COMPOSITION, SYSTEM, AND METHOD FOR TREATING WATER SYSTEMS

A composition for treating a water system or membrane fluid system, such as a reverse osmosis system, to remove scale, microorganisms and biofilm, and corrosion by-products. The composition compriseschelating agents and a surfactant. The composition may be a solid dissolved by water or solvent in the system being treated or may be a pre-mixed foam or aerosol. A method for using such a treatment composition comprises contacting the treatment composition with substantially all parts of the water system and draining the treatment composition from the system before resuming normal operations. Forcertain systems, the method also comprises draining some existing water in the water system to remove prior treatment compositions and filling or rinsing the system with fresh water prior to adding the treatment composition. 用于处理水系统或膜流体系统，如反渗透系统以除去污垢、微生物和生物膜以及腐蚀副产物的组合物。组合物包含螯合剂和表面活性剂。组合物可以是通过被处理的系统中的水或溶剂溶解的固体或者可以是预混合的泡沫或气溶胶。使用这种处理组合物的方法包括将处理组合物与水系统的基本上全部的部分接触并在恢复正常操作之前从系统中排出处理组合物。对于特定系统，该方法还包括排出水系统中些存在的水以除去先前的处理组合物并在添加处理组
