The Resort Municipality of Whistler (RMOW) is inviting experienced, reliable, and qualified Suppliers to
provide a proposal for the supply and delivery of dewatering flocculating agent polymer to the RMOW
Wastewater Treatment Plant (WWTP).

The RMOW’s WWTP treats wastewater from Whistler using an enhanced biological phosphorus
removal (EBPR) process. Within the solids handling building, the plant has one Dissolved Air Flotation
(DAF) tank for waste-activated sludge (WAS) thickening and two centrifuge dewatering units. The WAS
from the two bioreactors is pumped to the DAF for thickening. Polymer is added to the WAS before the
DAF tank to enable higher thickening and improve solids capture performance. The thickened waste-activated sludge (TWAS) from the DAF tank is pumped to one of two TWAS storage tanks. Additionally,
Primary sludge is removed from the Primary Sedimentation Tanks and then pumped to a Primary
Sludge storage tank located adjacent to the TWAS tanks. The TWAS and Primary sludge are blended at
an operator-designated ratio. Prior to sludge entering the centrifuges, polymer is added to bulk the solids
and improve the separation of solids and liquid. The plant stores liquid polymer agent in 1,040 kg
Intermediate Bulk Containers (IBC). The polymer is injected using the ProMinent ProMix S & M Polymer
Blending Systems. Polymer is gravity-fed to the polymer dosing system, discharged to the DAF tank,
and centrifuged at operator-adjusted rates.
