Max Aqua Limited, Aurangabad, RO, UV, UF Water Purifiers. Home, Commercial and Industrial Water Purifiers in India.

Impurities found in drinking water can be broadly classified into:
a) Suspended impurities such as mud, dust, sand, bacteria, viruses, cysts, etc
b) Dissolved impurities that become soluble in water such as- Pesticides (commonly found in borewell water)
Arsenic & Fluoride (found in groundwell water)
Heavy Metals salts like mercury, lead, copper, cadmium (from industrial wastes)

Dissolved Impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. are harmful to our health. They may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer. They also spoil the taste of water. When these dissolved impurities are removed, the water becomes healthy as well as tasty.

Boiling kills bacteria and viruses but does not remove harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Just as we cannot remove dissolved salts from water by boiling, similarly we cannot remove dissolved impurities from water by boiling.Presence of such impurities in water may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer.

Keep in mind that there have been very, very few problems with water supplied by local water municipalities. A bigger concern is water that is supplied by private wells or springs. If you are concerned about the quality of your tap water have it checked by a state approved lab. If the lab report indicates that there are no health related contaminants in your tap water there is little reason to worry. If you would like to treat your water due to an undesirable taste or odor there is a variety of good water treatment choices available to you.

Reverse osmosis systems produce pure water by forcing untreated water or tap water through a semi permeable membrane. The membrane lets only water molecules pass through directing it to the units storage tank,, the impurities that are separated from the water molecules are forced down the drain. The system consists of both pre and post filters which add additional contaminant removal.

Carbon used in filtration applications is produced by grinding a carbon source - like bituminous coal, peat or coconut shells and heating the material in the absence of oxygen to 1000 degrees to bake off impurities. The material is then subjected to 1600-degree steam to “activate” the carbon. The steam leaves carbon granules filled with cracks and pores, enabling them to store large amounts of chemicals. One pound of activated carbon (the amount in a standard ten-inch filter cartridge) has the equivalent surface area of a 160 acre farm. Carbon removes contaminants in two ways: through adsorption , contaminants are attracted to the surface of the activated carbon and held to it in much the same way a magnet attracts and holds iron filings; and by acting as a catalyst to change the chemical composition of some contaminants. Activated carbon is ideal for removing chlorine, organic chemicals such as many kinds of pesticides, THMs like chloroform and many VOCs that are components of gasoline, solvents and industrial cleaners.

An ultraviolet (UV) system uses UV to inactivate certain bacteria, viruses and cysts that may be present in the water source that flows through the systems UV chamber. The effectiveness of UV depends upon the dose of disinfectant received by the organism, which is the combination of UV intensity times the contact time involved. It is advisable to always pre-treat the water entering the UV system.

Distilled water is water that has been purified by passing through one or more evaporation –condensation cycles and contains essentially no dissolved solids. Usually contains less than 5.0 ppm of TDS.
