Organic Solvent Resistance Nanofiltration membrane elements are suitable for the coexistence environment of organic solvents and water, utilizing the hydrophilic membrane materials, which can maintain normal work continuously for more than 12 months in the following solvent. It can be used for purifying and recycling solvents, as well as reducing water treatment difficulty and energy consumption.

Typical Chemical Solvents

Typical organic solvents are methanol, ethanol, propanol, ethylene glycol, acetonitrile, acetone, ethyl acetate, dichloromethane, n-hexane, tetrahydrofuran (THF), methyl pyrrolidone (NMP), dimethylformamide (DMF), dimethyl adipate (DMA), dimethyl sulfoxide (DMSO), and toluene and so on.

Storage Conditions of Nanofiltration Membrane

Before the first use, all membrane elements must be stored under the original packaging conditions.
The membrane is best placed in the original packaging and opened before the use of the water treatment system.
The transport temperature below 0°C may cause irreversible membrane damage and the transport temperature above 30°C may cause membrane degradation and deterioration of the protection solution.
Store in a cool, dry condition and a place that is not directly exposed to sunlight or artificial lighting. Storage temperature stays at 0°C to 30°C, and the longest storage time is 6 months.

General Information of Nanofiltration Membrane

Once wetted, the membrane element must always be wet.
The limited warranty we promised will expire due to the fact that the user does not strictly follow the operational restrictions and guidelines set forth in this Code.
If the system is in a shut-down state for a long time, the membrane element is advised to be placed in the protective solution to prevent the growth of microorganisms.
It is the user's responsibility if uses an incompatible chemical and lubricant, and causes undue influence on the original.
The maximum allowable pressure drop of the single-pressure vessel is 60 psi (4.1 bar).
At no time can the backpressure be produced on the side of producing water to avoid the occurrence of harmful problems.

Typical Application of Solvents Resistance Nanofiltration Membrane
• Paint coating: Purify the waste liquid used in the cleaning of the production line, and recycle valuable solvents and coatings
• Medicine: Purify concentrated drugs and intermediate products in the solvent mediums (e.g.: 6-APA)
• Recycling of antibiotics and peptides
• Recycle dissolved chemicals
• Solvent purification
• Recovery of polymer binders and separation of pigments
• Recovery of catalyst from the solution
• Recovery of hydrocarbons during the cleaning process
