MODELING SOLUBLE MANGANESE REMOVAL BY OXIDE-COATED FILTER MEDIA

Mathematical models were developed to predict design and operational c onditions needed to implement oxide-coated media as a treatment proces s for soluble manganese removal. Two separate models were developed to predict the continuous removal of soluble manganese in the presence o f free chlorine (continuous regeneration model). and the eventual brea kthrough of soluble manganese without oxidant addition (intermittent r egeneration model). Each model was derived from chemical reaction, mas s balance, or isotherm equations and was further developed by a sensit ivity analysis and parameter estimation. Model verification involved r eview of independent research studies regarding soluble manganese remo val.
