PRNF-S Series (Pressure Resistance Nanofiltration) High-Pressure Resistance NF Membrane is specially designed for the water quality of high TDS and COD and also can be used for the concentration and separation of high salts and high viscosity materials.

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 Nanofiltration Membrane

Waste concentrated water recovery in sugar decolorizing
Sulfate removal in the chloralkali industry
Separation of monosaccharide and disaccharide
Sugar fractionation
The concentration of peptides and proteins in cooking liquor such as sea cucumber
Desalination of whey protein
Juice concentration
Concentration of antibiotics
