Off-Grid Water and Energy

Self-Powered Water Treatment Plant

With the support of DEG, Infinite Fingers and Membran-Filtrations-Technik (mft) have developed a renewable energy powered, remotely controllable micro-reverse osmosis water desalination plant: The RO-SEA 100.

What We Helped With

Infinite Fingers designed and developed the off-grid power unit, the controller and the web based data visualization while mft brought their expertise in reverse osmosis water desalination to the project.

The Project

The plant is supplied with wind and solar energy, which is stored in lithium-ion batteries. Weather conditions, state-of-charge of the battery etc are monitored and recorded using the Infinite Fingers Controller.
The data is sent via GSM to the Infinite Fingers server so that actionable decisions can be taken in real time by mft back in Cologne.
Controller logic has also been built into the Infinite Fingers device, enabling the unit to switch itself on/off as necessary when certain monitored conditions are exceeded (e.g., state of charge).
