Philip Davies founded Desal Solutions Ltd to exploit high-recovery desalination technology invented at the University of Birmingham. It is targeting markets in the water supply, water reuse, and mining sectors. The spin out initially received a £210k grant from Innovate-UK along with £100k investment from Clean Engineering Ltd, Coventry. More recently, it has secured funding commitments of £750k in its first funding round, increasing its value from £1M to £2.5M, and enabling it now to employ several people including two-full time engineers (CTO and Product Engineer).
