Twindos

The dry polymer dissolver unit for retention - batch system

The Twindos is an automatic powder polymer dissolver unit for the production of a highly effective polymer solution, which is used in retention as well as in other applications.

An alternating operation of the two maturation or dosing chambers ensures a flocculant maturation time of 60 minutes.

The flocculant is injected into the batch chamber through the dry product dosing device.
The wetting device provides for a homogeneous wetting of the product.
The wetted product is then fed into the draught tubes of the Verdos agitator system. Upon reaching an optimum mixing ratio, the product overflows into the maturation chamber, where it is gently homogenised and provided as the matured product.
The resulting polymer solution can now be injected into the process as a ready-to-use solution through the dosing pumps without intermediate tanks.
An alternating operation of the two maturation or dosing chambers ensures a maturation time of 60 minutes.
The system can be used either with dry or liquid media.

The system is controlled via a Siemens Simatic PLC. The touch panel can be used to enter all parameters required for optimum system operation and to monitor all process data, ensuring the preparation of a consistent polymer solution.
