CWSL was set up specifically to develop the advanced oxidation process. Since the company was established by Dr Andrew Sneddon (Managing Director) and Mr Jonathan Miles (Commercial Director) in 2001, CWSL has developed the AquaPurge ® process to the point of commercial exploitation. In addition to AquaPurge ® the company is continuing with R&D activity and is further developing the Advanced Oxidation Process (AOP) including the use of catalysts. Further product development will also include improved filtration media as a pre-treatment for AOP.
