Technology description

XerChem’s new BioControl unit combining membrane technology and electrolysis is made for in-situ biocide production. Unit is based on the BioControl concept developed by VTT. Existing in-situ units use saturated brine solution, while BioControl unit uses existing chlorides from process water, which means that transport or storage of hazardous substances is not needed. In situ biocide production also helps to minimize the amount of chemicals introduced in the water circuits and limit the risk of detrimental impact on thewaste water treatment plant.

Development status

BioControl unit has been piloted at a Finnish paper mill since February, 2019 and also at Finnish steel mill since August, 2019.

SpotView project

BioControl unit has been developed during SpotView project. SpotView project has started on November 2016 and ended on April 2020. The objective of the SpotView Project was to develop and demonstrate innovative, sustainable and efficient processes and technology components, in order to optimize the use of natural resources, especially water, in three industrial sectors (Dairy, Pulp and Paper and Steel).
