<\/p>\n

Both a dead-end and a crossflow ultrafiltration process using a PVDF membrane were tested. Both systems operated stably throughout the entire test period. Dead-end filtration achieved a recovery rate of approximately 90\u201392%. The crossflow process, on the other hand, achieved a recovery rate of around 80\u201385%.<\/p>\n

No irreversible membrane fouling was observed as the test period progressed. Periodic backwashing kept the formation of a surface layer to a minimum, thereby maintaining a constant filtration performance.<\/p>\n

Chemical cleaning of the membranes was not necessary during the entire test period.<\/p>\n

<\/p>\n

Laboratory analyses also confirmed the high quality of the filtrate produced.<\/p>\n

At the same time, the volume of the resulting concentrate was minimized in a separate experiment using separation technology. The resulting centrate can be fed back into the UF filtration process, further reducing the volume of wastewater.<\/p>\n

The results of the pilot test provide a solid basis for the design of future production plants. Due to its higher yield, compact footprint, and low energy consumption, the dead-end process in particular proved to be a promising solution for industrial applications.<\/p>\n

Based on the process data obtained, concepts featuring a modular operating mode for capacities ranging from 2 to 15 m\u00b3\/h have already been developed.<\/p>\n

July 13, 2026. The treatment of process wastewater is becoming increasingly important, particularly in the semiconductor industry. A recent pilot study on the ultrafiltration of silicon-containing process wastewater has now shown that cost-effective and technically stable treatment is possible. Over a two-week period, various filtration modes were investigated under real-world process conditions. The focus was on how to efficiently purify process wastewater containing silicon particles and treat it for potential reuse. The wastewater examined had a comparatively low solids concentration of approximately 200\u2013400 mg\/l.
