Drinking Water Filtration Systems Are Simple And Safe

By Jordan Schmidt


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.

Not all sources are safe and good enough for consumption before processing. N the present times, even a spring has to be investigated before it is pronounced safe as used to be before twentieth century. The processing chain may be complex and have varying costs depending on the purification level desired. Some of the constituents that are often eliminated in these processes include algae, fungi, bacteria and solid wastes.

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.

After removing large suspended items, it is necessary to perform a step by step value addition. This is achieved by filtering resultant fluid from which large suspended solids have been removed. Filtration occurs in steps and sequence. The initial phase is rapid sand filtering units designed to eliminate relatively small undesired components. It is quick and large amounts of fluid can be prepared in a short while. Fluid being prepared passes from top vertically down with aid of gravity leaving behind all the undesired components.

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.

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.
