采用微滤（MF）和粉末活性炭（PAC）相结合的方法处理含有机物污染的水体。PAC通过去除腐殖质等溶解有机物，减轻了膜污染和浓度极化的影响。本研究以三氯乙烯（TCE）为模型污染物，以去离子蒸馏水和加州渡槽水为背景溶液。TCE去除率达99.8%，溶解有机物去除率达60%。很容易维持10-20 m3/m2/d （250-500 gpd/sq ft）的稳态渗透通量。据估计，每1 000加仑处理过的水，用氟化氢聚磷酸钠处理的总费用为1.27美元。近年来，开发和应用高效、经济的技术来处理被合成有机化学品（soc）污染的水已成为一个重要的问题。一些地下水调查已经证明了这一点
Microfiltration (MF) and powdered activated carbon (PAC) adsorption were combined to treat waters contaminated with organic compounds. The PAC mitigates the effects of membrane fouling and concentration polarization by removing dissolved organic matter such as humic substances. The investigation used trichloroethylene (TCE) as a model contaminant and deionized distilled water and California Aqueduct water as background solutions. Removals of >99.8 percent of TCE and >60 percent of dissolved organic matter were achieved. Steady-state permeate fluxes of 10-20 m3/m2/d (250-500 gpd/sq ft) were easily maintained. The total cost of treatment with MF-PAC was estimated to be $1.27 per 1,000 gal of treated water. A three-layer membrane transport model provided a qualitative appreciation of the MF-PAC In recent years, developing and applying efficient and cost-effective technologies for treatment of waters contaminated with synthetic organic chemicals (SOCs) have become important. Several groundwater surveys have shown that
