Upgrade to primary and secondary clarifier tanks and blowers

completed

Modify and improve the Peterborough Waste Water Treatment Plant (WWTP) process by replace aging mechanical structures in the 4 older primary and 4 secondary clarifiers (total 8 tanks) to improve sludge management; repair and seal concrete in these same tanks as needed to reduce tank failure risk; replace aging centrifugal blowers with high efficient turbo blowers to improve hydro consumption; conduct an air flow study to identify air flow bottle-necks; clean air diffusers in aeration basins to increase oxygen transfer ability to optimize new blower performance and aeration basin performance.
