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.
