Abstract

Aeration is a major part of the operation cost in biological aerated filtration (BAF) systems for wastewater treatment. This thesis investigated the effect of reducing aeration at the City of Windsor's Lou Romano Water Reclamation Plant to find the lowest possible airflow while maintaining a satisfactory ammonia and biological oxygen demand (BOD) in the BAF effluent. A series of tests were conducted at different airflows in cell #7 at the plant to find the lowest possible airflow while maintaining a satisfactory ammonia and biological oxygen demand (BOD) in the BAF effluent. Profiles of temperature, dissolved oxygen, pH, BOD, ammonia and nitrate concentration were measured along the height of the cell and at different time intervals during filtration, at air flow rates varying from 1300 to 1700 m3/h per cell. This study found that the BOD and ammonium removal were satisfactory at 1300 m3/h airflow rate.
