Resolution to Approve the Purchase of Polymer from Polydyne, Inc. for the Wastewater Treatment Plant ($229,500.00/year, Estimated)
Your approval is requested to authorize the purchase of polymer from Polydyne Inc. for the City's Wastewater Treatment Plant (WWTP) at an estimated cost of $229,500.00 for FY20 and FY21. The WWTP utilizes two gravity belt thickeners and three dewatering centrifuges to thicken and dewater biosolids for beneficial reuse through land application or disposal in a landfill during winter months. Biosolids are conditioned with polymers to ensure functionality and optimal performance of the gravity belt thickeners and centrifuges, which makes the biosolids acceptable for land application or landfill disposal and lowers the total expense of these management practices.

Plant staff worked with several vendors to test various polymers to ascertain characteristics best suited to the WWTP's biosolids thickening and dewatering equipment once this equipment was installed during capital improvements. After testing and deciding performance requirements, staff advertised for two specific polymers under ITB-4178: SNF Polydyne, Clarifloc CE-1540 polymer and BASF Corp., Zetag 8846FS (US) polymer. Either of the two polymers could be used in both the gravity belt thickeners and the dewatering centrifuges. Therefore, pricing was requested for the same two polymers under ITB-4579 with pricing being firm for two years.
The following suppliers submitted a response to ITB-4579:
Polydyne Inc
* Clarifloc CE-1540.............$1.02/lb., delivered
Solenis Corp.
* Zetag 8846FS (US) .........$1.13/lb., delivered

Staff reviewed the bids, compared them to ITB-4579 specifications and recommends that Polydyne, Inc. be approved as the lowest responsible bidder to supply polymer at the WWTP for FY20 and FY21 based on funds being available.

Additionally, WWTP staff recommended that the agreement be extended for up to three one year renewals...
