Title
Resolution to Approve the Purchase of Polymer from Polydyne Inc. for the Wastewater Treatment Plant, ITB-4386 ($218,800.00 per year estimated)
Memorandum
Your approval is requested to authorize the purchase of polymer (approximately 30,000 gallons) from Polydyne Inc. (Polydyne) for the City's Wastewater Treatment Plant (WWTP) for one year at an estimated cost of $218,800.00, and to authorize up to three one-year renewals by mutual agreement between the City and Polydyne.
The WWTP has two gravity belt thickeners and three dewatering centrifuges to improve the plant's ability to thicken and dewater biosolids for land application or landfill disposal. Biosolids must be conditioned with polymers to ensure functionality and optimal performance of the gravity belt thickeners and centrifuges, thereby enabling cost effective management of biosolids.
Several years ago, plant staff worked with vendors to test various polymers best suited to the WWTP's biosolids thickening and dewatering equipment. Based on these test results, staff advertised for two specific polymers under a previous Invitation to Bid, ITB-4178: SNF Polydyne, Clarifloc CE-1540 polymer and BASF Corp., Zetag 8846FS (US) polymer. Either of these two polymers can be used effectively in both the gravity belt thickeners and the dewatering centrifuges. Therefore, pricing was requested for the same two polymers under ITB-4386.
The following suppliers submitted bids in response to ITB-4386:
Polydyne Inc.
* SNF Polydyne, Clarifloc CE-1540 $0.795/lb., delivered
BASF Corp.
* BASF Corp., Zetag 8846FS (US) $0.808/lb., delivered
Staff reviewed the bids, compared them to ITB-4386 specifications and recommends that Polydyne Inc. be approved as the lowest responsible bidder to supply polymer at the WWTP for FY16.
Additionally, it is recommended that the agreement be extended for up to three one-year renewals at no increase in cost if the supplier and the City Administrator agre...
