Treatment Shaft Technology - Brochure

Automated capture and treatment of large combined sewer overflows (CSOs) in a compact structure. Minimal head loss, primary settling, skimming, fine screening, and disinfection–all in one unit. Process Description: Process Wastewater Technologies and Applied Engineering Technologies (AET) have partnered to develop a fully-automated, patented* vertical treatment shaft process for CSO control systems. The technology provides disinfection contact time, vessel flushing, air venting, odor control, surge control, skimming, settling, and fine screening in a compact structure suited for urban sites. The system provides a cost effective alternative to basins, tunnels, and sewer separation. CSO treatment shafts can be built using a variety of construction methods, including: slurry wall, diaphragm wall, sinking caisson, tangential pile, secant pile, and sheet pile.
