| PROJECT: BCTMP MILL EFFLUENT TREATMENT
PLANT |
| LOCATION: Slave Lake, Alberta |
| OWNER: Slave Lake Pulp Corporation |
| DESCRIPTION: A greenfield 130,000
ADMT BCTMP mill using Aspen as wood furnish. The high strength
effluent, with a BOD5 strength of up to 6,000 mg/L (35 t/d) and
flow of 6,300 m3/d, is treated by a five day extended aeration
activated sludge process. This represented the first application
of this treatment technology on Aspen BCTMP effluent. The treatment
process includes flow equalization, cooling, fine screening,
dissolved air flotation, nutrient addition, four activated sludge
basins with flexible flow configurations, three 1,500 HP single
stage centrifugal blowers, rotary screen sludge thickeners, sludge
screw press and DCS control. |
