Exchange Canisters and Testing Procedures

• The primary purpose of the Metallic Exchange Canister is to remove the silver thiosulfate emissions to a level below the Local, State and EPA guidelines. At the point that the canister begins to pass silver above the allowable limit, the canister must be replaced.

• The canister is tested at the point of entry into the facilities waste water stream with pollution control test strips that detects @ 5 parts per million. If the Metallic Exchange Canister is passing silver @ 5ppm or above then a replacement canister will be installed.

• The disposal of the metallic exchange canister must be handled according to accepted EPA, State and Local guidelines. These canisters cannot be stored on site for a long period of time or discarded and therefore the expired canisters must be incinerated.
