Abstract

This paper proposes a multi-criteria approach to assess current technology systems in water treatment (WT) plants and water waste treatment (WWT) plants to find out the main implications on the quality of service. Presently, the plant production process and efficiency improvement of WWT plants has become a challenge for WWT plants. The need of cost-efficient and reliable treatment processes has significantly increased so as to meet the level of environmental regulations and national goals. A case study has been carry out in a main WWT company in Chile with the purpose to identify priority plants that must improve its technological standard. We have considered five technological systems that are indispensable in the process. With empirical data, expert opinions and combining scoring method with the Analytic Hierarchy Process (AHP) it was possible to obtain a plant ranking for the problem in study.
