Abstract
Due to its diversity, the dairy industry is one of the most important industrial sectors worldwide its products produced from this industry including milk, yogurt, cheese, butter, and ice cream. Dairy wastewater can be treated in individual ways, including contaminant reduction through flocculation, depth filtration, flocculation, etc. These traditional treatment methods have mediocre performance, making membrane technology a promising method of water utilization. According to this strategy, the techno-economic feasibility of separation lactose-whey protein using integrated membrane technologies and water recovery was examined in this study. This study focused on a UF/RO hybrid system in a laboratory scale experiment to measure milk component removal performance. Enhanced results for lactose-whey protein rejection up to 99% were reached with modified UF membranes. Antifouling nanoparticles of TiO2 and ZnO show high fouling resistance for reversible and irreversible fouling compared to the commercial membrane. SEM morphology was used to characterize UF and RO membranes that show the surface and different layers of membranes. Modified UF membranes observed a significant improvement in the percentage of mixed dairy wastewater rejection. It demonstrates major advancement in resource recovery for a valuable by-product like lactose using a scalable, low-cost UF membrane and demonstrates that multistage UF membranes may be used without RO and operated at low pressure as a cost-effective technological package.
