Company description

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). Though no longer a Director, Philip Davies continues to be involved as technical consultant and observer on its Board. The two main anticipated markets are groundwater treatment and recovery of valuable resources in the mining industry. Desal Solutions is now trading as 'Salinity Solutions Ltd'.

Salinity Solutions develops a desalination system, designed to be more energy efficient than standard systems.

The company employs 7 full time staff and 15 part time staff, including 4 full time scientific posts.
