Water and wastewater treatment using patented self-cleaning UV technology. Non mechanical (no levers or wiping arms), not a chemical coating - unique, using the flow of water, reduces servicing interval to once a year in most applications.Patent protection in key regions including Australia, USA, India, China and New Zealand. Water scarcity, lack of clean drinking water and sanitation are issues that hold widespread concern. It is a broad market that also attracts a great deal of humanitarian funding – our technology provides proven, effective, low maintenance technology for both water and sanitation. The potential of our technology has not been realised. It has had limited market exposure (mainly in SE Qld) with small-lot local manufacturing and limited marketing (mainly "word-of-mouth"). Looking for interested parties to commercialise. Due to ill-health, the preferred avenue is sale of IP portfolio.
