人类经济活动引起的环境变化导致地表水水质迅速变化。活性炭与微滤/超滤工艺结合使用是一种从消费用水中去除有机化合物的应急技术。该混合工艺（AC-MF/UF）利用活性炭吸附杂质的能力以及膜的微生物和颗粒去除能力。陶瓷膜的应用和颗粒和粉末活性炭的使用。通过对原水和出水理化指标的分析，估算了容积渗透通量随时间的变化，比较了单元工艺和复合工艺的效率。对天然沃茨混合过程的数学描述，提出了两种不同的方法，即描述渗透通量随时间变化的模型、“松弛”模型和过滤阻力模型。
Environmental transformations caused by the economic human activity generate rapid changes in surface water quality. The application of activated carbon in conjunction with microfiltration/ultrafiltration processes is an emergency technology for the removal of organic compounds from water for consumption purposes. This hybrid process (AC-MF/UF) utilizes the capabilities of activated carbon to adsorption of impurities and the microorganisms and particles removal ability of membranes. Ceramic membranes were applied and granulated and powdered activated carbon was used. Changes of volumetric permeate flux in time were estimated and the efficiency of the unit process was compared with the hybrid one, analyzing the physicochemical indexes of raw water and permeate. Two different methods have been proposed for the mathematical description of hybrid process of natural waters, that is: the model describing the changes of permeate flux in time, the "relaxation" model, and the model of filtration resistance.
