Water Pollution Monitoring

Phosphorus and nitrogen (in the form of phosphates, nitrates and nitrites) are the main cause of water pollution affecting the quality of our drinking water and impacting water sports, angling, wildlife conservation and tourism as well as our health.

Water pollution management of rivers and waterways requires real-time monitoring and intervention using remote, in-situ monitoring systems. Although there are several remote water pollution monitoring systems for nitrogen and orthophosphate, there is nothing capable of remote, in-situ measurements of total phosphorus – a key pollutant that drives algal bloom (eutrophication) in rivers, waterways and lakes.

Oxford HighQ is developing a stand-alone nutrient sensor based on our expertise in chemical sensing and utilising our Optical Microcavity Analyser (OMCA) technology, which will allow the remote measurement of nitrates and total phosphorus to well below the current legal requirements at a cost point competitive with existing water monitoring equipment.

The extremely small size of optical microcavities coupled with microfluidics makes our sensors small and compact, requiring significantly less reagent and sample volume and reducing power consumption, allowing a device capable of remote, in-situ measurements with reduced cost of ownership.

Prototypes are under development and product launch is planned during 2021.
