Solution and dosing systems CONTINUFLOC with conveyor AIRLIFT for powdery polyelectrolyte, dosing station for polymer solution with piston diaphragm dosing pumps FKM.
A particular challenge in this project was that the equipment had to be installed and taken into operation at normal operation of the power station, within a very short time.
For the design and installation the restrictive site conditions had to be considered.
Cooling water treatment in a power station
Should surface water be processed to generate cooling water of a power station, it must first be cleaned from impurities. Otherwise these may have negative effects on the pipes, valves and heat exchangers. In a multi-step treatment process this is done through flocculation. In the described project powdery polyelectrolyte was used as flocculation agent.
Preparation of powdery polymer to a polymer solution
The polyelectrolyte from bags is emptied into a floor hopper and lifted by an AIRLIFT loading system into the dry material feeder of the two-chamber pendulum systems CONTINUFLOC.
CONTINUFLOC systems are fully automatic systems for the preparation of granular and concentrated liquid polyelectrolyte. The systems are supplied completely with switch cabinet, wiring and piping and are electrically and hydraulically tested in our factory.
The CONTINUFLOC stand out due to an optimal powder wetting system and provide sufficient maturation time regardless of polymer type or concentration.
Dosing of matured polymer solution
To make from surface water via flocculation cooling water, the matured polymer solution is metered via a dosing station for viscous products. The dosing stations were delivered on skids and completely pre-assembled and tested. For dosing the robust and proven piston diaphragm dosing pumps type FKMV are used, which are specially designed for high viscosity products. The pumps are adjustable 0-100% and have a built-in safety valve.
