Abstract

Pulp and paper industries generate highly-colored wastewaters, the color of which is not removed by conventional biological treatment. As a result, the persistent color of the wastewater can potentially disrupt the aesthetic appearance of the recieving stream as well as releasing potentially toxic compounds to the environment. Coagulation and flocculation is a chemical treatment practiced to remove color from pulp and paper mill wastewaters. The main focus of this work was to study the color removal efficiency of coagulation/flocculation treatment on a specialty pulp and paper mill wastewater located in the State of Tennessee. In this regard, the effect of coagulant, coagulant aid, and flocculent dosages as well as the wastewater pH and temperature on color removal process were examined. Furtheremore, bentonite clay and powdered activated carbon (PAC) effectiveness for color removal were tested.
