Polymer Dilution Blend and Feed Specifications For General Use

Electronic Diaphragm Metering Pump

1.0 GENERAL

The contractor shall furnish and install polymer dilution blending and feeding units together

with all drives, motors, valves, piping, supports, controls, and accessories necessary for a

complete and operable system in accordance with the requirements of the contract

documents. Each system shall be completely piped, wired and tested before shipment.

2.0 PRODUCTS

2.01 General

The polymer dilution blending and feeding units shall be integrated equipment

packages to automatically meter, dilute, activate, and feed (emulsion, solution or

dispersion) polymers. Concentrated polymer and water shall be blended. The

process shall begin with a motor driven, high energy, injection head which shall

spread the polymer into thin layers for introduction to the water without the formation

of fisheyes or gels. The injection head shall have a multiple vaned, close tolerance

rotor. All of the dilution water shall go through the high energy zone for machines with

capacities of 1200 gpm or less. Units handling water flows in excess of 1200 gpm

shall utilize secondary dilution. Machines which feature secondary dilution shall

cause flow in excess of 1200 gpm to be diverted to the secondary dilution stage.

When flows reduce, the secondary dilution stage shall be shut down for flow rates

below 1200 gpm to allow all of the dilution water to, again, pass through the high

energy injection head.

After the initial high energy mixing, the solution shall be introduced into a low energy

static mixer. Static mixer shall contain a series of 316SS mixing elements housed in

clear PVC housing for viewing the final mixed solution. Static mixing elements shall

produce a high degree of back mixing. Systems that do not have a motor-driven

polymer mixing chamber shall not be considered equal. System shall be designed for

wash down duty. System shall have an electronic diaphragm polymer feed pump.
