The FlowMix® is a single-stage, continuously
operating polymer dissolution unit for liquid polymer. The core
of the unit is a Mixing Pump that dynamically supplies the required
mixing energy to the solution during the pumping process.
The Mixing Pump meters dilution water and polymer
in the inlet chamber of the pump via two separate suction sides.
The required mixing energy is applied exactly at the point where
water comes into contact with polymer. Next, polymer forms abruptly
a three-dimensional net-structure of a large surface. On the pressure
side the solution is ready for use and of high viscosity. Ageing
time for polymer (ageing time = time required for the formation
of the three-dimensional net structure) is not necessary. Lump formation
as a result of introducing both products without sufficient mixing
energy - as often noticed in the case of conventional units - can
be successfully avoided due to the application of the FlowMix®.
Increase of effectiveness
The applied polymer is therefore economically and
effectively brought into the solution. As a result, the polymer
consumption decreases, whereas the effectiveness of the solution
Dilution water is supplied to the Mixing Pump from
a water container through a float valve. This water container, which
is mounted at the FlowMix®, guarantees constant pressure and
an atmospheric disconnection of the unit from the water distribution
system. This, in turn, complies with the water balance requirements
for water-polluting materials.
No pump littering
The total amount of the solution as well as the
flow rate of the polymer commodity are both measured on the FlowMix®.
With the help of an integrated controller, it is possible to pre-establish
the required concentration of the solution, which remains constant
independently of the used solution amount and of the viscosity of
the product. Pump littering can thus be avoided.
FlowMix® capacity can be varied on the Mixing
Pump through a special control lever or an electrical positioning
drive at constant rounds per minute. In the course of this, the
suction volume of the Mixing Pump changes.
The concept of the FlowMix® enables an inline
application of the solution to the separation process. Tanks, metering
pumps, and after-dilution units are not required anymore. If the
FlowMix® is combined with this process, the solution will be
automatically adjusted properly in case of some process alterations.
