Purification of recycled water – 2012-2014

Developed, built and tested a prototype with advanced purification technology that combines the use of membranes, biology and oxidation (multistage MBR-AOP technology).

Tests that were done in cooperation with Trondheim municipality showed that 75-99% of micro-organic pollutants and trace-impurities in recycled wastewater were cleansed.  The technology provided a higher cleaning effect, required less space and used less energy than similar technologies. Inrigo AS collaborated with Normex AS, with support from SkatteFunn and the environmental technology scheme at Innovation Norway.
