  • This study analyzes economic feasibility by looking at the case of wastewater reclamation and reuse system of Osan, the only place currently operated in Korea, exploiting wastewater uniquely reused as industrial water. Furthermore, this paper examines the problem in wastewater recycling and present the method to expand the potential of using reclaimed water. Method to activate the reuse of wastewater as industrial water. First, it is required to provide self-governing body and demander with diverse information on this project so that they correctly recognize the reuse of wastewater as industrial water. Second, law should be amended so that the water quality requirement of reused water can be given in the national level to supply industrial water depending on right standard. Third, financial support should be expanded in diverse parts so that more private investment advantageous to investor can be made, for instance, BTL, BTO.

  • The predictive capacity of wastewater treatment facility in the industrial park was estimated by the traditional method and on-the-spot survey such as certification of wastewater report and the invoices of water supply and ground water supply. The ratios of a converted wastewater to supplied industrial water between traditional method and on-the-spot survey in the estimation methods were different. By using traditional method, the business type of clothes, accessary and fur production had 77.18 % of waste ratio of wastewater and $10.72m^3/day{\cdot}1000m^2$ unit mass of wastewater as the highest among 9 business types. With the respect to the on-the-spot survey, food manufacturing business type had 75 % of waste ratio of wastewater and $8.35m^3/day{\cdot}1000m^2$ unit mass of wastewater as the highest values. The amount of wastewater from on-the-spot survey method was 541 $m^3/day$ less than one from traditional method.

  • Reuse of wastewater will intensify in the coming decades due to water shortage, the change of climatic conditions, the need for industrial and agricultural use and the necessity of improving health and environmental conditions for the growing population. This paper considers (a) the status and trends of wastewater reuse and reclamation in the world, (b) case studies of wastewater reuse projects, (c) analysis of technology level, (d) forecast of global market, and (e) the future views and directions in development of wastewater reuse technologies. Based on the available documented literature, this paper provides a review assessment of the current status of the wastewater treatment processes including potential applications for reuse. Key challenges for both wastewater treatment and reuse are also discussed in the paper and include recommendations, e.g. cost, effluent water quality, energy use and technical solutions, for future developments.
