Detailed Introduction
Product Overview
Organic solvent-resistant nanofiltration membranes are a new type of green, efficient, and energy-saving nanofiltration membrane for processing organic solvents. They are widely used in the chemical, pharmaceutical, and food industries for material and solvent separation, drug purification and concentration, and catalyst separation. Types of organic solvents that the membrane can withstand include: alcohols, esters, ketones, N,N-dimethylformamide, N-methylpyrrolidone, etc.
Nanofiltration membranes use the pressure difference across the membrane as the driving force, relying on the pore size screening of the membrane pores and the Donnan effect (charge effect) to allow the solvent to pass through while retaining the small molecules dissolved in it. The pore size of the membrane, the surface charge of the membrane, and the size of the separated substance affect the separation efficiency of the membrane.
Product Features
1. Excellent solvent resistance and stability
2. High permeability, high retention rate, and strong anti-fouling ability
3. Suitable for alcohols, esters, ketones, DMF, NMP and other organic solvents
4. No phase change during separation, low energy consumption
5. No chemical reaction, does not destroy molecular activity
Application Areas
1. Separation of organic solvents and materials in the pharmaceutical, food, and chemical industries
2. Organic solvent recovery and purification
3. Drug concentration (antibiotics, peptides, etc.)
4. Recovery of dissolved chemicals
5. Production line cleaning wastewater, hydrocarbon recovery and purification

Product Applications
Separation and purification of pharmaceuticals in the pharmaceutical industry
Application Direction
There is a huge demand for the separation and purification of drugs in the biopharmaceutical industry. Addressing the issues of lengthy processes, high costs, and heavy pollution associated with traditional extraction and salt washing purification methods, a nanofiltration membrane purification process has been developed, significantly reducing the purification process and saving companies approximately tens of millions in operating costs annually.
Typical pharmaceutical industry solvent recovery process flow
Application Features
1. Solvent-resistant nanofiltration membrane technology can replace traditional processes such as distillation, extraction, and salt washing, eliminating the need for steam and reducing energy consumption by more than 50%.
2. Room temperature operation avoids decomposition and improves product and solvent recovery rates.
3. Significantly reduces three wastes discharge
