Recently the importance of the phosphorus management is being augmented according to the designation (2005.12.30 Ministry of Environment) object material in regulation of total emission from the Ministry of Environment. Generally treatment efficiency of biological process is in the process of using is high and treated water quality is stable. However, the process requires wide site area and has difficulties in the advanced treatment for recycling.
Electrocoagulation (EC) process is the electrochemical production of destabilization agents that bring about charge neutralization for pollutant removal.
EC process is compact, so it needs small scale site area and treatment efficiency is high. Also, this process is characterized by reduced sludge production, uselessness of chemicals, and easy operation.
This research escape optimum plan factor for removal of phosphorus in lake by using hybrid system(Electrocoagulation reactor, Settling tank, Filtration tank). As the result electric current : 3ampere, the pH : Neutrality and filtration tank existing the condition was shown the highest removal efficiency. Concentration of PO4-P, T-P and CODcr was measured 0.016 mg/L, 0.022 mg/L and 1.5 mg/L from under condition of optimum, the removal ratio was shown 94.1%, 95.3% and 77.5%. Also expense of the electric coagulation is reduced than expense of chemical coagulation about 0.56 time. so it will be able to forecast the application possibility of electric coagulation.
