| Abstract | Tertiary treatment of wastewater with ozone in a nominal 50,000 gal./day pilot plant at Blue Plains, Washington, D.C., is described. Plant performance for each feed is described in terms of COD reduction characteristics and the effects of pH, ozone concentration, feed pretreatment and initial COD on reaction rate. Data are given for ozone solubility and half-life in pure water and various wastewaters. Bacteria kills are reported. Estimates of capital and operating costs are presented for large plants to treat wastewater with ozone and a procedure is given for optimization of costs for large plants. (Author Modified Abstract) |
