A water recycling system, available as an option for the Vactor 2100 Plus sewer cleaner configured with the positive-displacement blower, reuses water already in the sewer to clean sewer lines, eliminating the need for clean water. The user-friendly system delivers uninterrupted sewer line cleaning, enabling public utility and contractor professionals to clean more wastewater and sanitary lines in less time, without stopping to refill the water tank. A five-stage filtration system combines settling, centrifugal separation and absolute filtration to 100-micron particle sizes, preventing any abrasive solids from entering the jetting system. With no moving parts in the body or tanks, there is never a need to enter the body or tanks to maintain system components. 800/627-3171; www.vactor.com; Booth 4239.
