Which is the best treatment process for removal heavy metal (As, 10-30Microgram /lit concentration) and Fe (20-80 Microgram /lit )? The effluent flow rate is about 5 m3/s.
Given the high flow rate of 5 m3/s, a coagulation/flocculation followed by sedimentation/filtration process may be the most cost-effective option for removing both As and Fe from the effluent. However, the specific treatment process selected will depend on a variety of factors such as the concentration of other contaminants in the effluent, the required effluent quality, and the available budget for treatment. It is recommended that a water treatment specialist be consulted to determine the most appropriate treatment process for your specific needs.
