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.
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.
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.
Filtering process can further be carried out at finer levels intended to eliminate as many pollutants as may be possible. Membrane filters are suitable for this purpose. Despite their effectiveness in isolating many undesired components, they are still unable to control or remove dissolved ions. This implies that undesired heavy metal ions are left in place even when these filers are used.
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.
Let all persons be safe. Safety is necessary for disease prevention. It is one way of reducing disease burden on a population.
