DESCRIPTION AND WORKING PRINCIPLES

The polyelectrolyte preparation and dosing station is devised especially for the production of base solutions or solutions using synthetic flocculants (polyelectrolytes). These solutions can be used in all cases where colloidal substances need to be separated from waste water. The user inserts the data regarding the concentration of the solution, the hydraulic calibration of the powder metering device and the liquid concenetrate pump, according to the work requirements at the time.

MANUFACTURING FEATURES

The automatic mixing plants with two or three chambers for flocculant substances in powder form for producing a dosing solution of 0.05 and 0.5% consist of:

• Combined container in stainless steel for preparing, maturing and storing polyelectrolyte, with reinforcements and brackets for the other aggregates;
• Bottom and overflow discharges in stainless steel (min 70 lt.)
• Metering device for dry substances, of variable capacity, and loading hopper with hinged cover and seal, propeller with three-phase motor and variable speed;
• 2 or 3 low-speed electric agitators in AISI 304 stainless steel with motor;
• Pipes for metering the concentrated liquid;
• Washing system for washing and dampening the powder, with a washing device, nozzle, flow measuring device and a set of fittings for the water solution.
