Abstract |
The report documents a pilot-plant study of the use of advanced waste treatment methods in upgrading metallurgical cokemaking wastewaters to Best Available Technology (BAT) levels. Mobile treatment units, operable at a flow rate of 19 1/min, were used. Two physical/chemical treatment trains were studied: (a) alkaline-chlorination/filtration/activated-carbon, and (b) alkaline-chlorination/sodium-bisulfite-dechlorination/filtration. For each treatment studied, samples (including toxic pollutants) and operational data were obtained for later use in assessing and comparing treatment adequacy. Chlorination was effective in consistently reducing pollutant concentrations to below BAT levels, except for total cyanide. Filtration was essential as an adjunct to alkaline chlorination for post-treatment suspended solids removal. Activated carbon and sodium bisulfite were efficient in removing excess chlorine resulting from treatment by alkaline chlorination, although carbon was more effective in removing organic priority pollutants. |
