反渗透脱盐（RO）是一种重要的膜技术，适用于淡水资源丰富的地区 这是有限的。使RO有效运行的关键之一是提供足够的 脱盐过程的预处理。本文的目的是评估 通过试点研究，采用常规水处理工艺处理海水。具体来说 本文重点讨论了过滤级数、颗粒介质结构和混凝剂剂量的影响。课程包括: 原水水源；中试工厂描述；过滤介质配置；混凝剂剂量评估；介质设计对过滤水质的影响；过滤成熟时间；过滤速率对过滤水质和产水量的影响；单级和两级过滤的比较。包括表格、数字。

Desalination by reverse osmosis (RO) is an important membrane technology for areas where freshwater is limited. One of the keys to making RO operate in an efficacious manner is to provide adequate pretreatment for the desalination process. The objective of this paper is to evaluate the efficacy of conventional water treatment processes for treatment of seawater through pilot studies. Specifically, the paper focuses on the impact of number of filter stages, granular media configuration and coagulant dose. Topics covered include: raw water source; pilot plant description; filter media configurations; coagulant dose evaluation; impact of media design on filtered water quality; filter maturation time; impact of filtration rate on filtered water quality and water production; and, comparison of single and two-stage filtration. Includes tables, figures.
