Leachate from bark landfills can be treated biologically by simply using the landfill itself as an anaerobic filter. This is accomplished by recycling the leachate-reintroducing it below the upper surface of the landfill. A requisite for the process is that the pH of the leachate remain approximately neutral. This can be accomplished by adding some lime sludge to the landfill as a pH controlling agent. Full-scale experiments indicate a BOD reduction of 90% without recycling. The noted effect with respect to COD is a reduction of 60%. The method is successfully operated in full-scale application. The investment costs involved are very low in comparison with alternative effluent treatment systems. (Refs. 4).
