Fine Screen Prevents Trash from Entering Canadian Wastewater Lagoon
The new system was installed in 2008
The city of Revelstoke, located along the Columbia River in British Columbia, boasts a growing ski resort and one of the world's best heli-skiing destinations. The scenery of the neighboring Selkirk and Monashee mountains belies Revelstoke's growing population. In 2007, Revelstoke had more than 7,000 residents, and hosted thousands of winter sport enthusiasts at Revelstoke Mountain Resort.
A Growing Problem
Since the resort opened in 2005, sewage flows through the treatment plant increased dramatically. A Channel Monster sewage grinder had operated at the treatment plant since 1998. It was in one of three channels, meaning at peak flows there was only a 33% chance solids would be ground to pieces before entering the lagoon. This new influx of solids left operators struggling to skim floating debris off the lagoon. By 2006, it was obvious a screening system was needed.
Happy with the service and performance of their Channel Monster, the city sought a solution from JWC Environmental (JWCE) and their distributor, Jelcon Equipment.
Jelcon provided information about a Monster Separation System, which combines a high-flow Finescreen Monster with a Screenings Washer Monster. The intermittently-running fine screen captures rags, trash and plastics and transports debris up the screen and into a dual-shafted grinder—the first step of JWCE’s patented Screenings Washer Monster system. Ground solids are transported by an auger, washed and forced up a tube to produce dry, easily bagged solids ready for the landfill. The Monster Separation System was installed in 2008, during a major headworks upgrade.
A Successful Installation
Revelstoke operators Steve McKnight and Reinie Bittner are pleased with the changes the Monster Separation System brought to their day-to-day operations.
When asked about the biggest improvements, McKnight said, "It’s much safer. We used to be hanging around the lagoon with a pool skimmer and bagging by hand."
The operators were also pleased with the system’s low maintenance requirements. This includes periodic visual inspections of the brushes and taking the bagged screenings to landfill.
The bagging system uses a long continuous bag, which only needs to be replaced "once a year, around Christmas time," Bittner said. Both operators were happy with the level of service JWCE and their distributor, Jelcon Equipment, have provided.
Bittner remarked service "has been good," and McKnight added, "It's what we'd like from all our reps."
