Praestospeed™ 120 Modular Dissolving System

Mining and municipal operations consume large volumes of powder flocculants for water treatment and dewatering. Being able to dissolve granular polymer formulations efficiently is a high priority. The Praestospeed 120 modular dissolving system is the newest generation of fully automated equipment for dissolving granular flocculants.

This state-of-the-art system is faster and more effective than conventional equipment. While conventional facilities take at least 60 minutes to create 1,000 liters of polymer solution, the Praestospeed 120 system needs just 10 minutes to produce a 2-percent polymer solution that is ready for immediate dosing.

In addition to speed efficiencies, the Praestospeed 120 system provides benefits including:

  • Up to 90% reduction in the volume of required flocculant solution
  • Up to 92% reduction in the quantity of drinking or plant water
  • Up to 20% reduction in the required quantity of polymers
  • Up to 80% reduction in the amount of electricity required

How it Works

The Praestospeed 120 modular dissolving system uses an automatic batch process. The heart of the system is its dispersion unit, which processes the polymer in two phases. Operating on the rotor-stator principle, the unit uses controlled, high-speed turbulence to produce a perfect solution. This method is far superior to the shearing effect produced by conventional systems.

The Praestospeed 120 system can be programmed to produce a solution of any desired concentration between 1 and 2 percent, in increments of 0.1 percent. The system is easy to use and, thanks to a powerful onboard microprocessor, automates the entire production process. On and off functions can be linked to external supply levels, and a touch panel facilitates operator input.

Markets and Applications

Mining
The Praestospeed 120 modular dissolving system can help mines and mineral processors efficiently prepare flocculant solutions for tailings dewatering and thickening operations. The system accelerates polymer production while using less flocculant and makeup water, resulting in significant cost savings for mining and mineral processing operations.

Municipal
Large municipal water treatment facilities that use granular flocculant systems for sludge dewatering and water clarification can benefit from the Praestospeed 120 system’s advanced dissolving technology. It helps municipalities to reduce water and flocculant consumption.
