Schematic diagram of water filtration plant, showing all steps, screening, sedimentation through alum and clarifier, then sand filteration and then pumping to over head reservoir.
To design a water treatment plant first and foremost thing is calculation/estimation of plant capacity in which plant has to run up to design period without trouble.

TESTS PERFORMED
Removing Hardness • SOFTENING • The two basic methods of softening public water supplies are – chemical precipitation (Lime and Soda ash) and – ion exchange.
• Other methods can also be used to soften water, such as electrodialysis, distillation, freezing, and reverse osmosis. • These processes are complex and expensive .
Lime and Soda Ash • The chemicals normally used are lime (calcium hydroxide, Ca(OH)2) and soda ash (sodium carbonate, Na2CO3). – Lime is used to remove the chemicals that cause the carbonate hardness. – Soda ash is used to remove the chemicals that cause the noncarbonate hardness. • In this process Calcium and Magnesium ions are precipitated by the addition of lime (Ca(OH)2) and soda ash (Na2CO3).
