Membrane filter presses continue to serve as key equipment for solid–liquid separation across a wide range of industrial applications. Their performance is strongly influenced by the mechanical integrity, chemical resistance, and dynamic behavior of the membrane materials used for squeeze dewatering. The AURUM Membrane Squeeze Technology introduces a novel material concept engineered to address the principal degradation mechanisms observed in conventional polypropylene, thermoplastic elastomer, and rubber-based diaphragms.
Comprehensive material characterization and field-testing show that the AURUM membrane exhibits markedly enhanced abrasion resistance, improved flexural fatigue stability, and reduced susceptibility to thermo‑oxidative ageing. A further distinguishing feature is its significantly accelerated inflation kinetics up to a factor of three compared with standard diaphragms. This contributes to shorter filtration cycles and increased productivity. This study provides insights into mechanical and process‑relevant properties of AURUM relative to established membrane materials and diaphragm filter plate design.
The extended service life and reduced maintenance frequency associated with AURUM yield measurable decreases in operational expenditure and enhance long‑term process reliability. The findings demonstrate that the AURUM membrane constitutes a technically robust and economically advantageous advancement in membrane filter press technology.
