The evaporation process is controlled by a pLc that automatically controls the feed supply of the concentrate as well as the discharge of the distillate and the concentrate, thus requiring only minimal supervision by the worker.

IN is used to filter the neutralised solutions and retain the copper, zinc etc hydroxides.

This microfiltration unit is designed for the treatment of wastewater coming from the jewelry production.

The water contains normally a certain quantity of solid small particles of precious metal in form of fine sludge, difficult to treat with standard equipment as gravity sedimentation tanks, paper/polypropylene filter presses.

The demineralization process is needed in order eliminate water salinity. It is achieved by means of exchange resins, (“strong” Cationic and “strong” Anionic), which can be regenerated from hydrochloric acid and sodium hydroxide (4-8% HCl + 4-8% NaOH).
The resins are contained in 2 special cylinders with polyethylene inner shell.

The water is supplied by means of the pressure existing in the water network, alternatively the system can be equipped with an optional pump and storage and settling tanks.
