles, organisms and a lot more. This extensiveness is not offered by any other technique. When you combine an RO with other systems mentioned above, it delivers the level of purity that you will get from bottled water. Not only for residential purposes, this technology is considered to be the most effective even for commercial applications requiring high water purity.

What’s best water to drink? Is it reverse osmosis? Distilled? Ionized? Deep artesian well? or High mountain spring?


1- All are far superior to tap water.
2- Any water is better than no water.
3- It depends on what you’re looking for.

Besides simple access to drinkable water (an increasingly scarce commodity
worldwide), purity is the concern of water consumers. However, avoidance of contaminants is only half of the water issue: Improved health is the other.

As specialists in cancer prevention education for over 30 years, we at are constantly teaching people about the health benefits of
water. Quality hydration is one of the most important aspects of any
wellness program — whether for sports performance, optimal weight and
energy, or disease protection.

water softener

Our bodies are about 70% water, and we should be consuming at least half
our weight in ounces of pure water daily. Water transports nutrients
required for cell metabolism and removes waste substances that can damage
cells. It helps flush the eliminatory organs, preventing chemicals and
other toxins from accumulating in the body. Most of us are chronically
dehydrated because we drink too little water, consume dehydrating
beverages like coffee and soda, eat foods with no water content (i.e., few
fruits and vegetables), and/or lose liters of water daily through vigorous
exercise and normal body functions.

The quality of the water we drink is as important as the quantity of
water. Other than purity, there are three important properties of
healthful water: oxygenation / antioxidant potential, micro-clustering,
and alkalinity.

When water has been ionized, it is more alkaline, contains a higher oxygen
to hydrogen ratio than normal H2O, has extra electrons (a healthful
negative charge), and contains millions of natural antioxidant bubbles
called hydroxyl ions, which are free radical scavengers. Negative ORP
(Oxidation-Reduction Potential), characteristic of ionized water and fresh
uncooked foods, is beneficial to our body in that it decreases oxidation
and aging. Positive ORP, found in tap water, some bottled waters, and
cooked foods, increases oxidation.

Water molecules come in clusters rather than single molecules. Tap water
has very large clusters of molecules, whereas research has demonstrated
that the ideal size for water to get into our cells is under six clustered
molecules. Because the ionization process breaks the electrical bonding of
water molecules and restructures the water down to smaller clusters, the
resulting micro-clustered water is more easily absorbed into the cells,
thereby providing superior cellular hydration and detoxification.

Water is the most crucial factor in establishing and maintaining proper
acid-alkaline balance. pH (Potential Hydrogen) is a measure of relative
acidity or alkalinity, with 0 at the extreme acid end of the scale and 14
at the extreme alkaline end. The blood stream seeks to maintain a
consistent pH balance of 7.3 or 7.4, but poor quality diet, stress,
environmental toxins, and medications can cause our metabolic pH to become
too acidic. Because disease thrives in acidosis, drinking alkaline water
is the fastest way to positively impact health and eradicate inflammation
caused by excess acidity. High pH water (about 9.5) can alkalinize the
body at the cellular level and help the blood stream maintain its
appropriate pH. This, in turn, helps to increase energy, improve sleep,
reduce pain, eliminate acid reflux, normalize blood pressure and weight,
and resist disease.

Some fascinating Japanese research with 40,000 chickens illustrates the
health benefits of alkaline water. All received the same feed, but one
group was given regular ground water and the other group mineral alkaline
water. After one month, the mortality rate of the chicks on the alkaline
water was one-eighth the rate of the regular water group. After two months
on the alkaline water, diabetic animals demonstrated a 34% reduction in
blood sugar levels as compared with the regular water group; also noted
were drops in cholesterol values. Most impressive were the cancer results.
After only 15 days, the number, size and weight of cancerous tumors were
50% lower in the alkaline water group than they were in the regular water
group (McMillan FD, J Am Vet Med Assoc 1999; 215(7):992-9).

High alkalinity and high oxygen are two factors of particular interest to
us in our cancer work. Research has shown that the best way to prevent
cancer or to keep it from recurring is to provide an inhospitable
environment in which cancer cells cannot grow. Nobel prize winner Dr. Otto
Warburg showed that cancer thrives in a low oxygen, highly acidic
environment. Oxygen destroys cancer cells as well as bacterial and viral
invaders. Alkaline ionized water helps increase the level of oxygen in the
body by enabling more oxygen to attach to hemoglobin binding sites in the

Ionized mineral alkaline water acts as a conductor of electrochemical
activity from cell to cell. It can help the body resist disease and slow
aging by increasing intracellular hydration, replenishing essential
minerals, and protecting cells from free radical damage. However, not
everyone wants to purchase an ionizer. For convenience and accessibility,
bottled water is still in high demand. But which brand is best?

There are at least eight factors to take into account before answering
that question, including the water’s source, purity, pH, oxygenation,
hydration, bottle, taste, and cost. Many brands score high in some areas
but low in others. However, very few, if any, score high in all areas.

Do I Require a Water Softener and Will It Take Some Important Minerals Away?

