28家反渗透（RO）水处理厂对一项调查做出了回应，以获取有关此类处理装置问题类型和原因的信息。此外，还要求运营商提出建议，以改善其特定系统的性能和运行效率。调查涉及以下方面:工厂关闭和不运行的原因；治疗目标；水资源和需求；储存设施；电源；操作员和维护人员的培训和经验水平；预处理；泵；给水电导率；膜；盐水处理； 清洁溶液；警报和关闭规定；监测设备；治疗后；以及运营和资本成本。总结了反渗透系统存在的问题和解决方案，并对今后的安装提出了建议。包括4个参考文献、表格和图表。

Twenty eight reverse osmosis (RO) water treatment plants responded to a survey to obtain information on the types and causes of problems with such treatment installations. Operators were also asked for suggestions to improve the performance and operating efficiency of their particular system. The survey covered the following areas: reasons for plant closings and inoperation; treatment objectives; water resources and requirements; storage facilities; power supply; training and experience levels of operators and maintenance personnel; pretreatment; pumps; electroconductivity of feedwater; membranes; brine disposal; cleaning solutions; alarm and shutdown provisions; monitoring equipment; posttreatment; and operating and capital costs. RO system problems and solutions are summarized, and recommendations for future installations are suggested. Includes 4 references, tables, figure.
