1. Intake with screen removes floating, large solid impurities. The removed solids are called screenings, and they are treated and disposed as solid wastes. Mixing tank is where coagulants such as alum, aluminium sulfate, ferric chloride, ferrous sulfate or lime are mixed with raw water (Al-Najar), there is no waste stream generated from mixing tank since the process is quick and there is no time to settle. In, the flocculator slow mixing occurs to allows for floc formation, the chemicals added in mixing tank promote this process. Flocculated suspended impurities settle sooner due to their large size and mass. ...

I agree with the statement. Some key advantages of zero waste management necessitate adoption of stringent approaches to waste management. These advantages can be categorized into environmental, social, and/or economic benefits.
