About this file
This is an Invitation for Pre-Approval issued by the Long Beach Public Utilities Department for polymer-blend coagulant products for groundwater treatment. The document solicits pre-approval of products in anticipation of future competitive procurement, with only successfully pre-approved products eligible for consideration in subsequent bid solicitations. Vendors may submit a maximum of two polymer-blend products, with each submission requiring one 1,000-milliliter sample, current NSF/ANSI/CAN 60 certification documentation, a current Safety Data Sheet, product technical data sheets with molecular weight distribution information, and a DOT-approved return shipping container with prepaid return shipping label. Submissions must be delivered to Skip Fulton, Manager of Water Treatment at the Groundwater Treatment Plant, 2950 Redondo Avenue, Long Beach, California 90806, no later than 3:00 p.m. PDT on Tuesday, December 8, 2026. Sample testing is scheduled to begin in December 2026 and will be performed solely by Long Beach Public Utilities Department staff.
The pre-approval evaluation process consists of two phases: initial bench-scale jar testing to determine optimum polymer-blend dosage in combination with ferric chloride, followed by pilot-scale testing for products achieving a minimum of 30 percent total organic carbon removal. Products selected for pilot testing must provide an additional 4,000 milliliters of product. Pilot plant performance criteria include finished water color of 5 color units or less, finished water turbidity below 0.10 NTU, at least 35 percent TOC removal, and filter headloss below 4 feet per 24 hours. Bid evaluation will consider polymer-blend cost per acre-foot treated, ferric chloride cost per acre-foot treated, sludge handling and disposal cost per acre-foot treated, and pH adjustment chemical cost per acre-foot treated. Previously approved products from five vendors—Kemira, Sweetwater, General Chemical, Summit, and Polydyne—are listed for reference.

| Polymer‐Blend | Coagulants | for | Groundwater | Treatment |
The Long Beach Public Utilities Department is soliciting polymer-blend coagulant products for pre-approval in anticipation of future competitive procurement. Only products successfully completing this pre-approval process will be eligible for consideration in the subsequent bid solicitation.
Product Submission Requirements Vendors may submit a maximum of two (2) polymer-blend products.
Provide one (1) 1,000-mL sample of each product submitted.
Provide current NSF/ANSI/CAN 60 certification documentation.
Provide a current Safety Data Sheet (SDS).
Provide product technical data sheets and molecular weight distribution information.
Provide a DOT-approved return shipping container and prepaid return shipping label.
Deliver To: Skip Fulton, Manager of Water Treatment, Groundwater Treatment Plant, 2950 Redondo Avenue, Long Beach, CA 90806.
Submissions must be received no later than 3:00 p.m. PDT on Tuesday, December 8, 2026.
Pre-Approval Evaluation Process
Sample testing is scheduled to begin in December 2026. All testing and evaluations will be performed solely by Long Beach Public Utilities Department staff.
The following information represents historical groundwater quality ranges observed during plant operations and is provided to assist vendors in evaluating product suitability.
Parameter Historical Range Color 9-61 CU Turbidity 0.10-0.95 NTU Total Organic Carbon (TOC) 0.76-3.60 mg/L pH 8.2-8.6 Total Alkalinity 137-162 mg/L as CaCO3 Temperature 21.7-30.0 °C
Desired Polymer Molecular Weight Distribution:
Fraction Requirement >10,000 amu 32% min. - 70% max.
1,000-10,000 amu 15% min. - 58% max.
<1,000 amu 10% min. - 15% max.
1800 E. Wardlow Road, Long Beach, CA 90807 | 562.570.2300 | LBUtilities.org
All products will be evaluated using the same groundwater blend and testing protocol.
Initial screening will consist of bench-scale jar testing to determine the optimum polymer-blend dosage in combination with ferric chloride.
Anticipated jar-test source-water conditions are approximately 40-45 CU color and 2.0-2.5 mg/L TOC. These values are provided for informational purposes only and are intended to represent typical testing conditions. Actual source-water quality may vary within the historical ranges shown above.
Products achieving a minimum of 30 percent TOC removal under optimized jar-test conditions will advance to the pilot-scale testing phase. Vendors with products selected for pilot testing shall provide an additional 4,000 mL of product upon request.
Pilot Plant Performance Criteria Parameter Target Finished Water Color ≤ 5 CU Finished Water Turbidity < 0.10 NTU TOC Removal ≥ 35% Filter Headloss < 4 feet per 24 hours
Additional operational parameters, including sludge production, pH impacts, and chemical demand, will be monitored and considered as part of the overall evaluation. Long Beach Utilities reserves the right to consider overall treatment performance, operational impacts, and cost effectiveness when determining product acceptability.
Bid Evaluation Methodology Polymer-blend cost per acre-foot treated Ferric chloride cost per acre-foot treated Sludge handling and disposal cost per acre-foot treated pH adjustment chemical cost per acre-foot treated
Previously Approved Products Kemira: PAX-XL-37A3, PAX-XL-39A3 Sweetwater: CP8805B, CP8807B General Chemical: Clar-ion A415P Summit: 803-B Polydyne: PRX-B29