Water hardness is associated with almost all kinds of supply due to a large number of reasons including the surrounding soil, pipe material and more. Technically, water is considered to be hard if it contains more than acceptable levels of calcium, magnesium, carbonate, etc.

How does hard water affect you or your home?

  • The hardness of water makes it less likely to produce leather when used with soaps or detergents. This will affect all kinds of washing and cleaning applications. If your supply distributes hard water, then it’s quite possible that you’ll notice that your clothes do not come out as clean as they should from the washing machine. Your dishes will also show signs of residue. This problem will reflect across almost everything you clean or wash with water
  • Another thing that hard water causes is skin and hair problems. It will not allow a thorough shampooing of skin or hair.
  • Hard water is also quite hostile for your appliances. It can create unwanted rubbles or build-ups in your water heater, coffee maker and can also go to the extent of blocking your pipes.

With the help of a water softener, you can fix the above problems very smoothly. A water softener removes excess minerals including magnesium and calcium and delivers softened water for all cleaning and washing applications.

Let’s understand how a water softener goes about its job. A standard softener works on the ion exchange technique. It causes an exchange of calcium & magnesium ions with sodium chloride.

A typical softener arrangement will have a couple of tanks; one containing beads called resin tank and the other containing salts called the brine tank. The raw water goes through the resin tank in which the mineral ions bond with the negatively charged beads. The beads then absorb the minerals and release sodium. This way, the water sheds calcium and magnesium and attains a softer form.

water softener

The purpose of the brine tank is to regenerate the functionality of the system because with the passage of softening cycles, the beads lose their effectiveness. This happens as magnesium and calcium eventually consume all the sodium in the tank. The brine tank re-activates the softening process by supplying the required amount of sodium.

Now, if your water will take in more sodium, you might be curious if that will be safe for consumption. Well, you don’t have to worry at all because all softeners are designed to keep the sodium level very very low.

You might also be concerned if removing minerals from your water deprive you of some essential nutrients. The answer to that is an absolute “no”, because the minerals found in water supply are not in a digestible form. As per medical experts, the right source for consuming magnesium and calcium are foods that are rich in these minerals. Their form found in water is highly inorganic and tough to digest.

Going behind the scenes of a Reverse Osmosis System


The much hyped phenomenon called Reverse Osmosis is quickly becoming a part of every home. RO is the reason that many of us get to consume safe water. While everybody know that this a surefire technique for water purification, but only some would know exactly what goes into purifying water so effectively with a reverse osmosis system.

Starting with the technique; first, let us understand that this is not a super complicated process that you will get a migraine while trying to comprehend. In fact, it is pretty straightforward and has been in use for quite a few years now.So, Reverse Osmosis was developed after analyzing the effects of the Osmosis principle.


In Osmosis, a low concentrated solution or a less salty one (for ease of understanding) is converted into a high concentration solution by passing it through a semi-permeable membrane. For purification, the objectives are exactly the opposite and that is why the scientist turned the process around to see what comes out.

Well what came out was a great purification technique. When tried in the lab, the reverse process turned salty solution into a less salty one. The core technology has remained the same but has seen a substantial amount of evolution in terms of components which facilitate the process.

You must have figured by now that something called “a semi-permeable membrane” is a very important part.

However, that is not the only thing that makes it successful. There are several other components which make a reverse osmosis system efficient, easy to use, durable and much more. Let us now explore everything that works backstage:

Water Supply Line Valve: This is where the system gets the raw water from. One end is connected with the supply and the other goes into the system.

Pr-treatment mechanism: Very often, the raw water supply needs to be per-filtered in order to be all-set to be treated further by RO. Generally in form of a filter, the sediment pre-filter removes heavier particles and impurities from the raw water, then the carbon pre-filter remove, chlorine, organics, bacteria, improving taste odor and clarity of the raw water

Semi-Permeable Membrane: The heart of the system; the membrane does most of the purification. It absorbs impurities and releases pure, drinkable water for consumption.

Polishing Post-Treatment: The membrane is not where the filtration stops. To further eliminate taste and odors, water goes through another carbon polishing post-filter. This stage is determined according to the unique filtration needs of a supply

Check Valve Assembly: The purpose of this part is to prevent treated water from running back towards the membrane. It is generally placed at the outlet of the membrane
Flow Restrictor: Uneven flow can interfere with the quality of water purification. This is where flow restrictor helps; it allows upkeep of just the right volume required for membrane to process optimal amount of water


Automatic Shut-off-valve: This valve stops further purification once it senses that the storage tank is full to prevent the RO system from wasting water.

Faucet/Tap: This is the medium that finally delivers water treated from various stages. It is required to be easily operated and durable.

Drain Saddle Connection: The separated impure water runs to an outlet or drain through this component.

Storage Tank: Depending upon the needs of your home or office, RO systems come in various storage capacity configurations.

With the above information, you can surely make an intelligent decision while buying an RO system for your home. Understanding the purpose of each component will give you a fair idea of what exactly you would need to ensure highly pure water from your supply.
