Our mission

The mission of Sloan Water Technology Ltd. is to deliver societal benefit through commercial products based on fundamental research that is developed into game-changing innovations in fields related to sound, air and water. The exchange of ideas and techniques between engineers, medics, microbiologists and experts in food, health, physical and social sciences, from defining the problem to validating the solution, shapes the products for a wide range of sectors. 

An innovative partnership

Professor Timothy Leighton, Professor at the University of Southampton, and Sloan, the world’s leading commercial plumbing systems manufacturer, join forces to create Sloan Water Technology, Ltd.

Sloan supports and funds Sloan Water Technology’s research and development. SWT combines acoustic fields in water with microbubbles for cleaning and decontamination, infection prevention, and recovery from wounds and ulcers, without promoting antimicrobial resistance. SWT's inventions also aim to support the provision of clean food and water.

Located in Romsey, Hampshire, England, Sloan Water Technology's inventions for supporting healthcare, industry and the environment complement Sloan’s existing efforts in developing hygiene-friendly commercial restroom products and applications.
