Specifications include, but are not limited to: 3.1.1 Cationic, Anionic Emulsion Polymer and Dry Polymer for sludge dewatering and settling delivered various Water Treatment Facilities.; 3.1.1.1 Vendor shall have a minimum ten (10) years of experience using polymers in geotextile dewatering applications in order to have the knowledge of the appropriate blend of polymers to treat the AMD water at the facilities. Proof of experience should be submitted with bid but must be submitted prior to award.; 3.1.1.2 Vendor must be able to store or warehouse a minimum of 11,000 pounds of polymer in the State of West Virginia at all times.; 3.1.1.3 Vendor shall be the manufacturer of the specific product being offered or the manufacturer’s sole authorized representative for this Bid. Manufacture is defined as conducting the actual polymerization of monomers into the specific polymer being offered.; 3.1.1.4 Emulsion Polymers shall have a minimum shelf life of six (6) months when stored between 40 degrees and 95 degrees Fahrenheit.; 3.1.1.5 Emulsion Polymers must come packaged in 55-gallon drums, 275- gallon totes and bulk for storage and dispensing at the treatment facility. ; 3.1.1.6 Dry Polymers must come packaged in 50-pound bags or 5-gallon pails for storage and dispensing at the treatment facility.; 3.1.1.7 Polymer feed rates must not exceed the acute toxicity to fish per the product’s SDS. Vendor must supply SDS with each delivery.; 3.1.1.8 A Prebid meeting will be held at the Omega Mine facility (refer to Item 3 of “Instructions to Vendors Submitting Bids”). At the Prebid meeting the vendors will collect water samples to conduct their jar testing with their polymer mix.; 3.1.1.8.1 Jar testing results shall be submitted with the vendors bid. See Instructions to Vendors Items; 3.1.1.8 through 3.1.1.10, for details.; 3.1.1.9 Prior to submission of bids, vendors shall perform jar testing from the water at the Omega Mining site, at their own non-reimbursable expense, to determine the number of milligrams per liter of polymer needed for settling and dewatering AMD and the price per pound.; 3.1.1.10 The dewatering and settling applications results will be based on the filtrate shall be less than 3.0 mg/L Total Iron and 0.43 mg/L Total Aluminum. The dewatering polymer shall treat sludge pumped to the geotextile dewatering containers at a maximum rate of 170 gpm.
