Sludge Buildup and Aerator Blockage Solved - Franklin Miller

The District of Kitimat, British Columbia, a pristine coastal community with 10,000 residents, is located at the head of the Douglas Channel and the Kitimat River. The area is a major salmon spawning corridor, supporting a large sports fishing industry. For both ecological and economic reasons, any facility discharging wastewater into the river must be mindful of strict discharge regulations. No one is more aware of this than the management of the Kitimat Wastewater Treatment Plant.

Recently, the plant, which treats 2.6MGD and handles peak flows of 7.3 MGD, was faced with an emergency upgrade. A barminutor, installed in the 1970’s as a bar screen and grinder, had rusted and developed holes, allowing rags, wood, rocks and other debris to pass through unimpeded. The debris not only caused blockages and clogs in the aerators but also contributed to the build up of sludge in the lagoon. The facility’s management was determined to install a more efficient system and end the chronic problems. After carefully reviewing their options, they chose the Dimminutor® Turbo Design Channel Disintegrator from Franklin Miller (USA).
