| IRON FILTERS (OXIDIZING FILTERS) Iron/oxidizing filters are used for treatment of waters with medium concentrations of iron, manganese, or hydrogen sulfide. Iron appears in water in both a ferric (visible and insoluble) and a ferrous (dissolved) state. While ferric iron can be simply filtered from the water, ferrous iron must be oxidized, converting it to the suspended ferric state, in order to be filtered out. The media used in these iron filters is manganese green sand, which is capable of oxidizing dissolved iron and manganese, allowing them to be filtered out in the same tank. Iron/oxidizing filters must be periodically backwashed, to flush away accumulated deposits, then regenerated. After rinsing, the filter is again ready for operation. When such filters are used, they are, in most cases, placed ahead of a softener. SAND FILTERS The sand filter is used for the simple filtration from water of visible dirt or suspended matter (turbidity) due to silt, sand, organic matter, and rust type particles. These units use sand or gravel as the filter media, and are effective in removing sediment and cloudiness from water, except when such turbidity is due to extremely fine particles. Sand filters must be backwashed periodically to clean the suspended matter from the filter media and flush it down the drain. ACTIVATED CARBON FILTERS Activated carbon filters are primarily used to remove objectionable tastes and odors from water, and are effective in removing chlorine. These filters contain activated carbon, a form of charcoal with high adsorptive qualities. Adsorption is defined as the adhesion of a gas, vapor, or dissolved material on the surface of a solid. As water is brought into contact with these activated carbon particles, the taste and odor constituents are retained in the carbon, resulting in a taste and odor free water. Activated carbon filters have also proven effective in the removal of inorganics such as trihalomethanes. The granulated filters must be periodically backwashed, and the cartridges cleaned or replaced from time to time. NEUTRALIZING FILTERS To increase the pH value of a water, which is to decrease the acidity and thus its corrosive nature, a neutralizing filter is recommended. The presence of large amounts of free carbon dioxide gas in solution (carbonic acid) renders a water acid in character, which can cause corrosion damage to the metal components of a water system, including the water pump, piping (iron, galvanized brass, and even copper), tank, water heater, and fixtures. Neutralizing filters contain a bed of materials such as calcite and magnesia. As water passes through this bed, the carbonic acid is neutralized and a small amount of the bed is dissolved. As a result, the water becomes more alkaline (higher pH value) and thus less corrosive. A neutralizer requires occasional backwashing to loosen the material and clean the bed. From time to time, additional material must be added to the bed to replace that which is dissolved. CHEMICAL FEED PUMPS Chemical feed pumps are used to inject corrective solutions into a water supply. For example, soda ash, a highly alkaline compound, is often added in solution to a water supply as an alternate method for reducing acidity. Chemical feed pumps can be wired to operate in conjunction with an electrically operated well or water pump, and multiple solutions can be fed into a water system with a single pump unit when applicable. Chemical feed storage tanks are occasionally an attractive solution to water treatment problems because several chemicals can be mixed and fed together, thus solving several problems at once (e.g. Chlorine for purification and acid neutralizer for pH control). Chemical feed storage tanks must be refilled with the chemical compound periodically. Advantages :-   »  Better testing, quality, chlorine free water in your entire home   »  Great for drinking, bathing, cooking and all uses   »  Healthier skin, hair and body systems   »  Easier to wipe off & clean up   »  Reduces drying time & heat   »  Environmentally safe, no brine discharge   »  No salt or chemicals added   »  No maintenance costs   »  As they require little or no mechanical power, chemicals or replaceable parts, and they require minimal operator training and only periodic maintenance, they are often an appropriate technology for poor and isolated areas. |
