NF membrane+ RO membrane system


Nanofiltration system


The RisingSun nanofiltration membrane has a molecular weight cutoff between the reverse osmosis membrane and the ultrafiltration membrane, approximately 200-800 daltons. Retention characteristics: preferential retention of divalent and polyvalent anions, and the rejection of monovalent ions is related to the concentration and composition of the feed solution. Nanofiltration is generally used to remove organic matter and pigments in surface water, hardness in groundwater and partially remove dissolved salts, and is used for the extraction and concentration of substances in the production of food and biopharmaceuticals. The operating pressure of the nanofiltration membrane is generally 3.5-30 bar.

 

Nanofiltration membrane material: polyamide, sulfonated polyether sulfone, sulfonated polysulfone.

 

We offer a variety of fine molecular weight roll-off nanofiltration membrane elements with a compact structure and reasonable surface area/volume ratio. Through the use of different flow channel networks, (13-120 mil) can change the width of the material liquid flow channel to adapt to a variety of viscosity of the liquid. In order to meet the application of certain special industries, we can provide acid, alkali, high temperature, anti-pollution film products.

 

Advantages: high thermal and chemical stability

Import raw materials to ensure high quality

Simple replacement of membrane modules

 Various sizes of membrane elements are available

 The membrane core packing density is high, and the unit membrane area cost is low

No dead angle design, not easy to pollute

 

Applications: Clarification of fermentation broths in pharmaceuticals and bioengineering

Clarification of biochemical lysates

Suspended material removal

MBR sewage treatment

RO/NF preprocessing


Reverse osmosis system


The reverse osmosis membrane can retain more than 0.0001 micron material, and it is the finest membrane separation product. It can effectively retain all dissolved salts and organic matter with a molecular weight greater than 100 while allowing water molecules to pass through. Reverse osmosis membrane material: polyamide, unique composite membrane.

 

We use imported high-quality reverse osmosis membranes to produce standard pressure, low pressure, ultra-low pressure and seawater desalination roll reverse osmosis membrane elements, which are compact and have a reasonable surface area/volume ratio. Through the use of different flow channel networks, (13-120 mil) can change the width of the material liquid flow channel to adapt to a variety of viscosity of the liquid. In order to meet the application of certain special industries, we can provide thermal disinfection, sanitary grade, high temperature and anti-pollution film products.

 

Advantages: high throughput, low energy consumption, long life
