Waste water containing heavy metals can be problematic with increasingly stringent discharge limits. Traditional hydroxide precipitations may not be able to meet the low limits due to agents (chelants) that inhibit precipitation. In these situations, carbamates or other sulfide compounds are utilized. The downside of some of these compounds is that they can cause effluents to fail WET tests. Carbamates are also used as biocides so other options need to be considered.
Fife FC-8880 is an environmentally benign solution that will not cause failure of wet tests and is effective in both acidic and alkaline pH environments. Additionally, the heavy metals are so tightly bound that they can pass landfill TCLP tests. The thermal stability of FC-8880 allows it to be sprayed into hot flue gas streams in order to remove mercury, arsenic, selenium in coal combustion plants.
Examples of applications are listed below
- Removal of mercury, cadmium, selenium and other heavy metals in flue gas.
- Removal of mercury, cadmium, selenium and other heavy metals in flue gas scrubber water.
- Plating operations.
- Electronic circuit etching processes.
- Mining tailing treatment ponds.
- Steel production and metal precipitation of waste water.
