Inadequate and unsafe water use is one main cause of morbidity and or mortality in the society. Healthy sources of this commodity are therefore required for a successful growth in both social and economic activities. The beauty of clean and safe sources cannot therefore be over emphasized. No single individual would wish to consume contaminated fluids. Concerned authorities have equally employed varying measures intended to attain this goal. One such measure is installation of drinking water filtration systems.
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.
A second filtration options serves to eliminate even smaller entities suspended. In fact, the resultant fluid can directly be consumed as it is free from most impurities as well as pathogens. Disease causing organisms like amoeba are filtered out in this process. However, dissolved chemicals including heavy metals cannot be eliminated this way and therefore require other finer options.
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.
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.
