Case study 2 - Solvic NV, Belgium

Enhance the water reuse by global management and synergy identification on a multi-company site

Led by Solvic, Belgium

Situation: Wastewater and cooling water streams with inorganic loads (up to > 5000 mg/l salts) and variable flows (25 – 120 m³/h) and enabling synergy effects with neighborhood industries in the Port of Antwerp Chemical Cluster. The site is located in a coastal region and faces pressure on fresh water uptake by regulatory demands (Flanders “Integral Water Policy” and “Rainwater Decree”).

Industry site characteristics: Pressure on fresh water resources. Regulatory demands. Treatment of high inorganic loaded wastewater, recycle for high quality use, facilitate use of reclaimed water.

Success indicators: Reduce freshwater dependency by up to 50%. Reduce energy demand. Realize symbiotic link to neighborhood industry. Economic feasibility.

Objectives:

The aim is to come to a water management concept that is close to zero salt waste and zero liquid discharge.

  • Scenario evaluation and step wise implementation of innovation plan to reach gradual reduction of drinking water intake from 20% to 60%.
  • Reduction of emission load in final effluent by replacing waste-generating steps or applying advanced treatment options for concentrate streams (application of waste design and zero waste concepts).
  • Transition of demo unit into ‘Industrial experimental garden’ to serve as open infrastructure to enhance innovation with regard to water reuse in the chemical sector leading companies to a symbiotic cooperation in terms of reuse.

The most efficient technology solutions will be demonstrated on-site at case study site 2 in a modular demonstration unit (industrial testbed). The applicability to neighborhood industries wastewater streams will be tested here as well (open innovation approach).

This project has received funding from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement n° 280756.
