Full Description

Membrane filtration processes, microfiltration and ultrafiltration, are nowmainstream filtration processes competing with conventional technologies. Waterproviders are selecting membranes because of their lower cost trends and superiortreatment performance of a wide variety of source waters. Many new large capacitymunicipal projects are now under construction in North America, and even more arebeing planned. Water utility decision makers require meaningful and accurateconstruction and operation and maintenance (O clean-in-place (CIP) equipment; feed or permeate pumps;backwash pumps; blowers; instrumentation and control equipment; and, tanksassociated with cleaning and backwashing. While the cost of the membrane modulesis proportional to the design capacity and flux of the system, the cost of theother components has a significant economy of scale.
