The impact of initial organic carbon concentration, powdered activated carbon (PAC)dose and type, contact time, coagulation and oxidation on the adsorption of natural organicmatter (NOM), as measured by total and dissolved organic carbon (DOC) and ultraviolet absorbance(UVA), was evaluated on seven raw water sources. Two models were developed based on theresults of four waters and applied to predict the results of three external waters. A simplerelationship between DOC fraction removal and UVA fraction removal was found to besuccessful in predicting DOC fraction removal. Three empirical models based on powdered activated carbon (PAC) type weredeveloped for predicting DOC removal by PAC as a function of initial DOC concentration, PACdose, and contact time. Includes 2 references, table, figures.
