The Treatment of Synthetic Wastewater Contains Linear Alkyl Benzene Sulphonic Acid (LABSA) in Membrane Bioreactor (MBR) System

One of the most important raw material in the detergent production process is a Linear Alkyl Benzene Sulphonic Acid ( LABSA ). Nowadays, LABSA isused as main surfaces active ingredient in the liquid, gel or powder detergent process. Thus, there is often in the city wastewater. Therefore, there is a need for alternative methods to eliminate surfactant from large volume of wastewater by an effective and economical way. Membrane bioreactors (MBR) systems have significant potential in treatment technologies. This technology is particularly suitable for the treatment of domestic sewage and industrial wastewater as compared to conventional activated sludge process has come to the fore with great advantage. In this study, the treatment studies of synthetic wastewater containing 300 mg /L LABSA concentration was carried out by Aspergillus versicolor and Trametes versicolor mixed culture in the lab/pilot scale membrane bioreactor (MBR) system at non-sterile conditions. For experimental measurements, a sampling performed every 24 hours and the samples were analyzed according to standard methods. The removal efficiency of LABSA reached 58 % within 48 hours.
