过滤是水处理工艺序列中的基本系统，用于去除悬浮固体，包括隐孢子虫卵囊、贾第虫囊肿和寄生虫卵等微生物。为了限制成本，任何过滤器的设计都应该简单、可靠、易于建造和操作；而且，它应该要求最低的资本、运营和维护成本，同时提供最大的运营灵活性。稳健的滤波器设计应基于知识、经验和用户反馈。本文为高速过滤系统的设计提供了实用指导。包括24个参考文献、表格和图表。

Filtration is the fundamental system in a water treatment process train that removes suspended solids, including microorganisms such as Cryptosporidium oocysts, Giardia cysts, and parasite eggs. To constrain costs, the design of any filter should be simple, reliable, proven easy to build, and easy to operate; and, it should require the minimum capital, operation, and maintenance costs while providing maximum operational flexibility. A robust filter design should be based on knowledge, experience, and user feedback. This article provides practical guidance on the design of high-rate filtration systems. Includes 24 references, tables, figures.
