Dissolved organic matter (DOM) and pH are important factors affecting heavy metal uptake by sludge particulates. Copper(II) and Nickel(II) uptake behavior by primary and secondary sludge particulates was studied under various pH and DOM conditions. A three-variable model, incorporating effects of pH and DOM, was developed to describe heavy metal uptake. Results show that heavy metal uptake by sludge particulates can be better described by the three-variable model than by the modified Langmuir model in a wide pH range.
