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 a barrier has been used to get rid of large floating or rather suspended objects, a filter process is initiated. First, large sized sand particles are employed. It is termed as rapid sand filtration. It is rapid because it allows a lot of fluid to sink through it within a short time. Despite the faster rate, it is very effective in trapping unwanted components. For continued effectiveness, it must be freed from trapped components time after time.
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.
Another possible unit suitable for achieving pure fluids is ultra filtration membrane polymers. They are effective and equally efficient. A little pressure is needed to drive component being filtered through the small micro pores. Only desired component is allowed to go through while others are retained. To make the process more effective and complete, ion exchange devices and or system is included.
Let all persons be safe. Safety is necessary for disease prevention. It is one way of reducing disease burden on a population.
