Disposal of excess sludge from wastewater treatment is a growing problem in Ireland and across Europe. Sludge processing, handling and disposal costs comprising a significant portion of treatment plant operating costs. Technologies to reduce sludge generation have been found to be expensive,require addition of toxic chemicals or significant changes to plant operation. This project demonstrates an adaptation to conventional activated sludge treatment for redcued sludge generation. A two channel lab scale pilot plant was demonstrated with synthetic and real wastewater. Numerous operation problems were encountered during on-site demonstration whih limitted useful data obtained. Longer term study of this process is warranted to verify suggested trends of reduced biomass generation at pH 6.0-6.2. Slower biomass build up was seen under acid dosing but this was accompanied by solids losses in effluent. Larger scale demonstration could overcome some of the settling and solids loss problems which are amplified at smaller scale. Further work is needed to best incorporate this process into an effective and reliable wastewater treatment engineering solution.

A Masters Thesis is also attached to this resource "Design of a twin-lane lab scale activated sludge plant" by Mr. Eric McGeough who was supervised by Dr. Prunty.
