摘要: A composition for preventing formation of slime which comprises a chlorine-based oxidizing agent, a sulfamic acid compound, one of an anionic polymer or a phosphonic acid compound and a process for preventing formation of slime which comprises adding the composition to a water system are disclosed. Troubles caused by slime in cooling water systems, heat-storage water systems, water systems in manufacturing processes of paper and pulp, water systems for collecting dusts and scrubber water systems can be effectively prevented with the composition in a small amount.
