Master Water Filters Malaysia
A water filter’s basic function is to remove impurities and contaminants from water via chemically, physically or biologically. Filters make use of sieving, adsorption, ion exchanges, biological metabolite transfer and other processes to remove the contaminants. A filter can remove particles much smaller than the holes through which the water passes. The type of filters used will depend on its purpose, whether the filtration is for drinking water, for aquariums, ponds, irrigation purposes or for swimming pools.
Why is water filtration important
When water is filtered, harmful contaminants are removed and the end result is having a much healthier body. The body becomes less prone to disease and infection and this leads to overall improved health & well-being.
The removal of foul smelling elements from drinking water, including chlorine and bacterial contaminants will give us better tasting water.
The removal of health hazardous chemicals like lead will give us water that is safe to use. A good water filtration system is able to remove chlorine and by-products of chlorine which are cancer-causing elements, and thus reducing the chances of contracting rectal, colon and bladder cancers.
By filtering the water supply, the elements giardia and cryptosporidium are removed from drinking water and this actually reduces the chances of contracting gastrointestinal disease by up to 33%.
Clean and properly filtered drinking water used for cooking purposes will give us better tasting as well as much healthier food.
There are over 2,100 known toxins in the water supply and thus a proper filtration system has the potential of eliminating the many sources of potential ill health in human beings.
Mineral and PH
Another feature of a good water filtration system is the ability to retain the healthy mineral deposits and even establishing the right pH balance for the water as well.
…and for future generations!
Safe-guarding Children’s health is of paramount importance and since children are particularly susceptible to water-borne diseases and illnesses, filtration will produce safe drinking water. Having access to purified drinking water is vital to the proper development of children.
A good water filtration system is less costly than buying bottled water because the filtration system has little need of expensive maintenance. There is only the need to clean and replace the filters on a regular basis.
Types of water filtration
Water treatment plant filters
The types of water filters include screen filters, slow sand filter beds, rapid sand filters, media filters, cloth filters, disk filters and algae scrubbers.
Portable Water Filters
These water filters are small, lightweight and portable, suitable for use by hikers, the military and aid organisations during humanitarian missions. Here dirty water is entered via a screen-filtered flexible silicon tube through a special filter which is able to remove disease-causing bacteria and water is caught into a container, safe for drinking.
These are filters for domestic use and they include metallic alloy filters, granular-activated carbon filters (GAC), microporous ceramic filters, microfiltration & ultrafiltration membranes, carbon block resin. These are devices which can be directly installed at the water outlets (showers and faucets) and they are capable of screening against potentially harmful water-borne organisms.
How it works
Physical filtration involves the straining of water to remove larger impurities. Chemical filtration involves passing the water through an active material that removes impurities chemically. There are several methods of filtration.
Activated carbon granules (or active carbon or AC) comes from charcoal which is a very porous form of carbon, commonly used in household water filters. The charcoal’s internal surface area is covered with nooks and crannies that attract and trap chemical impurities through a process called adsorption.
Charcoal is able to remove many common impurities (including chlorine-based chemicals, pesticides and industrial solvents), but charcoal is not able to remove heavy metals, limescale, sodium, nitrates, fluorine, or microbes. The main drawback of activated carbon is that the filters eventually get clogged up with impurities and will need to be replaced adding to the costs of maintenance.
Reverse osmosis is a process where contaminated water is forcibly passed through a very fine membrane, which acts as a filter, so the water passes through but the contaminants remain behind.
Boiling water is one of the ways to purify water. Heat will kill off many different types of bacteria but it doesn’t remove chemicals and other contaminants. Distillation is a process whereby water is boiled to generate steam and the steam is captured and allowed to condense back into water in a different container. Since the boiling temperature of water is lower than that of its toxic heavy metal contaminants, the contaminants will remain behind as the steam separates away from the contaminants.
Ion-exchange filters are very good at removing limescale and these filters make use of a process which splits the atoms of a contaminating substance into ions. Then they trap those ions and release, instead, some different but less troublesome ions of their own, thus exchanging “bad” ions for “good” ones.
Water filtration using Nanotechnology
Researchers at the Indian Institute of Technology has developed an extremely cost effective nanoparticle water filtration system with the capability of removing chemical particulates like lead and arsenic from the water. Ions are released that trap the contaminants chemically. On the other hand, the purifier is made up of several layers of membranes which act as a strainer to block the contaminants.
