"Monster" Upgrade Cuts Maintenance Over 75%

Merritt, BC—Public works and operations management at a conventional activated sludge wastewater treatment plant (WWTP) report reduction of routine maintenance time for screenings processing equipment by over 75% through the installation of a design upgrade.

The upgrade, an Auger Monster®, aided in restoring optimal BOD levels along with other benefits realized upon installation. The original version was installed in 1999 after the plant lost district landfill privileges, and whose performance had begun to slip due to wear. With key components now fabricated from stainless steel, it is also expected to provide significantly extended high-performance service life, while the plant concurrently pursues installation of separate, long-needed grit removal equipment.
