Abstract
In order to improve the anaerobic digestion process of salty cheese wh ey, the effects of various doses of surfactants: Tween 80, Triton-X-10 0, Tegopren 3022, sodium lauryl sulphate and Cetrimide, have been stud ied in an upflow fixed film bioreactor. Among these, sodium lauryl sul phate showed a 70% increase in gas production with a higher methane co ntent (77%) and improved biodegradation. (C) 1998 Elsevier Science Ltd .
