Clarification of recycled water of gas cleaning of a blast furnace using a water-dispersible flocculant

Summary

The results of laboratory testing of choosing the optimal flocculant for clarification of recycled water of blast furnace gas cleaning are presented. Laboratory testing was carried out according to the standard method of sedimentation (clarification) in glasses. It has been shown that the use of ATE 12520 liquid water-dispersible flocculant provides for the successful removal of suspended solids and turbidity from gas cleaning recycled water. The proposed chemical treatment program was recommended for commercial testing of the clarification system of gas cleaning recycled water of a blast furnace at one of the ironworks in Russia. The ATE 12520 flocculant dosage range recommended for testing (as commercial chemical) in terms of wastewater supplied to the circular sedimentation tank is 0.3–0.5 g/m³.
