A microfiltration-membrane-coupled bioreactor (MMB) on pilot scale was operated for 135 days to investigate its technical feasibility in urban wastewater reclamation. Different operation parameters such as sludge retention time from 5 to 30 days, hydraulic retention time from 3.75 to 7.5 h, and membrane flux from 50 to 100 L.m -2 .h -1 , were tested. The highest sludge concentration...
A 162-day pilot-scale operation for reclamation of urban wastewater was studied by using an ultrafiltration membrane bioreactor (UMBR). Performance of the UMBR was investigated with a sludge retention time (SRT) of 5, 15, and 30 days, a hydraulic retention time (HRT) of 5h, and membrane flux between 75 and 150lm -2 h -1 , respectively. It was observed that the highest sludge...
