KLa Systems floating effluent decanters are used to draw clarified liquid from near the liquid surface of sequencing batch reactors and aerobic digesters. The design is both simple and rugged, constructed of Type 304L stainless steel for the weir, draw-off pipe, swing joint support, and stop supports.
The floats used are high-impact, UV stabilized polyethylene with closed cell polyurethane foam. The swing joint is cast iron with Ni-resist bushings with nitrile O-ring seals. Other design features are an adjustable effluent port depth and a top vented air release.
