What is Organic and Inorganic Chemicals

Firstly, we need to know what is Organic and Inorganic :

Basically Organic Chemistry is :

       - Matter in its various forms that contain carbon atoms in its chemical structure.

 

And Inorganic Chemistry is :

1.       Matter in its various forms that do not contain any carbon atoms in its chemical structure which consists of  salts or mineral salts.

2.       Naturally found or man-made (Fertilizers )

Dietary elements (commonly known as dietary minerals or mineral nutrients) are the chemical elements required by living organisms :

The 19 are :

The 4 basic organic elements

1.       Carbon

2.       Hydrogen

3.       Nitrogen

4.       Oxygen

The 7 major dietary elements

1.       Calcium

2.       Phosphorous

3.       Potassium

4.       Sulfur

5.       Sodium

6.       Chlorine

7.       Magnesium

8 Important "trace" or minor dietary elements, necessary for Human survival

1.       Iron

2.       Cobalt

3.       Copper

4.       Zinc

5.       Molybdenum

6.       Iodine

7.       Bromine

8.       Selenium

Organic Minerals - these are minerals from a living source i.e. fruits, vegetables, grains and eggs. These minerals can be absorbed (assimilated) by our body and form part of our body nutrient requirements. Minerals found in our food supply are known as "organic".

Inorganic Minerals - are those minerals from mother earth i.e. magnesium, calcium, iron and potassium etc. Minerals found in drinking water are known as "inorganic".

Unfortunately for the human body, it cannot absorb most minerals directly from water because they are in inorganic forms. Humans cannot convert inorganic minerals into organic minerals.

Only plants can absorb inorganic minerals and transform them into organic minerals to nourish our body. Furthermore, the minerals content in water is very minimal (or in trace amounts).

Ultra-Pure Water - Know the Science Behind It

Every day around the world, tens of millions of gallons of the cleanest water possible are created, water so clean that it is regarded as an industrial solvent, absolutely central to high-tech manufacturing but not safe for human consumption. Welcome to the world of Ultra-Pure Water ( UPW ).

Four examples where UPW applications :

• Water for cleaning the surfaces of semiconductor wafers and liquid crystal panels, which must have no minute foreign particles.
• Water for steam generators for the power generating turbines needed for the stable operation of power stations.
• Refined water and injection water for medical care and pharmaceutical industries, where safety is vital in any situation. 
• Blank water for micro-analysis in analytical chemistry, directly linked with the analysis level.

For the semi-conductor industry, the water washes clean of the solvents and debris generated from an etching process which cuts up chips on a semi-conductor disc. The water has absolutely nothing in it except water molecules - not only no specks of dirt or random ions, no salts or minerals, it can’t have any particles of any kind, not even minuscule parts of cells or viruses.

Basically the source water is RO water or equivalent more cleaner process.  Ultra-pure water requires 12 filtration steps beyond RO. (For those of a technical bent, the final filter in making UPW has pores that are 20 nanometers wide, Electrical resistivity 18MΩ•cm / Electrical conductivity 0.056 µS/cm, Particulate count (>0.2μm) 20/mL or less, Viable bacteria 0.2/mL or less. )

Water is a good cleaner because it is a good solvent--the so-called “universal solvent,” excellent at dissolving all kinds of things. UPW is particularly “hungry,” in solvent terms, because it starts so clean. That’s why it is so valuable for washing semiconductors.

It’s also why it’s not safe to drink. A single glass of UPW wouldn’t hurt you. But even that one glass of water would instantly start leeching valuable minerals back out of your body.

In fact, super-clean water tastes flat, heavy, and bitter. The opposite of what we like. The appealing freshness in water comes not just from it’s temperature and its appearance, but from a sprinkling of salts and minerals that give it a crisp taste.


Conclusion

You can't and should never think of drinking Ultra-Pure Water for daily or health benefits.  

Reverse Osmosis Water - What is it, what you need to know and Understand

We have heard of Reverse Osmosis or simply RO Water which to us in Singapore is the PUB ( Public Utilities Board ) NeWater. It is a product of very clean filtered water that it's source can come from very concentrated ( Seawater / brine water ) or from treated effluent water ( wastewater ). Let us go thru in detail what is this water all about.

Reverse Osmosis is a revolutionary water treatment technology that was first developed in the late 1950's as a method of desalinating sea water. Also known as Ultra-Filtration, reverse osmosis is the process by which water molecules are forced through a 0.0001 micron semi-permeable membrane through the use of water pressure. This membrane allows only microscopic water molecules to pass through, filtering out almost everything else including 90-99% of all contaminants in the water, including inorganic minerals. In water filter comparison tests, reverse osmosis systems always beat standard carbon filters in the removal of harmful contaminants in tap or well water.

