Treatment of paper mill wash water using combined ozonation and upflow anaerobic sludge blanket (UASB) process at different system configurations and hydraulic retention times

The efficiency of a treatment process for paper mill wastewater (PMW) using and upflow anaerobic sludge blanket (UASB) reactor at various hydraulic retention time (HRT) values integrated with ozonation as pre- or post-treatment was investigated. In each process sequence, the UASB reactor was continu...
