UROS and Sensmet bring remote, real-time water quality monitoring innovation for mining industry

May 31, 2021

UROS and Sensmet aim to optimise process water recycling by studying how real-time big water data from multiple sources can be employed to save energy and chemicals, stabilise process water conditions and to improve the end-product quality.


May 31st, 2021 - Oulu. UROS has worked together with Sensmet, a Finnish company building real-time water analyser technologies, and the University of Oulu, to pilot real-time remote water quality monitoring technologies for mining use cases. 

The successful pilot was completed in March with a set up at the Oulu Mining School Research Center (OMSRC), an infrastructure complex comprising a diverse set of equipment, especially for training and research related to different stages of the extractive industry value chain (geology, geophysics, mining technology and enrichment technology). In the pilot, UROS Sense sensors were installed in various points of a Conditioner and Flotation circuit to remotely monitor changes in overall water quality, while Sensmet’s µDOES™ Multi-metal Water Analyser device sampled chemical concentrations. 

The accuracy of the data generated by Sensmet μDOES® allows the definition of a baseline, which can be correlated using statistical and machine learning models with the electrochemical fingerprints of the UROS Sense sensors. The possibilities for forecasting are stronger than ever before owing to the sheer amount of physicochemical parameters extracted. 

Remote, real-time monitoring presents several opportunities for the mining industry.

Due to the broad use of water in mining operations, quality monitoring is an integral component of environmental management programs. Currently, most water quality monitoring is conducted by collecting field samples that are subsequently transported to a laboratory for analysis. This is often slow, costly and sensitive to human error. 

Remote, real-time water quality monitoring presents several opportunities for improving on this approach. Operational costs can be reduced, contamination errors can be minimized, and health and safety risks can be mitigated, particularly when personnel are required to collect samples in remote locations. Real-time water quality monitoring also enables a significantly greater representation of water quality, as opposed to the snapshots provided by grab sampling. 

Potential for future growth

UROS Senior Director Hannu Nikurautio says, “This successful pilot at the Mining School is a great achievement for the collaboration between UROS, Sensmet and the University of Oulu. The University of Oulu is a highly recognized institution within industrial IoT and we are excited to work with their teams to enable new innovations for mining.”
