Industry


SolarSpring GmbH from Freiburg has developed a solution for the recovery of resources based on membrane technology.

With rEvap, ingredients from industrial rinsing solutions can be concentrated to such an extent that they are reusable and can be fed into the industrial process together with the clean water obtained in the process. Energy and material cycles are thus closed and industrial processes are made more sustainable. The rEvap is designed for use in industrial water recycling and is ready for market entry.

Companies in the metal processing industry, textile and food industry as well as agriculture successfully use our technology and products for wastewater treatment and recycling as well as for the complete recovery of resources.

Metallurgical industry

  • Recycling of acids
  • Nickel recovery
  • Treatment of baths from various galvanic applications

Circuit board production

  • Recovery of gold and other rare metals

Polymer industry

  • Concentration of sodium chloride (NaCl) for Chloralkali-Elektrolyse

Food industry

  • Recycling and concentration of salty process waters (vegetables etc.)
