3AWater – Trace metal detection for improving industrial water management

3AWater was established by nanotechnology and spectroscopy professionals in January 2019 in the land of thousand lakes in Kuopio, Finland. The concept and the first prototype of the 3AWater Multimetal Water Analysis System (MWAS) was developed at the Department of Applied Physics, University of Eastern Finland few years earlier. There was several tens of years of combined research even before that which led to this innovation. Read more about our story on our blog.

After incorporating 3AWater, the knowledge, research results and immaterial right were transferred to the company. 3AWater spent the next three years on research and development to improve the accuracy, reliability, and user experience of the product.  We analysed several thousands of artificial and real water samples and created a comprehensive data set to ensure the reliability and accuracy of our analysis. After intense development, the MWAS was launched in the beginning of 2022. We are proud to say that the usability was optimized to the very detail and we believe this is one of the most user friendly chemical analysis systems ever build.

The motivation of the founders of 3AWater was to create a concrete and useful product from the years of academic research. We wanted be part of the change for more environmental-friendly society by providing the industry tools to optimize their production while keeping the environmental impact to minimum. The fast, easy and accessible water quality monitoring technology we provide is essential to monitor, regulate and treat industrial waters in order to prevent pollution of waters, to remediate already polluted waters, and to make sure potable waters are clean and safe for consumption or irrigation.


Sustainability and environmental responsibility – The purpose of 3AWater is to create value to our customers and stakeholders in the domain of sustainability and environmental responsibility. Our focus is to help our customers to be part of the change towards more sustainable industrial operations. In addition, we are striving to make our own operations more sustainable and demand environmental responsibility from our subcontractors and partners.

Reliability – Reliability is the key aspect of any analytical tool. This includes both reliability of the analysis results and minimizing other sources of errors including human errors. Our philosophy behind the technical development is that anyone should be able to make the reliable analysis in any conditions without extensive training, frequent calibrations, blank measurements, rinsing and cleaning steps and other maintenance work typically involved with analytical equipment.

Trust – We understand the value and risks involved in the water quality data produced by our products. The confidentiality of any such data is our priority. Our customers can choose whether or not they want to use the IoT connectivity and data transfer to external cloud service or to only store the data locally.

Collaboration – We are aiming for long term customer relations and want to ensure the best experience for our customers. Industrial waters can vary significantly which can make the on-site, as well as standard laboratory analyses, quite complex. Therefore, we always want to make sure our systems work well with customer’s waters and fulfils their specific needs. We are willing to go the extra mile to offer the best possible performance in each customer case.

Scientific knowledge – We are scientists who believe in education and open communication. Therefore, we are publishing our scientific work related to our technology with our academic collaborators, releasing educational blog posts and collaborate with universities and educational centres. You can find the latest open access publication about early prototype of our product here:
