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 present times, all sources need verification through chemical assessment so as to be considered safe. Even what may appear clean might not be necessarily safe for consumption or food preparation. Indeed, minimal standards require that all sources be approved before any harvesting and use is initiated. Potentially harmful components as chemicals, heavy metals, fungi, bacteria and viruses need to be taken care of if present. Their effect could have a far reaching effect and should not be ignored.
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.
Filtering process can further be carried out at finer levels intended to eliminate as many pollutants as may be possible. Membrane filters are suitable for this purpose. Despite their effectiveness in isolating many undesired components, they are still unable to control or remove dissolved ions. This implies that undesired heavy metal ions are left in place even when these filers are used.
One main way of controlling dissolved ions is through chemical ion exchange processes. Chemicals like calcium and magnesium ions are removed through an ion exchange process. In this process, least troubling ions are instead discharged into water. Better still, ultra filtration membranes may be very useful in complete separation of heavy ions before fluid is ready for use.
Finally, safe water is necessary and required for various operations. It is very wise to use sources that meet the basic thresholds in terms of standards set. Anything outside this bracket is very unsafe and therefore should be avoided.
