Improving the quality of water involves disinfection plus purification of untreated surface and ground water.
Community Level
A public/private water treatment facility aims to make water safe to drink and pleasant to taste, while also making sure that there's enough water to produce the wants of the community.
Raw, untreated water comes from an underground aquifer (via wells) or surface water sources like a river or lake. It flows or is pumped to remedy facility. The minute it's there, the water is treated beforehand to remove debris - like leaves and silt. Then it undergoes some treatment processes, such as disinfection and filtration using chemicals or physical processes, eliminating microorganisms that cause diseases. Once the therapy is completed, water flows out by way of a system of pumps and pipes, which can be often called the distribution system. water purifier price in bd
There is a slight difference of water treatment process at various places, on the basis of the technology of the plant and water would have to be processed, however the fundamental principles are mostly the same.
Coagulation / Flocculation
At the coagulation state, liquid aluminium sulfate or alum, and sometimes polymer, is put in untreated/raw water. This mixture causes tiny dirt particles in water to be fastened together or coagulated. Then, collections of dirt particles join together to make bigger, heavier particles - referred to as flocs - which are typically removed through filtration/settling.
