Faced with high IEX process waste disposal costs, TRUMPF, a manufacturer of laser diodes made from Gallium Arsenide substrates (GaAs) wafers, undertook efforts to optimize the IEX process and produce less hazardous waste. One of the process improvements included the installation of the MetalGuard Arsenic online arsenic analyzer to continuously measure influent and effluent arsenic levels in real-time, providing TRUMPF with a stream of accurate and reliable arsenic data to measure the performance of its IEX system and ensure regulatory compliance. Timely and accurate arsenic results enabled TRUMPF to optimize rinse water reuse as well as to optimize and reduce IEX backwash frequencies, increasing media performance and reducing hazardous waste generation. These process improvements have resulted in an estimated annual cost savings of $100K for the facility.
