Abstract
As an eco-friendly substitute to commercial coagulants, the Mineralized Coagulant was produced and its algae and nutrient control efficiencies were evaluated. The raw water of a reservoir (chlorophyll-a = 48.0 mg/㎥, total organic carbon = 95.3 mg/L) was treated with the mineralized coagulant and other commercial coagulants. After the coagulation, monthly analyses of chlorophyll-a, organic matters, and nutrient concentrations were performed twice. The mineralized coagulant showed 96% of chlorophyll-a and 94% of total organic matter removal efficiency while the range of all coagulants were 75% to 99% and 50% to 96%, respectively. For the nutrient, the mineralized coagulant showed the higher removal efficiency (83% for total nitrogen and 93% for total phosphorus) and the lower release from the coagulated algae than most of other coagulants.
