SolarSpring GmbH

SolarSpring GmbH

SolarSpring membrane solution GmbH is a clean-tech company based in Freiburg, Germany, providing industrial waste water Purification systems based on membrane distillation (MD) and ultrafiltration (UF) technology. We are one of the leading companies worldwide in the development of commercial products based on MD, a novel and breakthrough technology for industrial waste water applications and scientific investigations. The thermally driven process of MD is perfectly suited for the concentration and reduction of waste water streams or the separation of volatile components. The application of advanced membrane module concepts and the use of waste heat in our systems results in highly energy and cost efficient processes. In addition we offer integral solutions for decentralized water purification based on UF technology for households and small communities. Our products produce potable water from nearly any source of dirty or contaminated water and are powered by solar energy.

Year Founded:

Founded in 2009 as a spin-off of the Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany, the SolarSpring GmbH, membrane solutions has grown into a world market leader for membrane distillation technology.


Companies active in the metallurgical industry, applying zero liquid discharge (ZLD) systems or treating waste water will successfully be able to use our products for water and process solution treatment and recovery of valuable resources.

Communities, Hotel Resorts and Private Households profit from our water treatment systems, rain water purification and the supply of drinking water at a high quality. We have installed systems in India, Columbia, Peru, Spain and Afrika.

Research Institutes, Universities and Labs use our membrane distillation equipment for their own research and analyses for which we provide support if requested. Some of our research systems are located in Qatar, Riad and Spain.

Where conventional waste water treatment methods reach a dead end or the disposal of process fluids exceeds the financial scope, we bring in our membrane distillation technology. Or in case you are located far away from any infrastructure, our solar powered filtration systems might very well save your day, even if the water source is contaminated with viruses and bacteria.
