Information on a full -scale Sequencing Batch Reactor waste treatment system
operating since 1998 on a 220-sow farrow to finish unit in Langley, BC.
The developmental work on this system was dont by the U.B.C. Department
of Bioresource Engineering and the BCMAFF Waste Management Engineer
during 1988 and 1989. The HPSFG monitored and made modifications to the
system from 1991 to 1003. This fact sheet presents a summary of the
system's design and treatment capability. For a full reposrt on the
system, contact Rick Van Kleeck, BCMAFF Resource Management Branch,
Abbotsford, BC.
The initial goal as the produce discharge quality effluent. However,
the system was never able to treat swine manure to this quality. As
well, waste discharge regulations changed during the course of the
project which increased the cost of discharging waste. A permit to
discharge for a 250-sow farrow-to-finish operation would now cost in
the range of $3500 per year. Because of this cost and beacuase most hog
operations have some land base, land application is probably the most
cost-effectve way to handle manure treated with this system.
