Water reuse in the petrochemical industry
Freshwater resources are increasingly under stress conditions and there exists a huge mismatch between available water resources and rising water demand in many parts of the world. In Europe, water scarcity affects at least 11% of the population and 17% of the territory. Regions with low rainfall and high population densities are prone to water stress same as areas with intense agricultural, industrial or tourism activities. Therefore, protection of water resources is one of the main milestones of environmental protection in Europe.
The industrial sector is the second largest consumer of water after agriculture, using 22% of the freshwater volume drawn in the world. Within the industrial sector, the petrochemical industry is a major water user, mainly for cooling and steam production, and generates considerable volumes of wastewater. At European level, this sector alone is responsible for 1,750 million cubic metres of wastewater a year. To face this challenge, the REWATCH project aims to validate the economic, environmental and technical feasibility of an innovative treatment system for water reuse in the petrochemical industry.
The main stages of REWATCH innovative treatment for water reuse
1 Wastewater generation
2 Physicochemical pre-treatment
3 Biological process
5 Reverse Osmosis
6 Water deionization
7 Use of reclaimed water
From 22 to 26 June 2020, LIFE REWATCH project was present on the Innovative Water Week, organized by Water Europe. LIFE REWATCH had a virtual booth, where information of the project was showed (https://wie-2020.b2match.io/page-2591). Carlos Ramos, researcher from...
On June 16th the LIFE REWATCH project team hosted a virtual open day. The virtual seminar gathered three partners of the LIFE REWATCH project: Miquel Rovira (from Eurecat, coordinator of the project), Elisenda Taberna (from VWS, technology supplier of AnoxKaldnesTM...
Currently, LIFE REWATCH project is running the prototype with the whole treatment train, including the following technologies: AnoxKaldnesTM moving bed biofilm reactor (MBBR), which is devoted to decrease the organic matter content of the petrochemical wastewater. Two...
