The European ZERO BRINE project starts in January 2019 with a pilot plant on the industrial demo location ‘Plant One’ in Rotterdam in the Netherlands. The objective is reducing industrial saline wastewater by recovering minerals and clean water for reuse. The ZERO BRINE-project, financed by Horizon 2020 started in 2017.

Twenty-two partners from ten different countries are investigating how to reduce industrial waste water. Henri Spanjers from the Delft University of Technology is coordinating the project in Rotterdam. “Industrial flows of saline waste water are growing due to the widespread application of cheaper membranes and the growing importance of water reuse. It also means a sustainable solution for brine is needed.”
The demonstration project is realising pilot installations for diverse industries in Spain, Turkey, Poland and The Netherlands. Two pilots are located in the Botlek area of Rotterdam Port. According to Spanjers the project partners worked hard on the preparations of the Dutch pilot plants. Several parts of the pilot installations are already tested in the lab, and Plant One has been selected as a pilot location. This industrial pilot plant supports start-ups specialised in sustainable process technology.
The pilot installation consists of a nano-filtration unit, a crystallization unit and an evaporator. Lenntech Water Treatment is producing the nanofiltration unit, the university of Athens is providing the evaporator and the university of Palermo will provide the crystallization reactor.
The pilot installation will treat a cubic meter of regenerated water per hour. The saline water flow comes from the demi water plant of water company Evides who provides demi water for a number of petrochemical companies in the industrial region Botlek area of Rotterdam Port.
