What is the definition of water?
Scientifically, water is defined as the composition of only H2O (two atoms of hydrogen and one atom of oxygen).

Why is water important to human body?
It is the basis for human life. It controls and regulates the digestive system, detoxification/elimination system and body temperature. It also helps maintain a healthy body and a healthy body weight..

Is water from the tap drinkable?
In most countries, water is treated before being piped to consumers and some people actually drink water straight from the tap. This implies that the water is 'safe' or to use a more technical term, 'potable'.

In Malaysia, although I don't know of anyone who drinks water straight from the tap, almost all of us swallow small amount of tap water each time we brush our teeth. Since we don't suffer immediate sickness or health problems, we can conclude that the mains water which is being supplied to our home is 'safe' or 'potable'.

Is our tap water healthy?
Many people that I have spoken with in Malaysia are not sure about this. Thus we need to consider that 'safe' is not always 'healthy'. To illustrate this point, an analogy I often use is this: If you were in an undeveloped country, would you choose to eat at their local stalls or trust an international fast food chain?

Almost all of us would agree that the fast food is the 'safe' choice. On the other hand, would you consider eating fast food daily even though it's 'safe'? Hopefully not! Thus it is easy to see that 'safe' is not necessarily equivalent to healthy.

What about dangerous drugs in water?
It is a fact that pharmaceutical drugs – including tranquilisers, heart medication and sex hormones – get past modern wastewater treatment processes and are finding their way into drinking water in countries all around the world.

There may be no immediate health effects from consuming minute traces of drugs in the water, but is certainly there is a potentially harmful cumulative effect on health. The reason is quite simple: drugs are purposely designed to have specific effects on the human body in relatively small doses.

Is this really a threat in Malaysia?
I would say that it is a threat in every country where people take medication. The human body works the same; the methods of water treatment are the same; the disposal of unused medicines is the same. Why, then, would we expect different results?

Is there any testing being done on this issue?
To date, there are no mandated requirements for testing for the presence of pharmaceutical drugs in drinking water. In fact, there are no established safety limits for drugs in water. However, there is active discussion taking place in the wake of the findings of the five-month long Associated Press (AP) investigative report that was published in March of this year. I am sure you won't want your child drinking sex hormones or any of the other drugs being found in drinking water all over the world.

What about other types of contamination?
Drugs are the latest reported threat in water, but they are by no means the only threat. According to the Earth Day Network on CNN, 14 million people in the US now regularly drink water contaminated with carcinogenic herbicides.

In New Zealand, the Southland was singled out as having elevated levels of nitrates in groundwater. High levels of nitrates are associated with the so-called 'Blue-baby syndrome'. Drinking water containing nitrates is particularly harmful to infants, pregnant women and their fetuses.

Water treatment systems are helpless in removing many contaminants; can they actually add to the danger?
The AP report pointed out that a powerful disinfection compound known as chlorine is used to kill bacteria and viruses. However, the same report pointed out that chlorine can actually make some of the pharmaceutical contaminants even more dangerous. Chlorine reacts with organic matter which naturally occurs in reservoirs, rivers and streams used as the source of drinking water. This reaction creates disinfection by-products (DBPs) such as trihalomethanes.

DBPs are carcinogenic, which means cancer causing. Studies have shown that people who drink chlorinated water have a higher risk of certain types of cancer than people who don't drink chlorinated water. This is one of the reasons that DBP levels are closely regulated in many countries.

According to an environmental working group study, published in 2005, tap water in the US is contaminated with "44 pollutants that are residues of water treatment, storage and distribution, including chemical by-products of water disinfection, are served to 178,679,000 people in 41 states in the US

Do we really need 'good' water for good health?
The human body is nearly 70% water! If we don't drink 'good' water, how can we expect to have good health?

What about minerals? Do we need or want minerals in our drinking water?
Even though there are differing opinions. I am personally very sure that the answer is: NO.

First, most minerals in water are inorganic (from dissolved stones) and cannot be easily assimilated or used by our body. Second, even if our bodies could use them, there is no home water treatment system in the world that can differentiate between so-called 'good' minerals, such as calcium or magnesium, and 'bad' minerals such as nitrates, arsenic, lead, etc.

Nature's way of providing the entire earth with water is through rain or snow that contains no minerals. It stands to reason that our drinking water should be the same - mineral free.

Third, a glass of milk contains more calcium than 500 litres of average tap water. To obtain the same amount of calcium as from a glass of milk, you would need to consume at least 500 litres of typical tap water daily, which is an impossible feat.

How do you choose?
We must first differentiate between a water filtration system and a water purification system. A filtration system basically removes some particles and maybe smell and colour in water. However, a properly designed purification system does much, much more.

Whether it is filtration, UV light, distillation or purification system, the function of a water system is to clean and improve the water. So choose a system that will not only improve the taste of water or its colour but also remove the other contaminants commonly found in water.

