MBBR-DAF System Drastically Reduced BOD And TSS Amounts Released Into Nearby Harbor

Ladysmith, BC is home to nearly 8,000 people on the western coast of Canada and has a history of coal mining, forestry, rail and marine industry. An existing wastewater treatment plant (WWTP) provided treatment to the town’s wastewater before discharging to the Ladysmith Harbor. The plant removed primarily particulate matter and suspended solids from the wastewater to be driven to a composting site. The existing system met some needs, but would not be able to achieve the future BOD and TSS effluent limits proposed to the town.
