对于使用“permasep”中空纤维芳香聚酰胺膜的大型反渗透脱盐厂来说,膜的更换率是予算运转成本所必需。本文概述了膜的长周期平均更换率,最初安装的那些渗透器的实际应用,以及膜更换到工厂设计性能的标准,膜寿命,备用生产能力和备用架空间等 For large reverse osmosis desalination plants using “permasep” hollow fiber aromatic polyamide membranes, membrane replacement rates are necessary to anticipate running costs. This article provides an overview of the long-term average replacement rates for membranes, the practical applications of those permeators that were initially installed, and the criteria for membrane replacement to plant design performance, membrane life, spare production capacity, and spare rack space, among others.
