    Tips On Designing The Proper Aeration Diffuser Membrane

    We approach challenges holistically to create cutting-edge, customized solutions. A crucial first step in this process is real world field testing. Why? Because distinct rubber compounds react differently in distinct waste streams. Given the unique chemical makeup of any waste stream, we can optimize rubber compounds, and by testing it in your unique application, we can design the proper aeration diffuser membrane materials needed for optimal performance and energy efficiency.
