在缺水地区，淡化含盐地下水 可以代表水资源公用事业的重要替代资源。 使用反渗透和纳滤的高压膜 被认为是一种可行的海水淡化技术。 尽管新的膜正在迅速被引入 市场上，没有通用的、系统的评估协议 他们的表现。开发这样一个协议将允许实用程序 使膜筛选程序标准化，最终受益 制造商和公用事业公司。本文介绍 一种逐步试验新一代产品的方法 膜。建议的步骤包括基本数据收集、比较 中试，优化中试，膜 尸检和可行性分析。进行了试点测试 根据该协议，性能得到了明显改善 在已建立的膜和新膜之间- 一代 膜测试还表明，新膜 大大提高了操作压力，这可能 从而大大节省运营成本。包括18个参考文献、表格、图表。

In water-scarce regions, desalinating brackish groundwater can represent an important alternative resource for water utilities. High-pressure membranes that use reverse osmosis and nanofiltration are recognized as a viable desalination technology. Although new membranes are being rapidly introduced into the market, there is no general, systematic protocol for evaluating their performance. Developing such a protocol will allow utilities to standardize membrane-screening procedures, ultimately benefiting the manufacturers as well as the utilities. This article presents a step-by-step approach to pilot-testing the new-generation membranes. The proposed steps are basic data collection, comparative pilot-testing, optimization pilot-testing, membrane autopsy, and feasibility analysis. The pilot-testing conducted according to this protocol showed clear performance improvements between an established membrane and a new-generation membrane. The testing also demonstrated that the new membranes have greatly improved operating pressures, which could lead to substantial operational cost savings. Includes 18 references, tables, figures.
