Upgrading and evaluation for Lake Utopia Paper’sWaste Water Anaerobic Treatment Plant

Using simplified language understandable to a layperson, provide a general,
one-paragraph description of the proposed research project to be undertaken by the intern(s) as well
as the expected benefit to the partner organization. (Approx 150 words)
Lake Utopia paper mill as part of the J.D. Irving, Limited (JDI) is believed to be one of
the leading mills in preserving the environment. Specifically water quality is very
essential for the mill since the waste water of the mill is currently depleted to the
Letang estuary after treatment. 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
hydraulic loading rate of the UASB reactors is about 30 kg COD/m3/Day (20 kg
removable COD/rn3/D) which is almost double of max design value of 15 kg
COD/m3/D. UASBs are deSigned to receive influent of less than 500 ppm solids…..TBC
