Technology Development

E4Water will bring clear advances in relation to the current situation developing innovative methods and technologies addressing the following broad lines of action:

  • Development of innovative treatment technologies for complex (concentrated) wastewater streams.
  • Development of selective treatment technologies and treatment trains unlocking barriers for recycling and reuse of industrial water streams.
  • Stronger integration of eco-efficient water management in industrial processes.
  • Integrated water management networks to reduce freshwater withdrawal.
  • Demonstration and evaluation of innovative water management options on industrial sites, related to various chemical sub-sectors all over Europe using a wide range of new treatment technologies.
  • Full eco-efficiency evaluation of resulting integrated water systems.

 

Technology development objectives:

  • Reduction of fresh water intake by more than 40% through the enhancing of water recycling in the cooling circuit.
  • Recycling of up to 100% water into the process without any significant impact on the performance of the products.
  • Improved treatment efficiency of membranes for complex organic pollutant streams combined with reduced energy & treatment costs (20 %).
  • Enable the symbiotic reuse of mild desalinated water in chemical industry and agriculture for less than 0.40 €/m3.
  • Substitute the high energy consuming reverse osmosis – evaporation treatment train for brine treatment to achieve zero liquid discharge.
  • Valorization of inorganic concentrate streams by (I) recovery of inorganic compounds, (e.g. sulphates, phosphates, chlorides, and carbonates of calcium, magnesium, potassium, or barium) (II) recovery of the energy content from concentrated salt streams.
  • Valorization of organic concentrate streams by enabling the direct recycling of these streams in production processes.
  • Valorization of organic concentrate streams by generating valuables as side product out of wastewater treatment.
  • Symbiotic treatment of high load organic (> 6000 mg/I COD) wastewater streams coming from industrial fermentation processes to enable recycling as process water.

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