Adequate and safe water is necessary for a healthy population. It keeps many diseases at bay and enhances productivity of a community. It can therefore not be overlooked for this shall hamper all social and economic progress of a people. No one desires such a thing and therefore everyone seeks to be on the safer side. At this point in time, it is worth noting that drinking water filtration systems have been erected so as to enhance safety and better health.
In the past centuries, pollution was not a major concern of communities living then. There was no serious pollution causing industries as there are now. Then, some sources could be used without prior check or tests conferring proof of safety. This practice is no more and all water sources including springs require verification before use. Processing chain may be very complex or simple depending on amount of water involved and the purpose for which it is being processed.
Purification chain may take different approaches. This is dictated by various reasons for which quality is being improved. Filtration process is necessary so as to eliminate solid materials that can be filtered off as floating objects. Different sizes of gravel to fine sand are used to attain this goal. Better still, additional chemical use may be very necessary in improving water by eliminating suspended soil and other dirt. Additional mechanisms include boiling, distillation as well as chemical treatment.
When all large solids have been eliminated from targeted sources then minor pollutants must equally be dealt with to improve its safety level. The very first form of filtering mechanism involves use of rapid sand filtration system. The sand used in this case must allow quick drain through sand layer and is intended to trap only large sized items. Microscopic materials find their way down the filters and therefore call for additional filtration process.
Other than rapid filters, slow filters are employed to eliminate even smaller impurities. Just like rapid system, sand is still the primary component in this option. However, small fine sand is used in this case. Unlike rapid system, it is slow and takes a lot of time to prepare adequate supply that can meet the needs of a community. Following this, it is usually situated in places with adequate space to provide large surface area.
Third in this category are the membrane filters. They are fine and very useful in removing additional fine impurities. A positive pressure is needed to drive the fluid through these small pores. Fluid resulting from these processes may not be as pure as those obtained through distillation but contain minimal contamination and are therefore safe for human consumption.
For effective elimination of these undesired dissolved ions, it is necessary that ultra filtration membrane polymers are used. These forms of filters are fine enough and are designed to aid elimination of undesired chemical constituents. In addition, ion exchange strategies allows for efficient elimination of undesired components in exchange for less harmful ions that do not threaten health.
Whatever the case, all persons should always consume safe water. If possible, only trusted sources should be used for drinking. Unapproved sources may be lethal.
