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 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.
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.
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.
