Photographic And Imaging

Fixer solution dissolves undeveloped silver halide out of film and plates. After enough cycles it stops fixing and becomes waste, carrying 3 to 6 grams of silver per litre with it.

What matters here

Silver pulled out of spent fixer at 98 percent recovery, with residual below 20 mg/L.

The silver is complexed, not free

Sodium thiosulfate forms stable silver complexes in solution. They resist simple precipitation, which is why electrolytic reduction is the route that works.

80 grams from 20 litres

At an average of about 4 grams per litre, a recovery machine processing 20 litres of waste solution recovers roughly 80 grams of silver in one operation.

No reagent needed

The spent fixer is itself the electrolyte. No additional chemicals are added, unlike the displacement methods it replaces.

Discharge inside the limit

Recovery of 98 percent or better with residual silver in the treated liquid below 20 mg/L, which the source states complies with environmental emission standards.
