Some Options Used In Drinking Water Filtration Systems

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.

Different approaches can be used to make this fluid safe for consumption. Choice of treatment option is dependent upon intended use. Some uses require high degree of purity while others may not call for that kind of purity. Filtration offers a great deal of help eliminating various undesired components that include algae, fungi and bacteria growths. In addition, it eliminates large solids and suspended soil particles.

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.

Other than rapid filters, slow filters are employed to eliminate even smaller impurities. Just like rapid system, sand is still the primary component in this option. However, small fine sand is used in this case. Unlike rapid system, it is slow and takes a lot of time to prepare adequate supply that can meet the needs of a community. Following this, it is usually situated in places with adequate space to provide large surface area.

Membrane filters are equally useful. They could be very useful in preparing water for drinking purpose. Better still, these membranes could also provide fluids needed for running engines and preparing foodstuff. One main challenge with this kind of filter is that it does not eliminate dissolved items including heavy metals like mercury.

For effective elimination of these undesired dissolved ions, it is necessary that ultra filtration membrane polymers are used. These forms of filters are fine enough and are designed to aid elimination of undesired chemical constituents. In addition, ion exchange strategies allows for efficient elimination of undesired components in exchange for less harmful ions that do not threaten health.

Finally, safe water is necessary and required for various operations. It is very wise to use sources that meet the basic thresholds in terms of standards set. Anything outside this bracket is very unsafe and therefore should be avoided.
