ASP-HDF® is a high rate activated sludge process (ASP) that works well even at high mixed liquor suspended solids (MLSS) concentrations with the help of the HUBER HDF® dissolved air flotation system. It is also ideal for reducing effluent treatment plant (ETP) footprint. For more information visit www.atehuber.com
