PT. Indofood CBP as one of the food industry that produces ingredients as its product does not miss from sludge treatment issues. The sludge inflicts troubles on the environment and PT. Indofood CBP, since there is no effective handling and processing. Extracellular Polymeric Substances (EPS) as one of alternative sludge treatment. By varying volume of the sludge: 300 gr, 400 gr, and 450 gr, and mass of the EPS: 350 gr, 400 gr, and 450 gr DW, thus it could be indicated that the more EPS are given and the less amount of sludge volume then a greater degradation of sludge. Obtained data shows the reduction of COD is 65,16% in reactor 1, 69,15% in reactor 2, 81,78% in reactor 3, 53,19% in reactor 4, 57,85% in reactor 5, 65,82% in reactor 6, 44,55% in reactor 7, 45,88% in reactor 8, 47,21% in reactor 9, 36.57% in control reactor. And the reduction of BOD is 59,29% in reactor 1, 60,62% in reactor 2, 65,04% in reactor 3, 51,77% in reactor 4, 52,65% in reactor 5, 55,75% in reactor 6, 37,61% in reactor 7, 39,82% in reactor 8, 44.69% in reactor 9, 35,84% in control reactor.
