The diagram represents sea water treatment plant that undergo various process starting from screening the water at an early point and on other hand transporting the treated water to different users.
To begin with, sea water first undergo the process of intake screen, while this process helps to avoid damage to aquatic life. Moving further, the same water is passed through big pump and reached flash mix for further mixing with other elements like polyluminum chloride oxidants. After this process, water passed through flocculation chamber and simultaneously, passed to settling Basin. According to the diagram, water stopped for some time in the settled tank so that water and other particles get separated, thus this process is a time consuming process in the whole plant. Eventually, the filtered water pass through the pump for further mixing with chlorine and through long pipe it reached filter membrance where water collected and passed through disinfection process which is the final stage for water treatment, while in the disinfection box, chlorine, lime or ( sodium hydroxide)and fluoride are mixed together to protect the water from unseen infections. At the end, the purified water supplied to faucet in various households.
Overall, the diagram depicts the stages of water treatment from intake screening in the beginning and purifying water in the end.
