BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities issued Bid 21-252, seeking a qualified vendor to supply liquid cationic emulsion polymer for use at the City's Springbrook Water Reclamation Center (SWRC). The liquid cationic emulsion polymer is used to dewater the residual solids from the wastewater treatment process.
As part of the bid process, qualified polymer vendors' products were tested at full plant scale conditions and evaluated for optimum performance. The performance testing established agreed upon representative dosages to accomplish required results per the Utilities' specifications for centrifuge dewatering. Vendors' dosages were determined as a prerequisite prior to the bid cost numbers being submitted.

1 The bid equalization factor is the dollar value of reduced disposal costs associated with the polymer vendor's product.
The bidding criteria is based on the price per pound of polymer needed to produce up to 5,200 dry tons of biosolids for land application. For bid comparison purposes, a bid equalization factor is calculated to give credit for polymers, which can produce a drier cake resulting in a lower volume of biosolids for disposal. Although Solenis has a higher bid equalization factor, Polydyne was able to meet specifications at a lower polymer dosage and a lower unit price per pound....
