PROJECT: PILOT SCALE ASB TREATABILITY WITH CHEMICAL ADDITION FOR REMOVAL OF TAINTING PROPENSITY FROM PULP MILL EFFLUENT
 LOCATION: Kitimat, B.C.
OWNER: Eurocan Pulp & Paper Company
DESCRIPTION: The treated effluent from this unbleached kraft mill causes tainting to eulachon runs. The objective of the pilot program was to investigate upgrading options to reduce the tainting propensity of the treated effluent. A trailer-mounted two and three cell aerated stabilization basin (ASB) was operated for about nine months under controlled conditions involving short and long retention, high and low temperatures and with and without hydrogen peroxide feed. The findings of the study formed the basis for recommendations to upgrade the existing treatment system.
ROLE: Specialist sub-consultant, pilot plant design, and operation.
