Reduction in effluent load by proper wet-end chemistry

Abstract

In recent paper industry, global environmental protection is a big concern beside productivity, run ability and quality improvement, Increased recycled fiber usage promoted by global resource protection and environmental concern brings more foreign materials such as pitch and anionic trash in paper-making system. At Somar we have been working on wet-end improvement agent "REALIZER A Series" as functional coagulant which maximizes the effect of variety of wet-end chemicals. Latest polymer technology help us to develop another functional retention aids as "REALIZER R Series" and "REXER FX Series" which are effective in fine and ash retention. Synergistic effect of the combination of these chemicals to improve wet-end performance is referred as "AXISZ SYSTEM". In addition to these chemical developments, long experience in slime control technology in papermaking process at Somar helps us to develop most effective biocide system "CURECIDE SYSTEM". The optimum wet-end control system could be built though the use of our chemical system which gives maximum effect with minimum chemical dosage. Possible reduction in many wet-end chemicals contributes lowering effluent load as well. This paper describes the effect of reduction in effluent load by optimizing wet-end operation using "AXISZ SYSTEM" and "CURECIDE SYSTEM".
