Polyelectrolyte dissolution systems

Sodi Scientifica has been operating for many years on the market with its line of automatic powder dissolution systems having high level of quality and performance indexes. AUTOMIX systems, besides having a highly professional operation, fully controlled by microprocessors, allow for considerable savings in economic terms, as regards the consumption of polymer and for the operational costs and maintenance.
AUTOMIX is a packaged plant consisting of two main sections:

  1. Polymer metering unit;
  2. Dissolving, aging and dosing tank;

The first section is made up of a stainless steel hopper which contains the powdered polyelectrolyte and is provided with antibridge vibrator, powder’s minimum level probe, timer-operated constant-flowrate screwfeeder, pressure switch – solenoid valve – water intake flowmeter, instantaneous powder-scattering water jet-disperser and a computerized control box housing all the electric and electronic devices for a fully automated operation of the system.
The second part, instead, consists of a stainless steel tank with a nominal capacity of 1000 – 2000 -3500 or 5000 liters of solution, divided into two or three sectors by bulkheads. Each sector is equipped with low-speed stirrer, level probes and lumps-retaining end filter.

Automatic Operation

In this version Automix provides a synthesis of accuracy of metering, ease of use and automation. The ease of use is one of the distinctive features of this system, without sacrificing the main features, typical of more sophisticated equipment. Sturdiness and reliability complete the profile of this plant. Accuracy in metering is achieved by keeping the intake flow rate steady so that, by knowing the screwfeeder capacity, a constant water/powder ratio can be obtained as well.

The concentration of the solution is set using the knob in front of the electrical panel. Contrary to Automix Max 40/c, this version requires a separate control panel for the dosing units and is not provided with an end-filter.

Accessori a richiesta

A number of accessories are available on demand, such as, just to name a few:
Screwfeeder heater: resistance for heat power of 210 W – 24V voltage, provided with thermal switch set at a fixed temperature. It prevents the polyeletrolyte to become packed in damp and cold environments.
Static Mixer: PVC mixer for spirally feeding the solution of the two metering pumps into one water flow and ensuring a uniform distribution thereof.
Automatic powder loader: fully operated through the electronic panel of Automix, thanks to the loading system equipped with steel lance for the drilling of the bag, has made it possible to solve the problem linked to the danger of possible dusting of the product.
Pumps support: stainless steel AISI 304 support for housing the metering pumps.
230 dm3 Hopper
Outlet and discharge piping
