SolarSpring provides treatment solutions for wastewater volume reduction as well as water and ressource recovery.

A key technology within the portfolio of processes is the rEvap membrane evaporator technology, a self- developed system based on membrane distillation. Together with state of the art water treatment techolgies rEvap greatly enhances the range of treatment possibilities, especially for challenging industrial wastewater applications which previsously could not be processed sufficiently.

With rEvap, ingredients from industrial effluents can be concentrated to a reusable level and can be fed back into the industrial process together with the clean water obtained in the process.

Industry Segments:

Metal industry

Brine Treatment

Zero or minimal liquid discharge
Recovery of process salts
Volume reduction of high salinity wastewater

Ammonia removal

Ammonia removal from municipal wastewater
Simultaneous conversion of ammonia to fertilizer
Ammonia removal from industrial/pharmaceutical effluents and production processes

Oil and Gas

Volume reduction of wastewater
Reuse of purified water
