Hydroxyl Systems awarded contract for Lakeview WWTP upgrade

Hydroxyl Systems will retrofit the activated sludge aeration basin during the first stage of the Lakeview WWTP IFAS upgrade project.

The Region of Peel, Ontario, has awarded a contract to Hydroxyl Systems Inc. for the supply of key equipment for the first phase of a major project at the 103 MGD Lakeview Wastewater Treatment Plant. The overall project will upgrade the capacity of the plant to 118 MGD and enhance treatment performance.

The contract award was the result of a competitive bid process, preceded by a comprehensive evaluation of various secondary treatment technologies. The evaluation determined that an upgrade utilizing a hybrid approach of fluidized fixed-film carriers and conventional activated sludge technology, generally referred to as IFAS, was ideal for the expansion of the Lakeview WWTP. This approach enables the municipal wastewater treatment plant to significantly upgrade treatment performance and capacity with minimal downtime or physical modifications to the existing plant.

The project entails the supply of Hydroxyl-Pac media, a proprietary suspended plastic biofilm carrier employed in Hydroxyl's unique Fluidized Fixed-Film and Return Activated Sludge (F3RAS) process. Hydroxyl Systems will also design and supply related equipment for the implementation of the technology at Lakeview WWTP.

Start-up of this project is scheduled for June 2003. Following a period of operation of the Hydroxyl-F3RAS process at Lakeview, the Regional Municipality of Peel intends to proceed with a full-scale hybrid retrofit of the entire wastewater treatment plant. The full-scale implementation of F3RAS technology at Lakeview would make it the largest facility utilizing the hybrid fluidized fixed-film and suspended growth treatment process in the world.

KMK Consultants Limited is providing engineering and project management services for the project.
