77-14: Hexavalent Chromium Reduction in Cooling Tower Blowdown-Evaluation ofThe heavy metals content of wastewaters is being regulated in many areas of the world. In particular, the concentration of chromium which can be discharged in effluents is being severely restricted. The EPA has imposed a 0. 25 mg 1 total chromium limit on gas plant effluents in Texas.
