Water Purification
Drinking unsafe water may cause a person to fall ill. One can avoid this by using various water purification techniques to ensure intake of clean water. Contaminated water contains bacteria that can inhabit a person?s major organs or even the brain and cause diseases such as cholera. It is very important for a person to take purified water because the body cannot shield itself against all disease-causing bacteria. Home water filters work by eliminating the bacteria in phases and then releasing the purified water to a storage chamber. There are different sources of water, which require different purification methods. Sources of water include the ground, reservoirs and lakes, canals and rivers. Ground water, which probably poured years ago in form of rain, is the purest of all sources because the rock layers naturally filter the water and then pump it into a treatment plant.
Home water filters operate in a similar way though the process is not natural but artificial. Home water purifiers make use of various media when purifying the water. The main component of most water purifiers is charcoal, which is granulated or solidified to avoid making the water dirtier. The charcoal granules prevent big water contaminants from flowing into the next chamber where the termination of small contaminants takes place. Screening of the remaining water occurs in the final chamber, where the final elimination of small contaminants takes place. The home water purifiers may also chemically attract the contaminants into the filter and then treat the water before discharging it into the final chamber.
Besides screening, water filtration may include treatments such as containment and pumping where one can pump the water into a tank that is fitted with filter materials. A person should avoid purchasing home water purifiers that only concentrate on specific contaminants because the contaminants it ignores may cause one to fall ill. One should purchase a water purifier that is about ninety percent effective to reduce the chances of their falling ill. The only way a person can be sure that the drinking water is safe, is by boiling it up to boiling point and then cooling it in a refrigerator. No bacteria can survive extreme heat or extremely cold temperatures. This method is mainly used when purifying water for babies and toddlers. Home water filters are available for purchase in most shops that trade in electrical appliances.
Home water filters make use of the flocculation process, which assists in the purification of water. It clarifies the water by removing turbidity or any pigments in the water and then depositing it into another chamber, where the water undergoes screening. The home water filters clarify the water by forming a precipitate that remains in the water until it is removed in the next chamber where screening takes place. Where necessary, a person may use coagulant agents such as Iron Hydroxide or Aluminium Hydroxide. Sedimentation is the next process after flocculation, where the separation of water from the sediments takes place. The next and final phase is the filtration stage where the separation of the remaining sediments occurs. Most home water purifiers have such systems that make drinking water safe.
