- Model ULDa - Metering Systems

From

Extraction rates of up to 2,000 l/h. The ProMinent metering system Ultromat ULDa is an automatic polyelectrolyte preparation system. It is useful wherever polymers need to be automatically prepared as polymer solutions to act as flocculation aids.

A good solution when preparing polymer solutions as flocculation aids.

Ultromat ULDa double-decker systems are used to process liquid and powdered polymers. The system consists of two separate PP storage tanks, stacked above each other, preventing product carry-over. The polymer solution is batched in the upper storage tank and can be transferred to the lower storage tank once the maturing time has elapsed.

  • Processing of liquid polymer (0.05-1.0%) and powdered polymer (0.05-0.5%).
  • No mixing of fresh and matured polymer.
  • Wide range of versions for specific applications.
  • Operator-controlled input of the solvent concentration and calibration of powder metering unit and liquid concentrate pump.
  • Water fitting with flow meter and fitting set for the dilution water.
  • Gentle mixing of the polymer solution (electric stirrer).
