在膜法深度净水系统中,膜单元的电耗是主要的运行费用。以活性炭、反渗透膜深度净水系统为研究对象,通过理论及实验分析,得出了反渗透膜实时运行电费模型。通过该模型,可以通过在线监测膜分离单元膜通量Jw、回收率m运行参数,以实时计算膜分离单元的电耗,对于工程的最优化经济运行有一定的指导作用。

Energy charge of membrane unit is the most important operating cost in advanced membrane water treatment system. Based on the experiment and theory study of activated carbon and advanced water treatment system of reverse osmosis, reverse osmosis real-time run energy charge model was developed for real-time power estimation of membrane through real-time measurements of membrane run parameters such as membrane flux and coefficient of recovery in the membrane separation unit. The model can be used in the optimization of economical operation of full scale membrane water treatment system.
