Summary nanofiltration, by definition, refers to a "nano-scale holes" in the film, it is between ultrafiltration and reverse osmosis, and to a certain degree of retention of inorganic salts, organic matter molecular weight cutoff from 200 ~ 1000 Dalton optional . Traditional centrifugation, vacuum concentration, thin film multi-effect evaporation, freeze concentration and other processes, in varying degrees, restrict improving the quality of the product itself, but at the same time they can not effectively control production costs, has gradually been eliminated, will be replaced by new nanofiltration technology. Applications nanofiltration devices for industrial application started very early, and continue to accumulate in the innovation process, we get a lot of successful project experiences and these experiences will continue to promote the use of new production processes. Our nanofiltration system has been successfully applied to the food and beverage industry, the field of bio-fermentation, bio-medicine, chemical industry, water treatment industry, environmental protection industries, cost-effective way to achieve a material separation, purification and concentration! Advantages of nanofiltration system 1, the core membrane components using imported organic film, combined with the technical requirements and the specific needs of users choose to use different configurations of film form, in order to ensure the stability of the different system components endometrial interception performance, membrane flux and the entire membrane system operation and reliability. 2, nanofiltration system can operate at a lower pressure, desalted and concentrated to achieve synchronization of materials, and the short production cycle, desalination is more thorough, high-income product purity, good quality stability. 3, according to customer specific needs, you can go through nanofiltration permeate recovery and membrane components through professional cleaning to restore optimum performance membrane elements, the full realization of economic membrane device. 4, the process always at room temperature, and the process no phase change, without any adverse effect on the material in each of the effective components, particularly suitable for the treatment of heat-sensitive material, a high active ingredient content of the resulting product, according to process requirements may continue into the next station or directly dried. 5, the system is fully enclosed pipeline runs, sanitary stainless steel production, job site safety and health, which can meet the requirements of 高标准 or FDA standardized production. 6, because the system no phase change process, always at room temperature, and thus low energy consumption, low running costs. 7, high degree of process integration, rational layout, to achieve automatic control, on-line monitoring of important process parameters, to keep the system operating conditions, the professional field engineers will provide you with the latest information at any time to provide system maintenance. ?
