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.
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.
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.
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.
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.
