| Contents Notes |
Weak washwater from a pulp mill, evaporator condensate from the spent liquor recovery system, and paper machine white water effluents were treated over a 17 month period in a secondary treatment plant consisting of 2 aeration basins. One basin was equipped with two 75 hp aerators and the other with six 25 hp aerators. Piping was designed to permit series and parallel operation of the two basins, and provisions were made to recycle treated waste. Series operation was superior to parallel operation for the wastes treated. The two 75 hp aerators were much more efficient in both mixing and aeration capacity than the smaller 25 hp units. An 80% BOD reduction in the system was achieved at a loading of 2.2 lbs BOD/hp-hr equivalent to a daily load of 16,000 lbs BOD. Total operating costs are discussed. |
