Why Membrane Distillation?

It’s an excellent technology for solar applications with typical operating conditions of 80°C at ambient pressure. It’s a thermal membrane process that separates water from aqueous solutions using vapour pressure as a driving force. A water-repelling (hydrophobic) membrane retains heated aqueous solution but allows steam to permeate and condense as distilled water.


Desalination Systems

Modular Membrane Distillation Systems
Based on membrane distillation technology, MMD systems are relatively feedwater independent, low-fouling, and low maintenance. Solar thermal or waste heat energy is used to attain optimal operating temperatures of 80-85°. PV powered pumps circulate the water at the pressure of 1 bar in the system. Using SolarSpring MD modules, configurations can be scaled to user needs from 1 m3 to 10 m3 per day.  Systems can be configured with heat storage tanks for constant water production.The benefits of membrane distillation make MMD systems the appropriate choice in a wide range of domestic and industrial water applications.


Our innovative Oryx150 Remote Desalination Systems provide high quality drinking water to remote and rural areas. These systems use membrane distillation technology to distill water from brackish and seawater sources. Automatic operation, low maintenance and stand-alone system design are features of Oryx150 Remote Desalination Systems. Systems are currently in operation from Mexico to Australia.

Purification Systems

SolarUF Ultrafiltration

Market leading solution for the treatment of contaminated surface water from wells, rivers and lakes. SolarUF purifies water using PV solar energy. Each unit operates autonomously and safely removes all harmful bacteria and viruses. Automatic back-flushing and innovative energy management make the system easy to run, low maintenance, and ideal for remote applications. Each SolarUF system is steel based making it secure and tamper-free. SolarUF purification systems are currently in operation in Colombia, India and Peru.

SolarUV Disinfection

Our chemical free SolarUV-Disinfection Systems provide safe drinking water to remote and rural areas. Completely solar-powered, they’re perfectly suited for applications where surface or ground water with low or no turbidity is available but contaminated. SolarUV-Disinfection Systems can be used as a standalone solution for direct drinking water production. Automatic operation, low maintenance and high security standards are the features of SolarUV-Disinfection Systems. Systems are currently in operation in India, North Africa & Middle East.

SolarAO Disinfection

The SolarAO Disinfection system generates a disinfectant that ensures that water can be stored and transported risk-free. The level of chlorine can be adjusted according to the requirements and taste preferences. Automatic operation, use of no additional chemicals and solar off-grid operation make it extremely low maintenance and easy to use. This system is highly recommended when drinking water is stored or sold. This can be the case in a rural setting where villagers travel to the plant and use their own containers or when it is sold e.g. through the prepaid water tap system. It guarantees the provider or seller of the water will not beheld accountable for recontamination of the water as it will stay drinkable for a reasonable amount of time. 

The SolarAO Disinfection system guarantees that water will not be recontaminated or germinated when stored or transported in a separate container. This system, based on Anodic Oxidation, has been developed by Autarcon GmbH and can be combined with all other systems.

Agricultural Offering

We support farmers with desalination and Biochar units so arid communities can address food and water simultaneously at a low cost and using a zero carbon tech. We provide product water with our machines as well as supporting agricultural growth. Biochar helps plants retain 80% of their water in arid regions.
