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.
Filtration process intended to achieve purification may take many approaches. Intended use of resultant fluid dictates the approach or approaches suitable for achieving desired end result. When filtering fluids, the intention is to separate large sized materials. All the same, different filtering units remove different sizes of impurities. For this reason, various items may be very necessary to filter out different items. Gravel and sand of different diameters may therefore be employed.
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.
Slow sand filters are therefore a second sand filtering process intended to improve quality and value. It is composed of more fine materials than rapid filtration option. It is relatively slow and a large surface area is required for efficiency. In this process, even very fine pollutants are eliminated and resultant product is considered safe for use even without additional treatment options. All the same, additional care may be necessary to maximize safety.
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.
