The combinatorial optimality of membrane morphology and process parameters during dead end microfiltration of bottle gourd juice have been addressed in this article. Saw dust and kaolin based low cost ceramic membranes with varied morphology have been chosen to evaluate upon their microfiltration performance. For the chosen membranes, fresh, paper filtered and centrifuged juice samples were considered along with transmembrane pressure differential as process parameters. Combinatorial optimality was based on flux decline trends, fitness of fouling models, irreversible and reversible fouling data, irreversible permeation resistance and nutritional analysis of the permeate samples. An interesting feature of the article had been with respect to feed constitution playing a critical role in influencing the optimal choice of membrane morphology and transmembrane pressure differentials. Among all cases, paper filtered bottle gourd juice, 0.75 μm membrane and 137.9 kPa transmembrane pressure were found to be the best choice in terms of minimal irreversible fouling, lowest protein content, good clarity, good polyphenol and antioxidant activity in the permeate and appropriate flux.

本文探讨了葫芦汁死角微滤过程中膜形态和工艺参数的组合优化。选择了具有不同形态的锯末和高岭土基低成本陶瓷膜来评估其微滤性能。对于所选的膜，将新鲜的，纸质过滤的和离心的果汁样品以及跨膜压差作为工艺参数考虑在内。组合最优性基于通量下降趋势，结垢模型的适用性，不可逆和可逆结垢数据，不可逆渗透阻力和渗透物样品的营养分析。文章的一个有趣的特征是，饲料的组成在影响膜形态和跨膜压差的最佳选择方面起着至关重要的作用。在所有情况下，从最小的不可逆结垢，最低的蛋白质含量，良好的透明度，渗透液中的多酚和抗氧化活性以及适当的通量方面考虑，纸过滤的葫芦汁，0.75μm膜和137.9 kPa跨膜压是最佳选择。 。
