Automatic polyelectrolyte preparation systems

Features
PL
Plant for manual preparation of polyelectrolyte
Systems for preparation of solutions from powder
PLE
Systems for preparation of solutions from emulsion
Polyelectrolyte solution is not very stable and its efficiency decreases with time.
So the solution must be prepared only when necessary in order to use the whole
quantity prepared and avoid wastes.

• Preparation tank with covers, divided
into three sectors for dissolving,
maturing and storage
• Control and electrical command
switchboard including the
automatisms and indicators for fully
automatic plant operation
• Solution dosing system, generally
consisting of dosing pumps selected
from the numerous versions available
from our range (ask for the specific
catalogue)
The preparation tank is divided into three sectors: dissolving V1, maturing V2 and storage V3,
interconnected by siphons that form a preferential path necessary for the formation of a top
quality solution. The powder from the dosing unit is mixed with water, which, appropriately
sprayed, from a nozzle, carries out the important action of dispersion.
• Automatic functioning
• Separate dasage of water
and powder
The water/powder mixture then drops into the tank below where the dissolving phase begins.
In dissolving sector V1 a slow agitator keeps the contents of the tank in movement, thus
favoring homogenization of the solution.
• Stainless steel construction
• Compact size
• Ready to be anchored to the
floor if required
• No foundations necessary
The siphon transfers the solution to the maturing sector V2 where another slow agitator keeps
it homogeneous until maturing is complete. Then the solution is transferred to storage sector
V3 from which it can be transferred for use.
The level switches installed in this sector control the
systems automatic functions:
High and normal level switch: when the solution
reaches the high level this switch stops the powder
dosing unit and closes the water inlet solenoid valve. In
the normal level position it enables dosing unit
functioning and opens the water solenoid valve.
Low level switch: when the solution falls to minimum
level this switch stops the dosing pump and lights up an
alarm indicator on the electrical switchboard.
Options
n Heating of dosing unit discharge pipe
n Automatic dosing pump adjustment
n Water pressure reducer
n PLC programmable electrical switchboard
n Overflow and drain header
n Third agitator in the storage section
n Powder minimum level switch
n Pneumatic powder loading
