The document provides detailed requirements for a polymer preparation system, specifically focusing on the importance of a high shear mixing environment. It emphasizes the need to choose suppliers who employ this technique. The system should be capable of preparing dry, solution, and emulsion polymers, with separate entry points for each type. The wetting chamber should have an acceleration zone and a second stage mixer with a high shear mixing impeller. The mixing tank should be made of flame retardant material and have a minimum capacity of 150 gallons. The process cycle should be initiated by low level in the mix tank and shut down by high level. Water flow should be maintained at a constant rate. The system should have a total electrical service of 240 VAC - 60 Hz single phase - 30 amps. Additionally, the document mentions the inclusion of a disperser package and the reliance on gravity for transferring dry polymer from the feed device to the wetting chamber.
