Simultaneous sludge minimization, pollutant and nitrogen removal using integrated MBBR configuration for tannery wastewater treatment.

An advanced operational configuration of anoxic-aerobic moving bed biofilm reactors (AMOMOX process) was experimentally demonstrated to achieve simultaneous sludge yield minimization, pollution and nitrogen removal. The AMOMOX experimentation witnessed considerable variation in process parameters while feed operation changed from synthetic wastewater to real tannery influent. The strict maintenance of operational strategies resulted prominent removal of TCOD, SCOD, ammonia nitrogen and total nitrogen higher upto 93.
