Application of submerged membrane bioreactor for converting high strength wastewater into clean water

| Izvleček: | The high biomass submerged membrane bioreactor (MBR) showed exceptionally high
performance in organics and nutrients removal for a high strength industrial wastewater
feed. During the 300 days of continuous operation, chemical oxygen demand (COD)
values of the permeate fell to less than 10 mg-L-1 after just 100 days. This would represent
an excellent organic reduction of 99%. It was found from the study that the biological
process of the MBR was responsible for 90-98% of COD removal while the membrane
separation contributed to further 2-10% of COD removal. Total nitrogen (TN) removal
also showed high reductions. Quality of the permeate were better than local tapwater and
typical clean water microfiltration effluent presented an exciting opportunity for the reuse
or recycle instead of discharge into open waters. |
