Title
Resolution to Approve the Purchase of Polymer from BASF Corporation for the Wastewater Treatment Plant, Bid No. ITB-4539 ($193,070.00 estimated)
Memorandum
Your approval is requested to authorize the purchase of polymer from BASF Corporation for the City's Wastewater Treatment Plant (WWTP) at an estimated cost of $193,070.00 for FY19.
The WWTP utilizes two gravity-belt thickeners and three centrifuges to make biosolids suitable for beneficial reuse through land application during the non-winter months, and for disposal at a landfill during the winter. Biosolids must be conditioned with polymers to ensure functionality and optimal performance of the centrifuges and gravity belt thickeners, and to thereby lower the total expense of the process.
Plant staff worked with several vendors to test various polymers to ascertain characteristics best suited to the WWTP's biosolids processing equipment. The results of these tests indicated that two polymers, SNF Polydyne Clarifloc CE-1540 and BASF Corporation Zetag 8846FS (US) are the most effective choices. Pricing for both polymers was requested under Bid No. ITB-4539, and the following supplier submitted a response:
* BASF Corporation, Zetag 8846FS (US) .........$0.898/lb., delivered
Staff reviewed the bid, compared it to ITB-4539 specifications and now recommends that BASF Corporation be approved as the lowest responsible bidder to supply polymer to the WWTP for FY19. Staff also seeks authority to extend the agreement for a year up to three times at the same price, should funding be available and should BASF Corporation and the City Administrator agree.
Funds to finance this purchase are included in the approved FY19 WWTP Operation and Maintenance budget for the Sewage Disposal System.
