Interreg Vlaanderen-Nederland

The IMPROVED project is funded by the INTERREG V "Vlaanderen-Nederland" programme, a cross-border cooperation programme with the financial support of the European Regional Development Fund. IMPROVED will build 3 state-of-the-art mobile research facilities that serve to purify the water in the most efficient way, estimate detrimental effects on the distribution system and test the impact of the water quality on the downstream process equipment. The project will last 3 years, starting at 1/01/2016.

Description of the project

The Zeeland Delta is a region coping with intense industrial activity and a scarcity of fresh water supplies. This forces companies in its borders to look for innovative solutions to optimise their water balance, like "reuse" of wastewater, short-circuiting the water cycle. Putting this into practice however is a slow process, due to many uncertainties that are involved with the introduction of new practices in existing process schemes. There is the crucial aspect that one needs to determine the process water quality needed for closing this water cycle without compromising the stability of the process, but also without overshooting its quality so costs and energy are efficiently spent.
Modules will contain a diversity of technologies in a plug & play mode. This means that mobile unites will be equipped with different and interchangeable units, depending on the needs. Therefore, the set-up is suited for the location and can simulate the process water chain of interest. Tests and measurements will be comprised of both on- and off-line measurements to determine the physico-chemical treatment technologies, distribution impact and process performance of typical chemical downstream equipment like boilers, cooling towers, cracking systems.
The installation will be designed and developed during the first project year, together with EVIDES industriewater B.V. and Innovation Engineering & Construction N.V. (IEC NV) as pilot builder. During the following 2 project years, on-site testing will be performed on 3 industrial chemical sites : Dow Benelux BV, Yara Sluiskil BV and BASF Antwerp NV. Project communication is managed by "i-cleantech Vlaanderen" and "Het Vlaams Kenniscentrum Water (VLAKWA)" for the region of Flanders, while "Stichting Kennisuitwisseling Industriële Watertechnologie" manages this for the Netherlands. Knowledge centra like HZ University of Applied Sciences and Ghent University will both contribute for the research part, the technological innovations and the optimisation process.

Objectives

•    Build 3 plug & play mobile units for water resource recovery in chemical industry
•    Test and demonstrate industrial water reuse on-site
•    Develop strategies for water treatment of the future by analyzing and processing data

December 2017: continuous testing at Yara has started

In September 2017, the mobile infrastructure of module 1 has been placed on site at Yara Sluiskil B.V. The building and the programmation of the installation was finished by november 2017. In December 2017, the first continuous tests for Yara Sluiskil B.V. started with the installation that can run fully automatic.  Ghent University and HZ University of Applied Sciences are working closely together for the daily operation of the installation.
The first stream which is now being tested at Yara is a processcondensate containing ammoniumnitrate. On this stream, reverse osmosis (RO) elctrodialyis (ED) and membrane distillation (MD) are being tested. Research is performed on desalination of the stream and on the quality of the produced water.
