Water is not a fixed element in our body, it needs to be replaced in relatively short periods of time. Our body does not have reservoir water resources, it is a variable distribution depending on the actual amount of water. In a period of approximately 20 days a complete exchange cycle is completed in the human body. Despite the enormous importance of water for all biological processes and our general well-being, we lack appropriate criteria for the correct classification of conventional methods for treating water. Who cares about the issue of healthy drinking water, must take this issue into their own hands.
By what filtering methods and other techniques can we improve the water quality of our pipes? There are many technical ways with which we can change the quality of drinking water. Apart from many companies and their products, there are also many ways to filter water. About this article.
The filtration systems treat water by passing it through beds of granular material that remove and retain contaminants. Conventional, slow, sand and diatomaceous earth filtration systems all do a good job of removing most protozoa, bacteria and viruses (if coagulation is used).
Conventional filtration is a multi-stage operation. First, a chemical coagulant such as iron or aluminum salts is added to the source water. Then, the mixture is stirred to induce the binding of the small particles in suspension to form larger lumps or "flocs" easier to remove. These coagulated masses, or "flocs," are allowed to settle out of the water, so that they carry away many contaminants. Upon completion of these processes, the water is passed through filters so that the remaining particles adhere themselves to the filter material.
Direct filtration is like conventional filtration, except that after adding the coagulant, and after shaking the mixture, there is no separate phase for sedimentation. Instead, the particles in suspension are destabilized by the coagulant and thus adhere more easily to the filter material when the water is subsequently filtered.
Biological sand filtration (Bio-sand) is a filtration system at the point of use analogous to slow sand filtration, but its effectiveness is much less established than the latter.
Filtration with diatomaceous earth uses as filter material the fossilized shells of tiny marine organisms through which the water is passed without treatment. The earth physically filters particulate contaminants from water.
Bag and cartridge filters are simple, easy-to-use systems that use a woven bag or rolled filament cartridge or a shirred filter to physically filter microbes and sediment from the source water.
Ceramic filters are mainly used in point-of-use applications. In developing countries, these are manufactured locally, sometimes in self-financed microenterprises.
Traditional way of filtering water is using portable water bottle with filter, which means a water bottle which is having pre-installed filter in it. This is one of the modern way of filtering water.
Most filtration systems use "backwash" to clean the system. This produces wastewater that must be handled properly.
