Sedimentation and filtration have been widely employed for drinking water treatment to separate dissolved and particulate fractions from solution, which are the simple, effective, and low-cost approaches to improve overall water quality [46, 47].Sedimentation is a pretreatment technology in water treatment, which can remove one or more substances from a solution ...
Water Treatment: Importance & Process
The first step of getting water treated is through coagulation. This involves adding chemicals with a positive charge to the water which should neutralize the negative charge of dirt and other dissolved substances. Such chemicals include iron and specific types of salt. 2. Flocculation.
The Importance Of Water Treatment
The Importance Of Water Treatment. Water is very important for human being and other living things. In human body, more than 70% are fluid such as blood and all these fluid are basically formed by water. Bone marrow needs water to generate blood then blood carries the oxygen from lung to whole body.
