LIFE+ REWATCH: Demonstration of an innovative recycling scheme to increase the water efficiency in the petrochemical industry
The LIFE REWATCH project (LIFE15 ENV/ES/000480) aims to validate the economic, environmental and technical feasibility of an innovative treatment system for water reuse in the petrochemical industry.
What? Decrease the environmental impact of the petrochemical industry
How? Implementation of an on-site innovative wastewater recycling scheme to increase water efficiency in a petrochemical industry
Where? Petrochemical complex of DOW Chemical Ibérica in Tarragona, Catalonia, Spain.
Who? DOW Chemical Ibérica, Veolia Water Technologies, Fundació CTM Centre Tecnològic, KWR Water, and the European Water Supply and Sanitation Technology Platform, WssTP
When? September 2016 – December 2019
Why? Decrease freshwater consumption by the petrochemical/industrial sector
REWATCH proposes an on-site reuse scheme including five different technologies to constitute a completely new treatment scheme in the petrochemical industry: physicochemical pretreatment, moving bed biofilm reactor (MBBR), ultrafiltration (UF), reverse osmosis (RO) and water deionization using ion exchange resins (IER). This treatment scheme is highly versatile because it is designed in such a way that the wastewater may enter at any point of the treatment train depending on its initial composition and reclaimed water may also exit after each treatment step depending on the obtained water quality.
