Document Description
Palo Alto Research Center Inc. (PARC) will demonstrate their Hydrodynamic Separation (HDS) technology at a wastewater treatment plant in Sunnyvale. The HDS is a compact, highly modular particle separation technology to separate the majority of the suspended solids prior to the activated sludge process (ASP), effectively reducing the energy needed for aeration and allowing an alternative when considering plant expansion. These harvested suspended solids are inherently more difficult to dipest by ASP due to slower mass transfer than soluble organics. However, they cost less energy to dewater than sludge and are a great souces of carbon for anaerobie digestion to produce even more methane, further driving a plant toward being energy neutral.
