Treatment Of Als Utilizing A Stem Cell Strategy

Abstract

An investigation studying the effectiveness of sulfide removal from groundwater by a variety of tray aerators was conducted and an empirical first-order mathematical model was developed that accurately predicted sulfide removal. Total sulfide, temperature, pH, and dissolved oxygen content passing through each tray were analytically determined in the field at several facilities. The derived model took the form of Cn = C0 (10-kn), in which k = (0.00248)(hydrogen ion [H+]) -0.397 (tray area)0.584 (flow)-1.17, n is the number of tray stages (tray levels) in the aerator, C0 is the sulfide content entering the distribution tray, and Cn is the sulfide concentration exiting aeration tray n. Sulfide removal was negatively affected as H+ decreased and flow increased but positively affected as the available tray aerator surface area increased. The empirical model demonstrated linear correlation (R2 = 0.875-0.962) when model projections were compared with analytically measured values, with an accuracy that ranged between 3.44 and 13.3%.
