Rinocloud’s Hydrolight can detect even tiny single cells that should not be present

A sensor system that can for the first time detect E.coli bacteria in contaminated water and enable remote monitoring of supplies has been developed by Irish scientists.
The Hydrolight, developed by Cork-based scientific data management company Rinocloud, is accurate and quick, and its sensitivity means it can detect even tiny single cells that should not be present in clean water.
The buoy has a radio sensor to convey data from samples and uses artificial intelligence technology so large volumes of information can be processed in real time. The presence of E.coli in water, which can cause serious illness, can be detected with 99.3 per cent accuracy in just 3.37 seconds.
This contrasts with current standard test detection times of five to seven days, which can lead to delays in issuing boil-water notices. In some cases the threat of waterborne illness has passed because of such delays.
Rinocloud, which has developed the buoy with the help of the Environmental Protection Agency, Cork IT and Enterprise Ireland, was acquired by international biotech company Integumen in a €3.5 million takeover earlier this year.
- Boil-water notices: 'People's patience is wearing thin'
- Raw sewage from 36 areas released into Irish waters daily
- Boil water notice affecting 600,000 people lifted with immediate effect
The breakthrough is the culmination of three years’ work, its managing director Fin Murray explained, and because they are now owned by Integumen Plc, details will be announced to the London Stock Exchange on Wednesday.
The deployment of what are now patented as “wireless RAWTest Buoys” in water treatment plants would be a world first, he said, as it would reduce the average length of time water would be shut off in the event of contamination, reduce “boil-water” notices and restore supply and biological quality in more timely fashion.
