1 The bid equalization factor is the dollar value of reduced disposal costs associated with the polymer vendor's product.
2 The net cost is equal to the bid amount minus the bid equalization factor.
In the procurement of liquid cationic emulsion polymer, the Water Utilities takes into account how much polymer is needed to dewater the residual solids which includes disposal costs of the residual solids.
The bidding criteria is based on the price per pound of polymer needed to produce 4,000 dry tons of residual solids. The net cost of the vendor's proposal includes the vendor's bid price less the Bid Equalization Factor which evaluates the effectiveness of the polymer in dewatering the solids, as well as how much residual solids are produced and the costs of disposal.
Nalco Chemical's base pricing was slightly higher than BASF. However, Nalco's product was more efficient (requiring less polymer) to dewater the same amount residual solids and will produce l...
