DESIGN AND OPERATION

摘要

Filtration is the fundamental system in a water treament 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 shuld require the minimum captial, operation, and maintenance costs while providing maximum operational flexibility. A robust filter design should be based on knowledge, experience, and user feedback. should be based on knowledge, experience, and user feedback.This article provides practical guidance on the design of high-rate filtration systems.
