本文讨论了用于地表水消毒的两种有前途的集成膜系统（IMSs）:高级物理/化学处理，包括混凝、沉淀、过滤（CSF）、生物活性炭过滤和慢砂过滤，然后是反渗透；然后是微滤和超滤，然后是超低压反渗透。在第一个系统的慢砂滤液中加入MS-2噬菌体表明，反渗透的去除能力为3.4对数单位。亚硫酸盐还原性梭菌孢子的去除被证明是完全的。 贾第虫和隐孢子虫的去除率应与该去除率相等。直接细胞计数和异养平板计数的效率较低。这可能是由于反渗透装置渗透侧的再生。在第二个系统中，经CSF处理的Yssel湖水中存在的指示生物大肠杆菌和亚硫酸盐还原梭状芽孢杆菌的孢子在超滤后减少到低于检测限的值。通常，超滤显示MS02噬菌体完全去除（>5对数）。在引入0的泄漏之后。 2%的去除率仅为2.7对数单位。超低压反渗透显示出较高的去除率（4.7-4.9-log），尽管没有完全去除。在第二个系统中，通过保压试验测量超滤的完整性，并通过颗粒计数进行监测。超低压反渗透完整性通过真空测试和现场电导率进行测量，并通过颗粒计数和硫酸盐去除进行监测。包括8个参考文献、表格、图表。

This paper discusses two promising integrated membrane systems (IMSs) for disinfection of surface water: advanced physical/chemical treatment including coagulation, sedimentation, filtration (CSF), biological activated carbon filtration and slow sand filtration followed by reverse osmosis; and, microfiltration and ultrafiltration followed by ultralow pressure reverse osmosis. Spiking with MS-2 phages in the slow sand filtrate in the first system showed a removal capacity of 3.4 log units for reverse osmosis. Removal of spores of Sulphite Reducing Clostridia proved to be complete. Giardia and Cryptosporidium removal should be equal to this removal efficiency. For direct cell counts and heterotrophic plate counts a lower efficiency was found. Probably this is due to regrowth on the permeate side of the reverse osmosis installation. In the second system, indicator organisms E-Coli and spores of sulphite Reducing clostridia present in CSF treated Yssel Lake water were reduced after ultrafiltration to values below the detection limit. Generally ultrafiltration showed a complete (>5-log) removal of MS02 phages. After an introduced leakage of 0.2% removal was 2.7-log units only. Ultra low pressure reverse osmosis showed a high (4.7-4.9-log) although no complete removal. In the second system, integrity of the ultrafiltration is measured by a pressure hold test and monitored by particle counting. Ultra low pressure reverse osmosis integrity is measured by vacuum testing and in situ conductivity and monitored by particle counting and sulphate removal. Includes 8 references, tables, figures.
