An optional water recycling system for the Vactor 2100 Plus sewer cleaner reuses water already in the sewer to clean sewer lines, eliminating the need for clean water. 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. It can help municipalities save thousands of gallons of freshwater, improve efficiencies, reduce costs and promote sustainability. The system can also increase operator productivity up to 100 percent, enabling operators to clean twice the number of lines. 815/672-3171; www.vactor.com; Booth #5050.
