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.
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.
A second filtration options serves to eliminate even smaller entities suspended. In fact, the resultant fluid can directly be consumed as it is free from most impurities as well as pathogens. Disease causing organisms like amoeba are filtered out in this process. However, dissolved chemicals including heavy metals cannot be eliminated this way and therefore require other finer options.
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.
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.
