“Healthier” Reverse Osmosis Systems

rob — Mon, 05 Sep 2011 16:47:48 +0000

The debate over the benefits and faults of Reverse Osmosis systems has been raging for years. For me, the issue is about creating better drinking water, but I understand the passion behind the debate because there is so much money at stake within the industry.

Our source water is getting more and more polluted and public funding for safe water continues to disappear. People are rightfully questioning the government position that our drinking water is safe. Drinking a glass of water from your tap today won’t make you sick overnight, but the cumulative effects of drinking contaminated tap water over time is very unhealthy.

My Meeting with a Large Reverse Osmosis Water Company

I had the good fortune to be contacted recently by a large retail chain of stores that sells RO water and RO equipment to the public. They found my blog and asked me to talk to them about Antioxidant Filters. I was impressed with the knowledge and experience of the people at the meeting. I was also impressed with their responsible attitude towards serving their customers.

The participants in the meeting were supporters of the benefits of water ionizers as they had all tried ionized water. However, the feedback on the electric water ionizers was that they were too expensive s, and they are not compatible with RO systems.

The people at the meeting asked to describe how and why the Antioxidant Filters perform so well with RO systems. They “got it” right away as soon as I explained how natural ionization works as opposed to electrolysis. It was simple to demonstrate the effectiveness of the Antioxidant Filter by testing the water with pH drops after it has passed through both the RO system and through the Antioxidant Filter.

It became instantly obvious to me at the meeting that there is a huge business opportunity available to those in the RO industry who understand that they can contact previous customers and upgrade their RO systems to provide “healthier” water.

Reverse Osmosis Systems: The Good

Reverse Osmosis systems were originally created for commercial purposes to remove salt from water and they are very effective in that regard. RO systems also remove many other contaminants from water, which means that they can be very beneficial in situations of unsafe water supply. In disaster situations where sanitation is compromised, RO systems can be life savers. For those that receive their drinking water from wells, lakes, or runoff, RO systems can remove harmful bacteria and other dangerous contaminants that may be present. Gone are the days when we can take clean water for granted, so RO systems definitely have a useful function in our world.

Reverse Osmosis Systems: The Bad

There are a number of arguments against RO systems, but the primary concerns are that the systems remove good stuff (essential minerals) from the water and that the systems make the water very acidic. Both concerns are real and important. There are other minor negatives to RO systems, but they are more of an inconvenience thing as opposed to real issues.

The RO System Rebuttal

The RO industry has been claiming for years that the body doesn’t absorb inorganic minerals found in water, so the argument that RO systems removed healthy minerals is redundant. After my meeting with the RO water company, I decided to do some research. The amount of information on the internet in support of RO systems being the best solution for drinking water is staggering. However, the information is completely biased and is not based upon facts, which shouldn’t come as a surprise to anyone.

Your body absorbs minerals such as Magnesium and Calcium from water

Contrary to what the Reverse Osmosis industry claims, your body does absorb minerals from water. I will limit my discussion for brevity reasons to a discussion of Magnesium and Calcium, two of the most important minerals in our bodies. Intuitively, you should know that our bodies can absorb minerals from water as our species has somehow managed to survive for thousands of years despite the fact that magnesium and calcium (which the body is unable to produce on its own) are not always available to everyone.

Magnesium:

The US government’s National Institute of Health says:

“Tap water can be a source of magnesium, but the amount varies according to the water supply. Water that naturally contains more minerals is described as “hard”. “Hard” water contains more magnesium than “soft” water”. The quote comes from http://ods.od.nih.gov/factsheets/magnesium.

Livestrong tells us:

In general, minerals already dissolved in water are more bio-available than solid forms, although many factors affect absorption within the small intestine, such as pH levels, health of the mucosal lining and the presence of other nutrients, as noted in the text, “Advanced Nutrition and Human Metabolism.” A French study published in a 2002 edition of the “European Journal of Clinical Nutrition” found that the absorption and bio-availability of magnesium in magnesium-rich mineral water was almost 60 percent in healthy male volunteers.

