A method of processing waste water to produce a filtrate is provided. The method includes the steps of: introducing untreated wastewater to an inlet zone of a bioreactor; introducing a concentrate of treated waste water with at least 10,000 mg/L of total suspended solids into the inlet zone of the bioreactor to form a biological active mixture; aerating the biological active mixture in an aeration zone of the bioreactor to produce treated waste water; filtering the treated waste water to produce a filtrate and the concentrate, wherein the filtrate created by the filtering has total suspended solids of less than 10 mg/L; transferring at least a portion of the concentrate to the inlet zone of the bioreactor; and transferring the filtrate external to the bioreactor as clean water.
