The materials of construction are 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 permanently sealed, bronze bushings with Buna O-ring seals. Other design features are an adjustable effluent weir depth and a top vented air release. The KLA Systems floating effluent decanter has a proven track record in the industry with over 20 years of successful operation.
