● Product performance and characteristics
The polyethersulfone ultrafiltration membrane elements used for selective separation have molecular weight cutoffs of 4 KDa, 6 KDa, 8 KDa, 10 KDa and 20 KDa respectively, which can effectively intercept various substances with different molecular weights while allowing substances with smaller molecules and solvents to pass through, achieving efficient material separation. This series of ultrafiltration membranes adopts unique membrane materials and manufacturing processes, which makes it have excellent chemical resistance and mechanical strength, ensuring stable operation in a wide range of harsh environments.. It has broad applications: In the field of biopharmaceuticals, it can be used for the separation and purification of biomolecules such as proteins and enzymes to improve product quality and safety. In the food and beverage industry, it can be used to clarify and concentrate fruit juice, beer, dairy products and other products to improve the taste and nutritional value of products. In the field of environmental protection, it can be used for the purification and pretreatment of drinking water, municipal water and various industrial water, so as to realize the resource utilization of wastewater.
