Increasing global concern on clean water scarcity and environmental sustainability drive invention in water reclamation technology. Laundry wastewater reclamation via membrane technology faces the challenge of membrane fouling. This paper assesses a tilting-the-filtration-panel filtration system for the treatment of real laundry wastewater filtration aimed for water and detergent reuse. Results showed that the panel tilting significantly improved fouling control and enhanced permeability due to enhanced contact of air bubbles with the membrane surface, which induced continuous detachment of foulant from the membrane surface. The combination of aeration rate and tilting angle resulted in up to 83% permeability enhancement from 109 to 221.4 ± 10.8 (L/m·h·bar). The system also offers 32% detergent recovery. Overall findings suggest that the system offers an attractive approach for both fouling management and detergent recovery and can potentially be applied under a simple setup in which filtration can be driven by gravity/hydrostatic pressure.
全球对清洁水短缺和环境可持续性的关注度不断提高，推动了水回收技术的创新。通过膜技术回收洗衣废水面临着膜污染的挑战。本文评估了一种倾斜过滤板过滤系统，用于处理实际洗衣废水，旨在实现水和洗涤剂的再利用。结果表明，由于气泡与膜表面的接触增强，促使污垢从膜表面持续脱离，过滤板倾斜显著改善了污垢控制并提高了渗透率。曝气速率和倾斜角度的组合使渗透率从109提高到221.4±10.8（L/m·h·bar），提高了83%。该系统还能回收32%的洗涤剂。总体研究结果表明，该系统为污垢管理和洗涤剂回收提供了一种有吸引力的方法，并且有可能在简单的设置下应用，其中过滤可以由重力/静水压力驱动。
