Waste water concentration processes. State of the Art

Summary

This report presents the state of the art in processes for concentrating aqueous industrial effluents. The processes studied are thermal evapoconcentration processes, membrane processes, mechanical processes and physico-chemical processes. For each of these processes, the work carried out provides information that is : - technical: physical phenomena involved, principle of the process, - practical: fields of application, advantages, performance, limits and disadvantages, - economic: data on energy consumption, economic data (costs of installations, consumables, maintenance operations). Specific case studies are detailed: leachates from storage centres, mechanical engineering and surface treatment effluents, and methanisation digestates. This document also provides a reminder of the regulations governing effluents and current effluent discharge standards, as well as the conditions for admitting liquid waste to treatment centres. This report helps to identify a dedicated strategy (resulting from a combination or otherwise of different processes), in order to provide an optimum technical and economic solution for a given facility.

Keywords: effluents liquides, procédés, concentration, évapoconcentration, membranes, lixiviats, effluents de la mécanique, effluents de traitement de surface, digestats de méthanisation, waste water, processes, concentration, evapoconcentration, membranes, landfill leachate, effluents waste water from mechanic industries and surface treatment industries, estate from anaerobic digestion
