Water is a basic necessity but also aids enough grounds for water borne diseases to flourish and transmit at the same time; pure drinking water is an integral. Water can be made fit for drinking with storage, filtration and chlorination.
Storage methods: In the above the water drawn from the natural or artificial source is stored adequately to further ensure any kind of pollution in it. As a result of storage, a major percentage of purification occurs in as the 90 % of the physical particles settle with gravity and the density lower and water seems clear. The method also allows the aerobic bacteria to act and impart dissolved oxygen. Moreover, a considerable reduction of biological process halts in properly stored water.
Filtration: The second stage is adequate to settle over 98 % of bacteria.
Chlorination: The process is a huge advancement killing all pathogenic bacteria though it remains unaffected on spores and viruses.
Though the above given steps are otherwise for large scale purification but the following can be adopted at household to ensure and aid every family member a neat, clean, free from any organisms water supply. It is of utmost importance to understand its true application and adopt it without any flaw. Safe water is what we all desire.
Boiling: From times immemorial it is a satisfactory method to purify water and one that can be easily adopted at home. Here the key lies to adopt it in the most right way. Just bringing the water to a boil may not be enough, to be effective water must be brought to a rolling boil for about 4 to 5 minutes. The thorough boil will kill all bacteria, spores, ova and cysts yielding safe sterilised water. Further, boiling also helps remove temporary hardness too though the taste is a little altered but for sure it is safe. The process is an excellent method but comes with just single flaw i.e. it guarantees no further protection of any subsequent contamination, every time you need water you just can’t rely on a stored version (until done in a safe way) and need to boil again or a fresh supply to satisfy the needful. So it is advisable to boil the water in the same container in which it is to be stored later, the momentary step will curtail or else minimise odds. Further every effort should be made to keep this prepared water from any unwanted exposure.
Use household chlorine
Chlorination at small scale is wise to adopt but should never be used hay ware without any prior knowledge. Add about 8 drops of chlorine bleach in about a gallon of water and let the cloudiness settle. Stir and just let the chlorine work its way.
Add a little potassium permanganate
Potassium permanganate is an effective term related to water purification. Add about 2 to 4 crystals per litre of water, stir thoroughly and then let it settle.
Sunlight as we know is an apt natural disinfectant. Allow water to be consumed to be exposed to sunlight for about 4 to 5 hours. But here make sure it is exposed with all possible measures not like an insect just crawls in and go by.
