本文介绍了一系列独特的试验台和中试规模的结果 在南加州进行的测试，旨在确定预处理对 海水反渗透（SWRO）性能。两种最常用的预处理方法 SWRO方案——常规预处理（混凝/过滤）和膜过滤 进行了评估。为优化混凝剂的投加量，进行了小型试验 常规预处理。基于批处理内部流程修改的台架规模设置 DiGiano等人（2000年）开发的循环膜试验（BAIReMT）设计用于 筛选反渗透膜。 此外，还对海水进行了粒度分级，并 利用上述装置进行了反渗透污染实验，以确定各种因素的影响 反渗透（RO）污染的粒度分数。这些粒度分数可能与不同级别的 通常用于海水反渗透的预处理。试验分两个阶段进行: 第一阶段测试侧重于预处理评估，而第二阶段则侧重于反渗透评估。 在第一阶段，评估了两种过滤器配置和微滤作为预处理 策略。在中试的第二阶段，两个反渗透系统同时运行，以 在不同的操作条件和水源类型下，评估预处理对反渗透污染的影响。包括10个参考文献、表格和图表。

This paper presents the results from a unique series of bench and pilot scale tests conducted in Southern California, designed to determine the effect of pretreatment on Seawater Reverse Osmosis (SWRO) performance. The two most commonly used pretreatment schemes for SWRO - conventional pretreatment (coagulation/filtration) and membrane filtration were evaluated. Bench scale tests were conducted for optimization of coagulant dose for conventional pretreatment. A bench scale setup based on a modification of the Batch Internal Recycle Membrane Test (BAIReMT) developed by DiGiano et al (2000) was designed for screening RO membranes. Additionally, size fractionation of the seawater was conducted and RO fouling experiments were performed using the above setup to determine the effect of various size fractions on reverse osmosis (RO) fouling. These size fractions can be related to different levels of pretreatment commonly utilized for seawater RO. Pilot testing was conducted in two phases: Phase I testing focused on pretreatment evaluation, while Phase II was focused on RO evaluation. During Phase I two filter configurations and microfiltration were evaluated as pretreatment strategies. In the second phase of pilot testing two RO systems were operated simultaneously to evaluate the effect of the pretreatments on RO fouling under different operating conditions and source water types. Includes 10 references, tables, figures.