In comparison to absorption of minerals in water, supplemental forms are not absorbed as well. According to a review article published in a 2002 edition of the “Geriatric Times,” supplemental magnesium absorption ranges from about 30 to 41 percent and depends on age, intestinal health and type of magnesium supplement. You can check out the full article at:

Wikipedia informs us about the body’s ability to absorb Magnesium hydroxide. Wikipedia says “Magnesium hydroxide is an inorganic compound with the chemical formula Mg(OH)2……..Magnesium hydroxide is a common component of antacids and laxatives… all of magnesium hydroxide that does dissolve does dissociate. Since the dissociation of this small amount of dissolved magnesium hydroxide is complete, Magnesium hydroxide is considered a strong electrolyte.”

Calcium:

GoAskAlice, Columbia University’s Health Internet Service (http://www.goaskalice.columbia.edu/5403.html) tells us: “What we do know is that your body does absorb the calcium in hard water, and utilizes it the same way it would if it came from any other food source.”

I was surprised to learn from Livestrong (http://www.livestrong.com/article/440087-how-does-the-body-absorb-calcium/#ixzz1X0YyYKZX) that:

“Plant-derived foods that contain the chemicals oxalic acid or phytic acid inhibit calcium absorption by binding the mineral in your intestines. Bound calcium cannot be absorbed. Foods that contain a high concentration of oxalic acid include spinach, collards, radishes, beet greens, amaranth, carrots, lettuce and sweet potatoes. Concentrated amounts of phytic acid are found in nuts, seeds, beans and whole-grain products”.
I also learned that your body can’t absorb Calcium without the presence of Magnesium.

Summary:

Like so many things we read on the internet or hear from sales people with a vested interest, the stories are not necessarily based upon facts.

RO systems do remove healthy minerals from water along with a myriad of unhealthy contaminants. I have spoken with many individuals that have suffered from calcium leaching due to drinking RO water. At the same time, I have also spoken to many people who have consumed RO water for many years that are perfectly healthy if they take Calcium and Magnesium supplements.

There appears to be a symbiotic relationship between RO systems and Antioxidant Filters that use Magnesium as their primary ionizing medium. RO systems are superior purifiers that will extend the filter life of the Antioxidant Filters. The balanced minerals found in Antioxidant Filters replace the minerals that are removed by RO systems and add other essential minerals that the body absorbs. The Antioxidant Filters also provide the wonderful health benefits of alkaline and antioxidant water that are not possible with the use of a Reverse Osmosis system on its own.

It looks like the RO guys that brought me in to the meeting are on to something very powerful. I applaud them for their forward thinking and initiative

Hard Water Scale – Answers and Solutions

Hard Water Scale – Answers and Solutions

rob — Mon, 28 Jun 2010 18:26:46 +0000

Hard water is not considered harmful to your health, but it can cause ugly stains from scale build up in sinks, tubs, and elsewhere if left unchecked. People notice the stains, but they are generally unaware of the significant hidden costs of the scale build until it is too late.

Scale is formed when minerals (usually calcium) are precipitated out of water. The scaling process accelerates dramatically when the temperature of the water increases or when water travels across the electrically charged plates in a water ionizer.

The hidden costs of hard water scaling:

While hard water scale strains are annoying, the more significant problem is the cost associated with scale buildup. Hot water tanks create scale at a rapid rate as the heat facilitates the precipitation of calcium out of the water. The scale forms on the two heating elements in the tank. As the scale builds up, more and more energy is required to heat up the water in the tank. Nobody thinks about the additional cost of heating their hot water because it is out of sight and out of mind. However, the energy wasted can amount to several hundred dollars per year. Additional costs from scaling show up in the form of shortened lifespans of heat producing appliances such as dishwashers, washing machines, kettles, and water ionizers. Additional costs show up in the form or replacing taps and sinks. The greatest cost of all, can come in the form of having to replace water lines if excessive scaling is not kept in check.

What is hard water and how is it measured?

