A Close Examination of the Detergent Destruction Method for Aerobic Treatment of Wastewater High in Detergent (WHD) Content
Detergent wastewater has to be treated to prevent water pollution, especially for the reclamation of large quantity of laundry wastewater for reuse. A detergent destruction method removes detergent by using it to breakdown the activated sludge so as to prevent foaming when aerated in an SBR. Many research studies had reported methods and effects of increasing sludge reduction. A close examination of detergent destruction method to treat WHD has agreed well with the literature that activated sludge disintegration by consuming the detergent in wastewater has significantly reduced the activated sludge amount by mixing with and without aeration. The high rate of sludge reduction with detergent destruction is comparable to sludge reduction with ultrasonic and other methods. This provides an economical and efficient way to breakdown sludge in improving the wastewater treatment process.
