The PAT 949 combination truck from Polston Applied Technologies removes sand and grit from wastewater treatment plants, large-diameter lines, digesters and lift stations without shutting down the plant service. It combines vacuum, jetter and a down-hole pump system that cleans systems in submerged conditions while they remain in operation. It has a 49-foot hydraulic knuckleboom crane that moves across a 22-foot radius and can pump water up to 2,500 gpm. The end result is material that is paint-filter dry and can be taken straight to the landfill. 844/765-7866; www.polstonprocess.com.
