With so much water pollution in place, treating water becomes one of the most prime factors in saving the planet and surviving in a healthy and clean surrounding. Water treatment is cleaning the water of contamination and impurities to keep it as pure as possible to be used for various purposes after doing so. This purity is usually impossible if the water is untreated and contains too many impurities to adapt as a raw material for any other use.
How is water treated?
Before all the primary processes, water is filtered and masses of untreatable solids or semi-solids are separated to make it easier. This process is carried out by sedimentation, sieving, etc. that removes dense and floating particles respectively. After this, the water is treated for purity through procedures like:
Coagulation: During this process, few chemicals are included along with a primary coagulating chemical. This chemical agent helps in breaking down the organic matter in the water that requires treatment. The coagulant is vigorously shaken to disperse into every part of the water properly so there is no spot left. After it has set in for a while, it joins together fine particles to cluster them together so they can be removed through filtering processes like settling, skimming, etc.
Flocculation: In this task, large pedals or mixers are used to stir the coagulated water. This stirring allows the bundles of impurities to come to the surface and join together with other bundles. This activity makes it easier to remove the impurities easily since they are all collected together and do not need to be individually searched for and filtered.
Sedimentation: After constant mixing, the water is left undisturbed to settle where the heavier particles are collected down due to gravity. This process helps in removing the particles that are unnecessary through openings. The clean water from the top is collected through pipes and ducts while also going through a filter to remove huge items still present in the cleared water.
Disinfection: Various chemicals are dispersed into the water with disinfectants that clear the water of toxic elements that make it unusable for later processes. Chlorine is one of the highly used disinfectants that kill most bacteria from the water. Microscopic organisms are also affected by these disinfectants so it provides thorough cleansing that is impossible to spot with the naked eye.
Filtration: During this process, the water is run through coarse elements that can strain elements still present in the water after disinfection. These might be elements like sand or coal that trap impurities from further proceeding. There is also a backwash where the water is manually and vigorously shaken the other way to make sure every possible unwanted element.
These five processes are key during every kind of water treatment while the treated water is used for various purposes like drinking, desalination, and more. Wastewater treatment is one of the most common types of treatment in all areas of society since it is followed through in a mass. Water cleanliness can go from dark coloured unclean water to clear reusable water.
This way, water can be made useful for not just purity purposes, but also to improve the taste and smell, also making it potable. It is the most secure process that reduces diseases and health risks that one might face if the water is contaminated whether it is directly consumed or is around someone. Untreated water can always attract flies, bacteria, and diseases that can spread through air or soil contamination on which crops are grown, thereby affecting every individual. It is crucial to stay safe and steer clear of contaminated water. Read more articles at europeanmagazine.
