Analysis and design of a pilot system for the treatment of industrial wastewaters using membrane processes

Abstract

The purpose of this study is to undertake the characterisation of industrial-type wastewaters and to provide the design and application of a treatment system using membrane technology backed up by multiple laboratory-based experimental trials to observe and determine the stages required in the process. An analysis of the various industrial sectors of the Autonomous Community of the Canary Islands, Spain, enabled us to establish the source and characteristics of their wastewaters along with the quality indices and typical mean concentrations. The theoretical models were adapted to the observed effects of the trials in the pilot system with an assessment of the various operational possibilities that included operating ranges meeting ASTM standards. These standards included the case of industries that require the use of high-quality water.
