Purpose and goal
In this feasibility study, the possibility to build a compact, low-cost system for water quality analysis in real-time has been investigated. The system is based on excitation and measurement of UV fluorescence from micro-organisms in water. A lab-scale test system has been developed and used to analyze water of different quality and with different contaminants. The measurements show that the method is suitable for the selected applications and was used as a basis for a suggested design and specification of a low-cost UV fluorescence water analysis system.
Expected results and effects
A literature study was conducted and used to design a lab-scale test system for measurements of UV fluorescence from water samples. The test system was used to analyse water of different quality and with different microbiological contaminants. The measurements showed good sensitivity in the different use cases and the technology was deemed suitable for further development. The results will be used to suggest a design for a simple, low-cost, system for water quality monitoring in running water. The project group was expanded and an application for a continuation project was submitted.
Planned approach and implementation
The project is carried out by RISE and two partner companies. The literature study was carried out in collaboration between the three project partners. RISE developed the test system and the group jointly evaluated the technology with test samples. The project results were communicated successfully during the course of the project and the project group was expanded for a continuation project application.
