Abstract |
Traditionally, biological process efficiency is measured by its BOD removal. However, a period of 5 days is required to determine the BOD in wastewater. In detergent, LAS (Linear Alkylate Sulfonate) is a basic organic element which is readily degraded in municipal biological processes. The fact that LAS can be rapidly determined within 30 minutes makes its use advantageous for process control. The results of the study indicate that BOD removal and LAS removal in both, activated sludge and trickling filter processes are significantly correlated. It is very likely that the % LAS removal of a biological process can be used to predict the % BOD removal of the same process. (Modified author abstract) |
