The diagram below illustrates the process how water is treated. A quick glance at picture is quite enough to make it clear that the water treatment concludes 10 main stages, beginning with intake screens and ending with taking the water through faucet. First of all, in the water filteration process, after passing through screens and pumos, it enters in to a flash mix which is made from polyaluminium chloride and exidants. The whole work comes under first three stages. In the fourth step, water has to pass through flocculation and settling basin, until it faces to chloride. In the next stage of water treatment, water reaches to the filter membrane. Following this, it comes to disin fection, where the main factors are chlorine, lime or ( sedium hydroxide) fluoride. After that it passes plumps. The final stage of this process consists of going of water through the faucet.
