Membrane Systems Planning and Design

Abstract

The purpose of this chapter is to provide the basic information on the use of membrane filtration and application of the technology in the design of potable water facilities. The main issues involved in the planning and design of membrane systems are covered: pilot testing; the considerations that influence system design and operation including operational unit processes, system design considerations, and residuals treatment and disposal; and the initial start-up phase which must be completed prior to placing the system into service and actual water production. The initial start-up phase is a critical step in the successful installation of a full-scale membrane filtration system and thus is an essential consideration in the facility planning and design process. This phase includes such tasks as initial system flushing and disinfection, system diagnostic checks, membrane module installation, integrity testing new equipment, and operator training, all of which must be completed prior to placing the system into service.
