AWWA ACE90035

This study evaluated the alternatives to manganese removal by continuously regenerated greensand at a full-scale treatment plant in Columbus, Indiana. Specific objectives addressed in this study were to: (1) evaluate alternative media configurations for removal of particulate iron and manganese with respect to volume of water treated before metals breakthrough and rate of head loss accumulation; (2) investigate the applicability for removing soluble manganese, Mn(II), by adsorption and oxidation onto the surface of oxide-coated media; (3) evaluate the performance of naturally oxide-coated media versus precoated media commercially available; and (4) develop a mathematical model to predict (a) the removal profile of soluble manganese by adsorption/oxidation onto the surface of oxide coated media in the presence of free chlorine and (b) the exhaustion profile of the manganese adsorption capacity in the absence of free chlorine.
