Removing Humic Substances by Chemical Treatment and Adsorption
Alum coagulation and lime softening exhibited variable effectiveness for removing the total organic carbon (TOC) associated with humic substances in water supplies. Pretreatment with alum or lime also affected the subsequent adsorption of TOC by granular activated carbon, with alum coagulation generally improving overall adsorbability. The effectiveness of pretreatment for removing TOC and for altering the adsorption characteristics of residual humics appears to depend on the source and type of the humic material.
