This slide presentation outlines a study on the impact of water quality and comparative assessment of adsorbent treatment technologies for arsenic removal. The objectives of the study included: Evaluate Several Commercially AvailableAdsorbents;Contrast Adsorption of Arsenate, As(V),versus Arsenite, As(III);Identify Inhibitory Impacts of Water Quality; and, Define Adsorbent Properties and EstablishOptimum Process Conditions. The experimental approach included:Batch Tests forPreliminary Screening of Candidate Adsorbents, Selection of Non-Adsorbing Buffer,Kinetics (contact time), andIsotherms (absence of interferants); and,Intensive Testing of Selected Adsorbents for thePhysical-Chemical Properties of Adsorbents and Isotherms (presence of interferants), andNSF Challenge Water and Utility-Supplied Waters; and,TCLP/WET Tests. Includes tables, figures.
Keywords: Water Quality; Arsenic; Testing; Kinetics; Adsorption
