Water and water sources must be kept safe. Safety is necessary and must be guaranteed before any source is used for drinking or in meal preparation. Unsafe sources are associated with morbidity and mortality. This is a commodity that is used by all persons all over the world and there is no life without it. Drinking water filtration systems must therefore be effective and efficient.
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.
When all large solids have been eliminated from targeted sources then minor pollutants must equally be dealt with to improve its safety level. The very first form of filtering mechanism involves use of rapid sand filtration system. The sand used in this case must allow quick drain through sand layer and is intended to trap only large sized items. Microscopic materials find their way down the filters and therefore call for additional filtration process.
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.
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.
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.
