Automatic Polyelectrolyte Preparator

Automatic Polymer Dosing

Preparation systems to dissolve and dilute powder and emulsion needed at the conditioning and mechanical dehydration of the sludge to be treated inside the purification plants, SEFT proposes an automatic station is polyelectrolyte polypreparing machine for the  continuous preparation of the flocculant substances necessary to complete the chemical / physical process that favors the dewatering of the sludge.


– Operation:

– The powdered polyelectrolyte stored in a hopper is transported by a screw conveyor, and dosed in a first sector of the dilution tank, where it is appropriately diluted with water thanks to the action of an electromechanical agitator which favors its dissolution. At the end of this first phase the solution passes into a second sector to complete the preparation, to then conclude the process in a third sector of maturation, and be ready for use.


– Same process for the preparation of the polyelectrolyte from a liquid concentrate takes place, instead of the powder doser a dosing pump is installed. Combined system liquid / powder systems allow maximum flexibility of use, also on the same equipment


-The passage between the various internal sectors of the tank is managed and controlled by a system of communicating vessels that automatically interrupt or resume its function once the desired level is reached by sector, this process is controlled and automated by an automated PLC electrical control panel.


The system is composed of:

• Hopper with hinged lid and safety guard in AISI304 L or AISI316 L, with capacities from 40 o 70 liters depending on model • Dosing screw operated by motovariator equipped with indicator of speed for the control of the scope

• A group of control and adjustment water supply from 200 to 3000 Lt / h (min 2 bar) consists of a water filter, a pressure reducer with pressure gauge, a pressure switch, a flow regulator valve, a solenoid valve and a flow meter, all installed on the tank and connected to the general framework

• A control probe levels

• A main control panel mounted on the machine
