Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand.

Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential contaminants. This project will develop technology using AlGaN/GaN-based transistors, sensitised to different contaminants, enabling multi-analyte real-time sensor arrays. In situ monitoring systems based on such arrays will be fast, accurate, reliable, low-cost, and applicable to a broad variety of water recycling projects.Read moreRead less
