ATTACHMENT A: Cationic Polyacrylamide

SPECIFICATIONS

Polymer described as Cationic Polyacrylamide dispersed in light mineral oil equal to ZETAG 7879.

Intended Use and General Description:

1. The City of Redmond Wastewater Division uses approximately thirteen thousand three hundred pounds (13,300 lbs.) to twenty-two thousand eight hundred (22,800 lbs.) of liquid Cationic Polyacrylamide annually for the dewatering of Biosolids, depending upon the supplier.

2. Polymer is purchased in two thousand two hundred (2200) lb. totes and delivered to a loading dock at the Water Pollution Control Facility (WPCF) located at 3100 NW 19th St Redmond OR 97756. The loading dock at City of Redmond’s WPCF is not of standard height and requires all delivery trucks to have a liftgate for proper delivery of all products.

3. The estimated Polymer quantity required/usage is summarized in the table below. These quantity estimates are not guaranteed and there shall be no minimum or maximum yearly purchase obligation.

They are used for evaluating bidder’s ability to meet chemical demands and price estimates. Contracts for delivered product may be divided between up to (2) suppliers or awarded to a single contractor at 100% based on the responses to this ITB.

SPECIFICATIONS:

QUALITY: The polymer delivered shall meet or exceed applicable provisions of the American Water Works Association Standard for Cationic Polyacrylamide and all subsequent revisions or corrections.

City of Redmond WPCF may require an affidavit of compliance with all applicable requirements of the standard. Failure to provide such affidavit within a reasonable time of the request shall be cause for rejection of the bid or termination of the supply contract. The proposal should also include a safety data sheet (SDS) and the most recent representative chemical analysis report of the polymer to be supplied, as prepared by a reputable outside laboratory or bidder’s in-house laboratory if ISO-certified. These sheets should be representative of the chemical used for the completed bid schedule page. A Certificate of Analysis from each manufactured batch shall accompany each shipment of polymer. These batch analyses shall include but are not limited to the following: 1) Product Name, 2) Batch Identification, 3) Specific Gravity, 4) % Cationic Polyacrylamide by weight, 5) Date of batch.

PHYSICAL REQUIREMENTS & SPECIFICATIONS:

1. The polymer supplied must be dispersion/emulsion type only and readily and completely soluble in water. The polymer must maintain ninety percent (90%) effectiveness for up to six (6) full months after delivery. Physical and chemical characteristics shall not change during this period.

The polymer materials in both concentrated and diluted forms shall be classified as non-hazardous material for shipping and use under applicable standards, and shall not require special handling, nor shall they pose hazards to employees working with them. The polymer supplied must have low toxicity with respect to contact with the skin and eyes and to accidental ingestion or inhalation. First aid or other suggested medical treatment procedures for this product must be furnished by the supplier prior to delivery or first shipment. The material shall not be corrosive to the equipment. The vendor shall be responsible for any equipment necessary to make their polymers compatible with the existing storage and handling facilities. All polymer containers will be stamped with the date of production and an expiration date.

2. The polymer used shall cause efficient and effective conditioning and flocculation of municipal sludge which is applied to the dewatering process used by the City. If a polymer is selected other than current polymer used by the City, the City reserves the right to require a thirty (30) day trial period for a performance comparison on various feed sludge conditions that might occur in the digestion process. Upon evaluation of the performance of the polymer, the City reserves the right to reject or accept the proposed polymer based on the ability to perform under various sludge conditions. If any shipment of polymer is proven to be more than five percent (5%) less effective than the control sample, the City reserves the right to reject that shipment. The rejected material shall be removed by the supplier at the supplier’s expense. The supplier shall then replace the rejected material with satisfactory material or credit to the city for the full delivered price of the rejected material.

3. Upon request, vendor shall provide technical assistance throughout the contract period for improving the performance and utilization of their product. Vendor will be required to conduct testing, under the Wastewater Division Treatment Supervisor’s supervision, to ensure compliance with the requirements when materials are deemed unsatisfactory.

TRIAL PERFORMANCE TEST RUN:

1. Trial test runs will be performed on municipal sludge using the City’s existing dewatering equipment (Belt Filter Press).

2. Selected vendors for the trial run will furnish all sample polymer(s) at the vendor’s expense. It will be the responsibility of the vendor to demonstrate that the polymer being proposed can perform as requested. Each vendor will be limited to two (2) products per dewatering method for trial purposes. The material shall be free of any foreign matter or compounds that may injure dried sludge for use as a soil conditioner, or seriously influence process operation of the Water Pollution Control Facilities.

3. The following conditions will be followed during the trial test runs of each product before awarding a contract:

a. The Wastewater Division Treatment Supervisor, or his designee, will schedule the polymer testing dates with each vendor.

b. The City will allow the vendor to operate (under direct supervision by the City) all existing dewatering equipment if the vendor so desires to ensure the most effective and efficient performance of their product.

c. Through-put of sludge processed during trial test runs must be consistent with the volume processed during normal operations by City Staff.

d. The vendor will be allowed up to two (2) working days to perform trial test runs for polymer proposed based on belt press performance.

e. Vendor shall provide Excel spreadsheet with formulas for all applicable parameter calculations at the end of each trial run with finalized, legible calculations turned into the City staff at the end of each day of the testing period. Spreadsheet shall also include cost per dry ton of all test run trials.

f. The Vendor shall provide verification of the efficiency of their product, in volumes similar to Zetag 7879. Validation of pounds of biosolids treated per pound of product is required.

g. City personnel will collect samples from each trial test run and analyze for percent solids concentration and percent recovery filtrate. City personnel will provide the percent solids concentration of the sludge holding tank.
