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 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.
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.
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.
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.
