Nanofiltration membrane, as the name suggests, refers to a membrane with "nanoscale pores", which is between ultrafiltration and reverse osmosis, and has a certain retention rate for inorganic salts. The molecular weight of organic matter retention can be selected from 200 to 1000 Dalton.

Traditional processes such as centrifugal separation, vacuum concentration, multi effect film evaporation, and freeze concentration have to varying degrees constrained the improvement of product quality, while product costs cannot be effectively controlled. Currently, they have been gradually phased out and replaced by new nanofiltration membrane technology.

1. The core membrane components adopt original imported organic membranes, and different membrane forms are selected based on process technology requirements and user specific needs to ensure the retention performance of internal membrane components in different systems, membrane flux, and the stability and reliability of the entire membrane system operation.

2. Bona's nanofiltration membrane system can synchronously achieve desalination and concentration of materials under low operating pressure, with a short production cycle and thorough desalination. The resulting product has high purity and good quality stability.

3. According to the specific needs of customers, the permeate through the nanofiltration membrane can be recovered, and the membrane components can be restored to their ideal performance after professional cleaning, fully realizing the economic efficiency of the membrane equipment.

4. The processing process is always at room temperature and has no phase change, without any adverse effects on the effective components in the material. It is particularly suitable for the treatment of heat sensitive substances, and the resulting product has a high content of effective components. According to process requirements, it can continue to enter the next section or directly undergo drying treatment.

5. The system adopts a fully enclosed pipeline operation, made of sanitary grade stainless steel, and the work site is safe and hygienic, which can meet the standardized production requirements of GMP or FDA.

6. Due to the lack of phase transition during the system processing, it remains at room temperature, resulting in low energy consumption and low operating costs.

7. High degree of process integration, reasonable layout, fully automatic control, online monitoring of important process parameters, and real-time monitoring of system operation status. Professional on-site engineers will provide you with new system maintenance information at any time.
