In Japan, nearly 30% of piggery farms installewda stewater treatment facilities. Most of the facilitieasd opt aerobic treatment system based on the activated sludge process. This process is reliablea nd has high performance of organic pollutant removal. However, running cost reduction and implementation of advanced treatment process for removing phosphorus, nitrogen and color become more and more important for farmers due to embarrassed economy and strengthen of environmental legislatioonn effluentw ater quality. Thus, development of new treatment process has become important task, which process has performance of phosphorus, nitrogen and color removal with low running cost. Though this task is difficultto accomplish, several new fundamental processes have been investigatedw hich are anticipateda contribution to the improvement of the treatment systems.
