The application of CAF process in the zero discharge of paper mill effluent

Recently, the technology of closed circle and zero discharge has become one of the important research projects on treating technology in paper mill effluent. Many foreign pulp and paper enterprises taken waste paper as raw mate- rial have realized zero discharge. In China, the research and practice of zero discharge technology for enterprises using waste paper as raw meterial also see a rapid development. The process of cavitation flotation process (CAF) is a new flotation process with the advantages of being small in equip- ment volume, low in investment, small in floor space and low in energy consumption and the zero effluent discharge for paper mills can be realized by circulation and reclamation.
