The treatment of water and wastewater may involve numerous chemical and physical unit processes. Each unit process is selected on the basis of its ability to accomplish specified treatment objectives. Ozone treatment is one such chemical unit process alternative. Ozonation is commonly practices abroad. Presently, nearly one thousand water treatment facilities in Western Europe use ozone for various applications. Ozone treatment of water is not common in the United States with just five installations as 1979. However, rising costs of chemicals, recent advances in ozone technology, and new treatment regulations and discharge requirements have enhanced the use of ozone as a water and wastewater treatment alternative. The theory of the reactions of ozone for treatment of water and wastewater is well recorded. However, due to the site-specific nature of the ozonation process, it is difficult to predict he practical or economic feasibility of ozone treatment without supporting data. These data may be best obtained by conducting ozonation experiments at the prospective site on a pilot-plant scale. The objectives of this research were: (1) To design, specify, and direct the construction of a portable ozonation pilot plant suitable for water and wastewater treat feasibility studies. (2) To evaluate the performance of the ozonation pilot plant under field conditions. The contents of this paper include a review of the factors related to the design and construction of a pilot plant ozonation system. The components of the pilot plant are also described. Finally, the results of a performance evaluation of the pilot plant are discussed.
