PURPOSE: A method for managing waste water using continuous filtration process can remove organic material, suspended solids, and nitrogen. CONSTITUTION: The method is composed of removal process for organic material, nitrification process, absorption process for suspended solids, and effluent process. Wastewater flows into reactor(A) where biological membrane is fixed. Organic materials which are remained after nitrification process are removed by aeration tank, and ammonium nitrate is changed to nitrate. Suspended solids which are remained after fixed biological reactor and solids which are remained after filtration tank flow out through solid effluent pipe. Some of the outflow is returned for removing of nitrate. The compact tertiary treatment process can save ground and money because the process does not need secondary settling tank and extra filtration tank.
