Technical Description
In the preparation chamber the stock solution is prepared. In relation to the water flow polyelectrolyte is dosed via the powder polymer feeder o the liquid polymer dosing pump into the jet nozzle device. In the device the polymer is wetted with the required amount of dilution water. The dosing time required by the dry material feeder is calculated by the PLC according to the calibrated dosing capacity and the adjusted concentration. The solution is transformed into a ready-for-use-solution in the preparation and the ripening by slowly operating agitators. To avoid mixing of fresh prepared and ripened polyelectrolyte solution the agitator in the ripening chamber is not in operation during preparation. While the preparing system is in operation the ripened polyelectrolyte solution flows into the dosing chamber. The ripened stock solution is taken out of the dosing chamber continuously. The preparation takes place discontinuously according the level in the dosing chamber. The preparation is started by reaching low level and stopped by reaching high level in the dosing chamber. This design provides continuously the required stock solution in compliance with the ripening time.
The power distribution and the process control of the plant is installed in a control panel mounted onto the preparation plant. The control panel consists of all required parts and is equipped with a PLC which controls the process. On the EPROM the process program is stored including the possibility to start an addition liquid polymer dosing pump.

VA - Polyprep 2KB
VA - Polyprep can be operated using either powder or liquid polymer. Slowly running agitators made of stainless steel prepare a ready-to-use solution in the preparation and ripening chambers which is then discharged into the dosing chamber. From there, the solution can be withdrawn continuously. The whole process runs automatically and is controlled via a userfriendly Touch Panel on the switch cabinet.