 
Today this technology has earned its rightful status as the most convenient and thorough method to produce contaminant free clean water. It is used by many water and soda bottling plants and by many industries that require ultra-refined water in manufacturing. Reverse osmosis has also made its way into the residential sector and has become a popular under-the-counter water filtration system for many families. However there are some competitors in the water filtration market that argue against the use of reverse osmosis for drinking water and have spread many outrageous rumors against it online in the hopes of discrediting the technology. 

However, some critics say that this water is unnatural and is not good for human consumption. Is this “Pure Water” free of inorganic minerals good for human health?

The Q and A on these Myths will cover some of the issues and claims brought up against reverse osmosis technology by those critics.

Myth #1 - Reverse osmosis purified water is unhealthy to drink.
Truth: Reverse osmosis water is very clean and healthy to drink.

Reverse osmosis (RO) has been called unnatural water because of its purity. Detractors claim it is man-made and unhealthy and should only be used for industrial applications and not for human consumption.

Worst, as PUB has developed NEWater from treated wastewater, we are drinking “Pang Sai” water ! Adding on to the criticism, they say that RO water is too pure and clean to be good because such perfectly clean mineral-free water does not exist naturally on earth. However this type of water does exist, it's called RAIN.

Rainwater is water that has been stripped of all minerals and is often one of the purest and cleanest water on earth. People have been drinking rainwater for thousands of years without any negative health effects. Only recently has rainwater been polluted by the industrial age and man's pollution of the skies. In the absence of heavy natural or man-made air pollution, rainwater can be very pure and safe to drink. While rain water may absorb and pick-up some substances as it falls through the atmosphere, minerals are not one of them. Thus people have been drinking mineral-free water for thousands of years, which is very normal when you consider that nothing is more natural than mother nature's life giving rain.

With the scientific research that has been done over the past 40 years on reverse osmosis water, none has ever documented any negative health effects from people drinking RO water. In fact, RO technology has also been extensively tested in the past by the US military and is approved for and highly used throughout the military as drinking water. Even commercial ships are now equipped with RO filters for directly taking seawater for their drinking / process water needs.

Myth #2 - Reverse osmosis filters remove healthy minerals from water.
Truth: Reverse osmosis filters remove inorganic, unhealthy minerals from water.

RO systems do remove minerals from tap water. However, we humans get the vast majority of our minerals from the foods we eat, not from drinking water. For example, 1 glass of orange juice has the same amount of minerals as 30 gallons of tap water. You would also get more minerals from 1 vitamin tablet than you will from drinking a month's supply of tap water.

Tap water contains only inorganic minerals which cannot be properly absorbed by our bodies. Human beings need organic minerals which are only available from living organisms like plants and vegetables and are easily absorbed by our systems. According to the WQA & WHO (Water Quality Association - World Health Organization) we get the vast majority of our minerals from food not from drinking water. The inorganic minerals found in water has little to no benefits to people and in fact can be very bad to our health.

It is estimated that over a 70-year lifespan, a person drinking tap or mineral water will be ingesting about 90 to 140 kilograms of rock that their body cannot use. While most of these microscopic rock minerals will be eliminated from our bodies regularly, some will be stored in our tissues becoming toxic over time. The primary culprits are calcium salts and over time they can cause gallstones, kidney stones, bone & joint calcification, arthritis, and hardening and blocking our arteries. The presence of other hard metal minerals is suspected to cause other degenerative diseases as well including eye glaucoma, cataracts, hearing loss, emphysema, diabetes, obesity and cancer.

Reverse osmosis water purification simply delivers the cleanest, purest drinking water on the market. What about distilled water you say? Distillation systems are comparable in contaminant removal, however since many synthetic chemicals such as herbicides, pesticides and chlorine solutions have boiling points lower than water, these chemicals will vaporize and can be carried over into the product water container actually making the collected purified water even more concentrated in those particular chemicals. Distilled water systems also require very high energy costs to operate and are very slow in producing water.

Reverse osmosis is also the only purification system that can remove the majority of dangerous Pharmaceuticals & Drugs from our drinking water. According to AP news reports provided by this USA Today article & Fox News report - "Reverse Osmosis removes virtually all pharmaceutical contaminants".

