Major mixer, pump retrofit for new Utah bioreactors completed

Sponsored by


June 30, 2014 -- Landia has completed a successful pump and mixer retrofit at the newly-expanded, 30-million-gallons-per-day (MGD) wastewater treatment facility (WWTF) in American Fork, Utah, that has transformed eight existing oxidation ditches into new high-rate activated sludge bioreactors with biological nutrient removal, solids dewatering and ultraviolet (UV) disinfection.

A total of 48 Landia submersible mixers and 16 Landia axial flow pumps are achieving complete mixing and nitrate recycling in a new activated sludge process at the site run by the Timpanogos Special Service District, close to Utah Lake, which serves 10 cities in the region.

The newly-expanded WWTF in American Fork, Utah, where Landia has completed a successful pump and mixer retrofit.


Working in close conjunction with leading Utah and Idaho engineering firm Bowen Collins & Associates, Inc., to select long-lasting equipment that would give optimum performance, mixers from Landia now mix the sludge in the anaerobic and anoxic tanks, whilst internal Landia Recycle Pumps send nitrified mixed liquor from the aeration basin onto the anoxic tanks.

Operating at low propeller speed, each Landia mixer is equipped with large surface area propeller blades to ensure gentle treatment of the activated sludge. Likewise, the axial flow pumps operate on variable frequency drives (VFD), by which each pump's flow rate is optimized for the required nitrate recycle rate.

The $77-million project, which also features a new headworks and influent pump station, has increased the capacity of the treatment plant from 18.3 mgd to 30 mgd.
