APPLYING SUPERWATER TO CONTROL SLIME PULP DURING PAPERMAKING AND OPTIMIZE CLOSE SYSTEM OF WHITEWATER

摘要

Superwater is a new technique for controlling slime pulp and optimizing close system of whitewater. This technique has a special generator. It will produce hypochlorous acid, and the hypochlorous acid has a steady concentration and pH value with this generator. Through this method superwater is provided with better bactericidal ability and high oxidizability. The article introduced the superwater’s action principle for controlling slime pulp and its virtues. And then it studied its bactericidal and ameliorative actions in close system of whitewater. The article also compared superwater with other conventional bactericides. At the use level, concentration, actuation duration and bactericidal ability, superwarter system excelled conventional bactericides. Furthermore the superwater can improve a series of problems in close system of whitewater. At last, a pilot scale test about superwater system has been carried out in Chengdu. The test indicated that the superwater in whitewater can increase yield and save cost.
