Treatment of Industrial Wastewater Using a Membrane Bioreactor Pilot Scale: A case Study of Industrial Wastewater From a Disposal Pond in Phanomsarakham District, Chachoengsao, Thailand

Abstract

This research studies the efficiency of industrial wastewater treatment using a membrane bioreactor (MBR). By using wastewater from wastewater disposal pond volumes of 300 liters and leachate volumes of 20 liters, aeration was fed continuously to provide the oxygen at an air flow rate of 150 l/min for 24 hours to activate the group of microorganisms. Then put the combined wastewater into the MBR. and then start the treatment system, collect each sample separately every 1 hour for a total of 12 hours, and sample in the 24th hour of the experiment.

The result found that the amount of BOD, COD, SS, TP, and TOC contamination after MBR treatment has a continuous, statistically significant decrease in each hour of the experiment. The removal efficiencies of BOD were found to be 25%, 75%, and 68% (on 5^th, 11^th, and 12^th hours), COD was found at 50.72% and 71.47% (on 5^th and 12^th hours), SS was found at 92% and 94% (on 6^th and 12^th hours), and TP was found at 84.72% and 73.70% (on 9^th and 12^th hour), respectively. and TOC was found at 47.07% (on 12^th hours). The experimental results show that MBR is an effective treatment. can reduce the amount of contamination of organic and inorganic substances in wastewater to a statistically significant reduction. Can use a membrane biological reactor tank treatment system to apply wastewater treatment in the field. For use with wastewater with high toxic contamination, other elements and specific groups of microorganisms should be studied to be appropriate for the type of wastewater.
