Silver Recovery Units Druckbutton anzeigen?

UTEC has more than 40 years experience in the production of industrial silver recovery units which work on the electrolytic current principle. There is a wide range of units for the use in recycling companies, film laboratories, photo-finishment, print- and x-ray environments.

Depending on the way the unit is used, there are electrical control units available for manual operation or for fully automatic current regulation; the latter unit measures the silver content by means of a calomel system.

Modified versions on demand!

We are supplier of KODAK Europe, Near and Middle East

UTEC silver recovery plants series PST have the following advantages:

- Low volumes and high electrolytic power.

- Increased efficiency and high agitation with roational cathode.

- Large cathode surfaces, enabling high current density without danger.

- Long service life - rigid PP tank, special acid resistant stainless steel for the rotational cathode and gear carrier and special carbon plates as anodes.

- The silver is easily „harvested“ from the removable cathode drum

- The silver recovered has a high grade of chemical purity, thus realize higher profits while reselling the silver.

- Small floor stand.

- No production of gas according to the safety examinations of the TÜV Bayern/Sachsen.

- This series is especially suitable for silver recovery of fixers in circulation with a development unit.

- Operation is also possible to recycle fixers stage by stage in circulation system with a store tank.


Principle of operation

Special anodes, made of an impregnant mixture of carbon and graphite are installed at the inside walls of a square plastic tank. Good agitation and a constant pure silver deposition is enabled by a fast rotating cathode drum. When a DC Voltage of up to 4 volts is passed through, silver is deposited in a layer of up to 15 mm thickness. When the silver has then been „harvested“, the plant is ready for operation again.

 

 

Automatic current regulation

Infinitely variable control of the electrolytic current in dependence of the silver content (with selector switch manual operation is also possible)

High silver content = high current
Low silver content = low current

 

The current is calculated and controlled permanently by a microprocessor unit. It is possible to preset 9 different programs or power steps.

 

By this means a low rest silver concentration is possible, without the formation of sulfide and precipitation. The silver is indirectly determined via an electrolytic balance which excludes contamination and destruction of the silver-sensitive electrodes and guarantees a durability for years.

UTEC has more than 40 years experience in the production of industrial silver recovery units which work on the electrolytic current principle.

There is a wide range of units for the use in recycling and waste disposal-companies,

print- and X-ray environment, photofinishment, professional film labs.

Depending on the way the unit is used, there are electrical control units available for manual operation or for fully automatic current regulation, the silver content is measured by our patented measurement system based on the calomel system.

Modified versions on demand !

Automatic filling, desilvering, adding of chemicals, filtration, emptying with dry run protection on demand.

UTEC silver recovery plants have the following advantages:

Increased efficiency by optimal flow (cascade and agitation)

Large cathode surfaces, 12 sqm !!! enabling high current deensity without danger.

Long service life rigid PP or PE tanks, special acid resistant stainless steel for cathodes.

The silver is easily “harvested” from corrugated flexible cathodes.

The silver recovered has a high grade of chemical purity, thus realize higher profits while reselling the silver.

No production of gas according to the safety examinations of the TÜV Bayern/Sachsen.