Reverse osmosis removes many contaminants that countertop and faucet carbon filters cannot including viruses, bacteria, pesticides, arsenic, fluoride, drugs, cryptosporidium, mercury, nitrates, microbes, heavy metals, all radioactive materials, and many more.

The lack of minerals in your water should not keep you up at night. The increasing amounts of chemicals, drugs and carcinogenic/radioactive minerals potentially found in tap water should!

Myth #3 - Reverse osmosis leaches minerals from the body.
Truth: Reverse osmosis water cannot leach minerals from the human body.

Water is called the universal solvent as it always "wants" to have substances dissolved in it. The purer the water, the more aggressive it becomes in attacking things that can dissolve. This doesn't hurt the human body, because our physiology quickly obtains homeostasis using saliva, stomach fluids, etc. to equilibrate all bodily fluids.

Reverse Osmosis technology was created in the 1970s and has been scientifically tested in every conceivable way since then. There has never been any documented evidence to prove that reverse osmosis treated water can leach minerals from the human body. The US Navy for example has used water with less than 3 parts per million total dissolved solids (TDS) for more than 40 years, according to a 1993 Water Quality Association (WQA) report, which also said the Army's field personnel drinks RO water.

In early July, 2008, the Brighton Standard Blade, a Colorado newspaper contacted the EPA at their readers request to find out if RO water leaches minerals. The EPA spokeswoman said that their organization does not support this idea. The WQA also rejects the idea that RO water can leach minerals in a 1993 report titled,'Consumption of Low TDS Water'. Their extensive research presented evidence that suggests water with low amounts of total dissolved solids (TDS), such as distilled water and reverse osmosis treated water has no ill effects on humans.

Water Technology Magazine also disagrees with this myth giving a list of sources that dispels the false water propaganda.

Myth #4 - Reverse osmosis filtration produces very acidic water with low pH
Truth: Reverse osmosis has little affect on water pH values.

Reverse osmosis purification may or may not reduce pH levels as it removes unhealthy inorganic minerals from tap water. Water pH is very complicated and pH levels vary constantly depending on a host of factors which can only be measured by water chemists and PhDs. The truth is, water pH levels will automatically change when it is ingested and comes into contact with the food in your stomach. Even on an empty stomach, your stomach acid alone is already several times more acidic than RO water (pH 6-8) with a pH level of 2.

The human body regulates pH levels constantly to find balance and equilibrium. Therefore under normal conditions it will always maintain a neutral 7.4 pH balance. Even eating very acidic foods (very low pH) only alters the body's pH by a very tiny amount and only for a short time. The healthy body is very robust and it will restore homeostatic pH fairly quickly and easily. Soft drinks and sports drinks typically have a pH level of 2.5, orange juice has a 3 pH and coffee has a 4 pH level and we drink these beverages all the time without problems.

As long as you eat a well balanced diet which includes vegetables and fruits, you can pretty much drink whatever you want without ever worrying about your pH balance.

Myth #5 - Reverse osmosis wastes a lot of water.
Truth: Reverse osmosis uses some water to deliver quality and longevity.

For every gallon of clean water produced by a RO system, an average of 4 gallons of rinse or flushing water is used and discarded. This water is constantly used by the system to clean the membrane and allows the filter to work effectively and last for many years. 

Reverse osmosis rinse / flushing water is the equivalent of an extra 3 to 4 toilet flushes a day. You actually waste more water each day when you wash your dishes or clothes than from a RO system. You will probably pay an extra 2-4% more on your bills also. Just do take note : the rinse / flushing water from RO systems is actually pretty clean and similar to tap water in purity levels. It can be channeled for use in gardens watering plants or stored and used for other household applications.

Water that flows down the sink is not wasted and can be recycled into clean water.  The truth is, there is no "new" water on this planet. All water is old water that has been recycled continuously for millions of years. We are actually drinking the same water that the dinosaurs drank, recycled obviously by Mother Nature.

Conclusion

Reverse osmosis water filters can remove thousands of organic, inorganic and chemical pollutants from tap water. The water is very clean and pure, protecting our health from chlorine, fluoride, arsenic and even pharmaceutical drugs. Reverse Osmosis systems are typically 4 to 5 stage systems that in addition to the RO membrane, also include a sediment filter and several carbon filter stages. This makes them much better at removing contaminants when compared to countertop, faucet and pitcher filters which use only 1 simple carbon filter. Reverse osmosis systems remove the heavy metals, radioactive materials, bacteria, viruses, fluoride, mercury, arsenic, nitrates, chemicals and drugs that standard countertop carbon filters cannot remove.
