Abstract

The normal activated sludge method is widely used a wastewater treatment technology capable of advanced treatment at a low cost. However, the activated sludge method, by influent overload, water temperature fluctuations, and an insufficient air supply, would be lead to such problems as a sludge bulking and the water quality deteriorations. The amount of wastewater of the paper mills is quite large and the content of SS is also high. The“Bio-attack”system will solve problems mentioned above, because this system is a compact and a high-efficiency BOD processing system.<br>The“COD Cutter”is a bioactivating substance that was developed in order to improve the balance of microorganism groups in the aeration tank and prepare a proper environment for the mutual symbiosis of the complex microbial communities. Its effect is enhanced by maintaining the diversity of complex microbial communities by supplying microorganisum-activating substances.<br>This paper introduces a brief the“Bio-Attach”/“COD Cutter”, its usage, and usage examples.
