Improve the domestic wastewater quality by using natural materials by coagulant method

Abstract

One of the main industries that produces waste water is domestic waste water. When untreated wastewater is dumped into open spaces or bodies of water, the ecosystem is permanently harmed. Thus, wastewater treatment is required. The following processes are used in wastewater treatment: biological processes, chemical reactions, sedimentation, filtration, coagulation/flotation, and precipitation. Due to their expense, each approach offers advantages of its own as well as application-specific constraints. The need of the investigation was to optimise the coagulation technique and determine if natural coagulants could replace the commercial synthetic coagulants now in use, such as aluminium sulphate.