Find out what technology it uses, what contaminants it can remove, what the after-sales service is like, how many years the company has been in the business, whether it has been accredited by an independent body. These are all valid concerns.

What is the best water system?
One of the best ways to produce highly pure water, which is just H2O is by using the Reverse Osmosis (R.O.) process.


What is the R.O. process?
It was originally developed in the early 1950's. It took many years to perfect this technology which resembles nature's own unique purification process.

Water is forced (by pressure) through a special membrane and purified at the molecular level. The incredibly small pores (or openings) of the membrane allows water molecules to pass through. Virtually all other contaminants, including the traces of drugs, cannot pass through the membrane.

What is the membrane?
The semi-permeable R.O. membrane is very similar in function to the membrane of a living cell wall. It is selective about what it allows to pass through and what it prevents from passing. The membrane rejects virtually all contaminants (even microscopic) whilst allowing H2O molecules (water) to pass through.

In very high quality R.O. systems, the effective porosity of the membrane is 0.0001 microns in diameter – that's about 500,000 times smaller than the diameter of your hair!

Below is a chart showing you the size of various water contaminants:

Hair / Dust 20 - 80 microns
Bacteria 0.1 - 3 micron
Virus 0.02 - 0.1 micron
Chemicals As small as .0001 micron
Dissolved Heavy Metals / salts As small as .0001 micron


Where and how else is R.O. being used?
R.O. is being used by many major multi-national corporations, especially those involved in the food and beverage industry such as bottled water and soft drinks, and industries where a supply of pure water is critical such as pharmaceutical and microchip companies. Haemodialysis treatment centres around the World uses R.O. Desalination plants worldwide, including Newater in Singapore, also use R.O. technology to convert sea water into drinking water.

How does R.O. water differ from other types of filtered water?
R.O. can remove particles and dissolved substances as small as 0.0001 micron. It virtually removes all contaminants such as biological pollutants, organic chemicals, inorganic minerals, disinfection by-products, etc. Essentially, you are getting the purest water available.

Since all R.O. systems use membranes, they're all equally good, right?
Wrong, you get what you pay for. There are many different grades of R.O. membrane. In addition, since filters and membranes are hidden from sight, you can't verify their claims for performance. Other components in the unit may also contribute to secondary contamination. That's where international certification comes in.

If water is too pure, will our health be affected if we consume pure water in the long run?
Definitely not! That's like saying food can be too pure, or air too pure to breathe! Instead, pure water will help cleanse your body and strengthen your system.

Is R.O. alkaline water? Our body needs alkaline!
While it is true that about 80% of the food we consume should be alkaline in nature, this is not the case with water. Water is not nutrition. Pure water is often naturally acidic. A rain drop is formed with ph of around 5.7. Thus, nature provides us with water that is naturally lower in pH.

There is a rising concern that R.O. water with low PH is unhealthy. Is this true?
The pH of pure water has nothing to do with the healthiness of water. When you ingest pure water, your body changes the pH to its required level at that time so there is no need to worry. Remember, orange juice is 10,000 times more acidic than R.O. water, yet it is perfectly healthy!


Where can I purchase a unit of Elken Bio Pure?
Elken Bio Pure is available at over 100 stockists in Malaysia and in six others countries – Singapore, Indonesia, Thailand, Brunei, Hong Kong and India.

By using the Bio Pure System, will it tremendously increase my water bill?
Absolutely not. In virtually all cases, it will add literally less than $1 USD per month to the average water bill.

How much water will be purged out ('rinse' water) in order to produce 1 liter of pure water?
To produce 1 litre of water, 3 litres of water are rinsed out. Although it seems like a large portion of water usage versus the water produced, the chart below shows the cost of rinsed out water daily/monthly. If you wish, you may also collect the rinsed out water for other washing purposes.

1 Day: 10 liters 30 liters *1,000 liters = RM0.57
30 liters = RM0.017
1 month: 300 liters 900 liters 900 liters = RM0.52


What differentiates Elken Bio Pure from the rest?
There are numerous treatment methods being used today, including activated carbon, ultraviolet light and R.O. membrane purification technology.

What are other technologies used out there and how do they compare to Elken Bio Pure's technology?
To produce 1 litre of water, 3 litres of water are rinsed out. Although it seems like a large portion of water usage versus the water produced, the chart below shows the cost of rinsed out water daily/monthly. If you wish, you may also collect the rinsed out water for other washing purposes.

Activated carbon combined with ultraviolet light is effective in removing organic chemicals such as pesticides & herbicides and biological pollutants such as bacteria & viruses but ineffective in removing inorganic contaminants such as total dissolved solids (like nitrates and arsenic) & heavy metals such as lead and cadmium.

The R.O. membrane in combination with activated carbon removes virtually all contaminants including inorganic minerals, chlorine and disinfected by-products.

Elken Bio Pure uses both activated carbon and R.O. membrane.

What other advantages?
The company provides after sales service teams that are ISO certified with more than 150 technicians, 150 service vehicles and 14 service centres with 24-hour turnaround service.
