Water Filtering-needless Nuisance Or A Necessity?When we speak of water filtering, we do not usually realize on what a large scale it exists. Beginning with the community level, the municipality waterworks does its bit by keeping the water in holding tanks to induce sedimentation and adding chlorine to kill germs and bacteria.Unfortunately,beyond this there is no further state intervention for the dispersal of clean water. It is unto each institution or household to select good means of water filtering in the interests of hygiene and preserving good health. The U.S. Congress has passed the Safe drinking Water Act in 1974, so that there are certain standards observed as regards the safe permissible levels of dissolved contaminants, bad odors and tastes. There are inorganic chemicals such as arsenic, barium, chromium, coli form bacteria, nitrates and twelve secondary contaminants.Sometimes, depending on the area, or the source of the water; the water is classified as hard and has foaming agents, chlorine, iron, manganese, odors and other total dissolved solids. Bad odors and foul taste are also monitored. Although safety checks are in place, sometimes there could be a higher than permissible level which the average consumer is not aware of. Hence, the necessity of opting for water filtering especially for drinking water. Today, the kind of filters available are so vast and in so many versions that one is spoilt for choice. Water filtering is a technique, which has been refined and re-refined until one can safely say that the filters in the market meet the highest standards of safety. Water filtering removes both dissolved and undissolved matter from the water that we ingest. Since the micron level of the filters is low, even cysts of giardia and cryptosporidium cannot pass through, as they are significantly larger. This ensures that no disease can be passed on through the water supply. Even chloroform fumes, rust, lead particles and odors are trapped by the water filtering system thereby making it safe to drink water straight from the tap without fear of health hazards. In the market for filters.They are broadly classified as filters, distillers and softeners. In water filtering the most commonly used ones are carbon filters, fiber filters and reverse osmosis units. These filters can be fitted onto faucets, pitchers, water inlets etc thereby making sure that every water source is covered as far as filtering is concerned. There are even cartridges for water filtering in refrigerators and coffee units. To sum it up ,we can say that water filtering is a necessary factor to ensure that waterborne diseases are kept at bay and the quality of water is pure and with improved flavor. Bad odors are wiped out and chlorine fumes are erased totally. Water filters are relatively economical and after all a small price to pay for the health of your loved ones. Safe drinking water is and should be the foundation of a healthier life style and water filtering is the key to it. |
