IMT Masken und Teilungen AG is an industrial company in the field of glass technology. Various chemicals and solvents used to manufacture the products must be pre-cleaned on site by IMT before the wastewater can be discharged into the sewer system of the Uster wastewater treatment plant. Pre-cleaning involves a process to neutralise the wastewater. The existing neutralisation system is ageing, so IMT has commissioned TBF to upgrade the neutralisation system to the state of the art.
