FRANK – Filtered Regolith Aqua Neutralisation Kit

Developed by RedSpace Ltd, Aldershot/Cleethorpes/Richmond (North Yorkshire).

A three-stage approach designed to deliver a continuous flow of drinking-grade water in a lunar environment would first heat the lunar soil (regolith) sample in a sealed chamber to separate off volatile gases and leave a liquid of water, methanol and regolith fragments. The liquid is passed through a membrane to remove solid particles. The remaining liquid is distilled to separate the methanol from the water.
