Design Considerations for Producing High-Purity Recycled Water Using Membrane Technologies 利用膜技术生产高纯度循环水的设计考虑
发布日期: 2007-03-01
本幻灯片演示概述了一个试点测试项目,其目标是: 验证是否能够达到水质目标; 使用两个水源水评估性能; 描述反渗透(RO)废水的特征; 确定设计参数; 收集运营数据以制定保修计划 设计考虑;和 为东湾市政公用事业区(EBMUD)员工提供运营经验。微滤(MF)和反渗透系统的操作问题均与三级出水测试和二级出水测试相关。 从试点测试中得出的结论包括: 证明所需的水质(WQ)目标可以 使用MF/RO技术的met; MF/RO性能可接受二次泵 和三级污水; 三家反渗透膜供应商表示可以 符合标准; 在项目中有用的废物流特征 规划;和 初步测试的结果表明,这是可行的 将纳入设计的问题。包括表格、数字。
This slide presentation outlines a pilot testing project with the objectives of: verifying that water quality objectives can be met; evaluating performance with two source waters; characterizing the reverse osmosis (RO) reject; establishing design parameters; collecting operational data to develop warranty considerations for design; and, provide operational experience for the East Bay Municipal Utility District (EBMUD) staff. Operational issues for both microfiltration (MF) and RO systems are listed related to both tertiary effluent testing and secondary effluent testing. Conclusions drawn from the Pilot Testing included: demonstrated that required water quality (WQ) objectives can be met using MF/RO technologies; MF/RO performance acceptable with secondary and tertiary effluent; three RO membrane vendors indicated they can meet criteria; waste stream characteristics useful in project planning; and, results from the pilot testing identified operational issues that will be incorporated into the design. Includes tables, figures.