Hard water is water with a high mineral content. The primary components of water hardness are the cations (Ca 2+) and Magnesium (Mg 2+), with calcium playing the major role. Calcium usually enters the water as either calcium carbonate (CaCO_3,) in the form of limestone and chalk, or calcium sulfate (CaSO₄). The predominant source of magnesium is dolomite (CaMg(CO₃)₂). Less significant contributors to water hardness are other dissolved compounds such as the anions of bicarbonates ( HCO₃⁻) and sulfates (SO2−4).

Water hardness is measured in parts per million (ppm) or grains per gallon (gpg). In the USA, 1 gpg = 17.1 ppm. In Canada, 1 gpg = 14.2 pmp. I prefer parts per million as the measure is consistent in both countries. There is no absolute definition of levels of water hardness. However, it is generally accepted that the following categories of water hardness exist:

Soft: Below 17 ppm [or 0-1 American gpg]
Medium: 17.1 – 60 ppm [or 1 - American 3 gpg]
Medium Hard: 61 – 120 ppm [or 3 - 7 American gpg]
Hard: 121 – 200 ppm [or 7 – 11 American gpg]
Very Hard: Over 200 ppm [or over 11 American gpg

It is recommended that anyone that has hard or very hard water take measures to reduce the level of hardness, particularly from the hot water lines. My focus is on water ionizers, and they definitely require some form of assistance to remove calcium from hard water. The plates of a water ionizer will quickly get covered with scale in hard water which will render the ionization process useless.

Reducing hard water for an entire house:

The traditional method of reducing water hardness was to use a salt based water softener. The keep the discussion really short and simple, the system captures calcium and magnesium with beads, and then washes out the beads with salt each day. The state of California has banned the sale of salt based water softeners. I expect that we will see the ban extended to other jurisdictions over time, because the high sodium content of softened water is absorbed by your skin during showers or baths. When people use water softeners, it is recommended that the soft water not be used for drinking water, as the level of sodium typically exceeds maximum acceptable levels and definitely exceeds recommending intake levels of sodium by a wide margin. We are now seeing growth in salt free water softeners, which are much healthier for your skin.

You can also eliminate water hardness with a distillation system or a reverse osmosis machine. However the process is very slow and wastes a great deal of water. As such, a reverse osmosis or distillation system is typically reserved for purifying drinking water. I don’t care for either system if any other alternative is possible because the systems strip all of the minerals required by your body out of the water.

Reducing hardness in your drinking water:

As I stated earlier, hard water won’t hurt you. However, it wrecks havoc with you drinking water line and tap, as scale builds up. Homes that use salt based water softeners should always have a bypass before the water softener so that you never drink water that has passed through the softener. If you use a salt-free water softener, you don’t need a bypass because the water is safe to drink and it will not scale up your water line or taps. If you are thinking about installing a water softener, make sure it is a salt-free system. The salt-free systems typically pay for themselves in about two years, so they are an excellent investment.

If you already use use a salt based water softener and you don’t have a a bypass system under your kitchen sink, you will need a RO system to eliminate the sodium from your drinking water supply. If you are stuck with a RO system under your sink, you will need to replenish the minerals in your drinking water with mineral drops, or by installing an in-line remineralizing filter in order to provide your body with the minerals it requires.

What to do about hard water if you want to purchase a water ionizer?

Scaling from hard water has disastrous results for water ionizers. Therefore, you have to deal with hard water, or don’t bother purchasing a water ionizer at all. Since water ionizers are so import to your health, find a solution that works the best for you.

If you don’t have a water softener and you need one, make sure you purchase a salt-free system. The system will prevent scaling and it will allow your water ionizer to work efficiently.

If you already have a salt based water softener and you want to purchase a water ionizer, you have a number of options:

A) Bypass the water softener and install an inline magnet just before the water ionizer – one time cost of about $95

B) Bypass the water softener and install an inline phosphate filter before the water ionizer – cost $40 every six months for a phosphate filter

C) Install a RO system under your sink and add an inline remineralization filter – cost about $400 + $40 per remineralization filter

D) Replace your salt based water softener with a salt-free water softener – cost about $1,000

You can also combine A) and B) or you can add A) and B) to D). It all depends upon the level of hardness. These options all add to your costs, but nothing is more important to your health.
