Water treatment is a procedure that involves many operations (physical, chemical, physicochemical, and biological), with the aim of removing or reducing pollution or undesirable properties of water to produce water that is suitable for the intended usage. Unfortunately, only 2.5% of the water in the world is freshwater, and only 0.4% of this is suitable for human use. Therefore, to fulfill the expanding requirement of the world population, water treatment is becoming more and more important.
To understand more about the water treatment process, interns from Water Watch Penang carried out a few water treatments by using a water treatment education kit. There are 4 sets of experiments carried out, which includes adsorption, filtration, membrane process, and coagulation.
