本文考虑了两种膜残余物管理方案；其中包括使用第二阶段MF工艺或常规沉淀来减少反洗量，以及使用生物硝化/反硝化工艺来去除反渗透浓缩液中的含氮化合物。减少MF反洗量将显著降低下水道处理费用，而去除含氮化合物（尤其是氨）将避免与盐水排放到地表接收水中相关的一些毒性问题。管理MF/UF工艺产生的残余物的选项是通过两级微滤工艺或常规沉淀来减少反冲洗水量。MF反冲洗研究中提出的问题是确定第二级膜表面上较高的固体负载是否会增加膜污染的速率。 沉降研究提出的问题是，是否可以通过常规沉降技术大大降低反冲洗水的高固体含量。管理膜工艺产生的残余物的第二种选择是降低反渗透浓缩物的毒性。通过生物硝化/反硝化可以降低氨氮形式的毒性。包括6个参考文献、表格、图表。

This paper considers two options for the management of membrane residuals; these include the use of a second stage MF process or conventional settling to reduce the volume of backwash and the use of a biological nitrification/denitrification process to remove nitrogenous compounds from the reverse osmosis concentrate. Reducing the volume of MF backwash will significantly decrease sewer handling fees while the removal of nitrogenous compounds (particularly ammonia) will obviate some of the toxicity issues associated with the discharge of the brine into surface receiving waters. Options to manage the residuals produced by the MF/UF process are to reduce the volume of backwash water either by two-stage microfiltration process or by conventional settling. The question posed in the MF backwash study was to determine if the higher solids loading on the second stage membrane surface increased the rate of membrane fouling. The question posed by settling studies was if the high solids content of the backwash water could be greatly reduced by conventional settling techniques. The second option to manage the residuals produced by membrane processes is to reduce the toxicity of RO concentrate. The reduction of toxicity in the form of ammonia nitrogen can be achieved through biological nitrification/denitrification. Includes 6 references, tables, figures.
