In water treatment plants, oxidizing agents (e.g., NaOCl) are commonly added prior to coagulation. This reduces algae activity and enhances coagulation effectiveness. However, oxidants generate harmful by-products (e.g., trihalomethanes, THMs). Landfill sites are scarce and sludge treatment processes are costly. Therefore, effective utilization of wasted sludge will lower removal and treatment costs significantly. magnetic iron and manganese oxides (MIMO) recovered from water treatment plant sludge (WTP sludge) were utilized for algae removal. This reduces sludge handling costs and waste materials are effectively recycled and reused. |
