Technical and economical evaluation of a new anaerobic system for Lake Utopia Paper

Lake Utopia paper mill as part of the J.D. Irving, Limited (JDI) is located in Southern New Brunswick. The mill waste water treatment system is an integral part of its operation. The mill production has been increased dramatically over the last twenty years. The total BOD level in the waste water to treatment plant has also increased significantly with the increase of mill paper production. The other issue that the anaerobic plant is faced with is the build-up of calcium carbonate in the reactor sludge which occupies the reactor volume and decreases its efficiency. Due to these various reasons, this project is intended to provide the mill with the most efficient solution to its waste water treatment system among the possible options. So far installation of new reactors which is not sensitive to incoming suspended solids and can handle higher hydraulic loads of waste water is proposed.
