The ProMinent Ultromat continuous flow dry polymer makedown system is the ideal choice for small to medium size polymer applications. The Ultromat features a variable-speed volumetric feeder, polymer wetting system, and three internal chambers each with individual mixers. Mixing energy is tapered through the chambers for optimal polymer makedown performance. The control system monitors the usage of the polymer in the final chamber and automatically makes more solution once it drops below the low level setpoint.

ProMinent Ultromat systems are available in a variety of sizes from 400 – 8000 L/h, and can be customized for different applications. The tanks of this 4000 L/h unit was constructed taller than the standard design to accommodate a smaller footprint. This also features a built-in vacuum for powder polymer transfer, eliminating the need to carry polymer bags to fill the hopper.

The 400 L/h Ultromat system pictured here includes a polymer transfer vacuum, and is paired with Blue-White M3 peristaltic tube pumps. The viscosity of polymer solution makes it an ideal pairing with peristaltic pumps, which have no internal check valves and do not get plugged up with polymer.

This is another 400 L/h Ultromat system, paired with progressive cavity pumps. Progressive cavity pumps also have excellent performance with viscous chemicals, though we typically reserve their use for larger systems (above 600 L/solution dosing). For lower capacities, the high turndown ratio offered by Blue-White or ProMinent electronic peristaltic pumps is beneficial for operational tuning.

For large applications, bulk bag delivery of dry polymer is most economical. This large 8000 L/h ProMinent Ultromat system includes a bulk bag frame with monorail hoist, and a vacuum transfer system to bring the dry polymer to the makedown unit itself. Progressive cavity pumps (not shown) deliver the prepared solution to a dewatering centrifuge.

ProMinent’s TOMAL PolyRex makedown system is a highly customizable batch polymer makedown system, available in capacities starting from 600 L/h, all the way to 23000 L/h or higher. This system features a bulk bag support frame with sealed glove box for bulk bag handling, volumetric feeder, wetting cone, eductor, and stacked mix and storage tanks.

The TOMAL PolyRex dual auger volumetric feeder provides a pulsation-free curtain-like discharge of polymer. This steady metering ensures polymer particles have the most exposed surface area for contact with the water in the wetting cone. This initially wetted polymer is sucked into the eductor at the bottom of the wetting cone and brought to the mix tank.

The wetting cone has a internal flushing water line that rinses the full perimeter of the wetting cone. This keeps cone free of polymer build up, which over time would lead to system plugging.

The dry polymer does not necessarily need to be right next to the polymer system. This TOMAL PolyRex system uses a vacuum (red component in photo) to bring dry polymer stored in another room into its feed hopper.

Another example of a system with vacuum transfer of polymer from an adjacent location into the PolyRex feed hopper.

The ProMinent ProMix is a compact and reliable means of activating neat polymer. The system consists of a ProMinent Dulcoflex peristaltic tube pump, primary dilution and mixing in a three-stage mixing chamber, and post-dilution with a static mixer.

Solution leaving the ProMix system is immediately ready for use – no additional storage or pumping is required. The system may be run on demand by the process requiring polymer. For batch-type applications, the prepared polymer may be stored in a tank and metered as required by the downstream process. The unit shown here discharges is in a batch application and the polymer is stored in the polyethylene tanks shown behind the system.
