Abstract

Integrating Electro-Dewatering into Advanced Biosolids Processing Where Does It Make Sense?Electro-dewatering applies a continuous direct electric current to a layer of partially dewatered biosolids cake through a cathode and an anode, thereby employing electrophoresis and electroosmosis to increase both the rate and extent of further dewatering — percent solids in excess of 40% are readily attainable. No polymer addition is required. Pathogen reduction to Class A levels is...Author(s): Ralph EschbornMohammad Abu-OrfDany Sarrazin-SullivanSourceProceedings of the Water Environment FederationSubjectSession 2: Thickening and DewateringDocument typeConference PaperPublisherWater Environment FederationPrint publication date Jan, 2011ISSN1938-6478SICI1938-6478(20110101)2011:4L.141;1-DOI10.2175/193864711802863030Volume / Issue2011 / 4Content sourceResiduals and Biosolids ConferenceFirst / last page(s)141 - 153Copyright2011Word count471Subject keywordsElectro-dewateringBiosolidsClass ADewateringSolids ProcessingSludge Beneficial Reuse
