2002年，莫德斯托灌溉区开始实施一项计划，扩大现有的灌溉面积 治疗有效。本文讨论了用于评估和选择低压膜的标准 扩建莫德斯托地区水处理厂。介绍了公用事业公司选择低压膜的原因，以及传统膜处理和膜处理在各种问题上的比较，包括:原水质量；所需的混凝剂/聚合物水平；原木清除量的比较；资本成本；使用许可的空间；以及场地空间或占地面积的使用。文中给出了反对膜过滤的理由，以及传统处理和膜处理的成本比较。提供了试验装置的示意图。包括表格，如图所示。

In 2002, the Modesto Irrigation District set out on a program to expand their existing treatment works. This paper discusses the criteria used to evaluate and select low pressure membranes to expand the Modesto Regional Water Treatment Plant. Reasons why utilities are selecting low pressure membranes are presented, along with a comparison of conventional vs. membrane treatment on various issues including: raw water quality; level of coagulant/polymer required; comparison of log removals; capital costs; use of permitted spaces; and, use of site space or footprint. Arguments against membrane filtration are given along with a cost comparison of conventional vs. membrane treatment. A schematic of the pilot plant is provided. Includes tables, figure.
