Laboratory treatment of the sample involving Dissolved Air Flotation (DAF) pretreatment and in line ozonation was performed on a sample of recirculating cooling tower water that was obtained from Transo Envelope Company of Jersey City, NJ. Various parameters including turbidity, color, pH, total hardness, TOC, and bacteria levels as well as specific concentrations of constituents such as iron and copper were monitored. After each stage of experimentation various parameters were measured to determine optimum treatment for the specific water. Ozonation in combination with DAF pretreatment produced optimum water quality with the DAF pretreatment being responsible for most of the water quality improvement. Ozonation was found to be necessary for bacteria removal. Operating cost estimates are included and compared to those of a conventional system of chemical treatment.
