How is water cleaned
 | Clean drinking water is a basic necessity among human beings and all other living things. We have seen and experienced how empires were created and destroyed because of water resources thus we can conclude that clean drinking water is really important and can be considered one of the building blocks of a community and country as a whole. In most countries, the government teams up with a private company to supply drinking water to the residents. The cleanliness of the water will usually depend on how they manage the filtration process of the water to be delivered to households. There are instances of water contamination that are reported from time to time due to the mixing of chemicals that should not be included during filtration. Other factors like old, rusted water pipeline or poor water treatment can cause water contamination. How is water cleaned It is important for us to be know the water filtration process in order for us to understand well how our drinking water is cleaned before distributed to our homes. Well, here are the basic steps of water filtration: 1.) The first step is coagulation. This process is used to clump all together particulates by adding coagulants like alum and lime to the water for easier filtration. 2.) The next step is when water enters a much larger clump process which is called flocs. 3.) The third step is sedimentation. This is the process where water is allowed for 24 hours to stand down to let the large clumps settle to the bottom. 4.) The fourth step is the process where the water is filtered and disinfected using chlorine. 5.) The final stage is the aeration. This is the stage where contaminants like radon were removed. As you can observe now portable water purifiers that are introduced in the market uses gravity-based water filters because it follows the basic steps of filtration. A water purifier is separate by two levels wherein the upper level is where the water is placed for filtration and as gravity pulls down the water through a special mix filter, it automatically goes down to the second level. On the second level, the water is now ready for drinking. Although the technique is effective, it usually takes time especially when the filter has been used for days and it is already clogged by contaminants. A more effective way of water filtration is the one being used by some small bottled company wherein they use different machines for liquid purification. This is a much efficient way of filtering the H20 we drink. how is water cleaned |
