Research & Development

The center has the most comprehensive membrane manufacturing technologies in China and can produce a full range of membrane products including ultra-filtration membrane, spiral composite reverse osmosis membrane, spiral composite nano-filtration membrane.

Ultra-filtration membranes:

The center uses a phase inversion method to produce ultra-filtration membranes, which are made of poly (ether sulfone), polyvinylidene fluoride and polyvinyl chloride. The membrane pore sizes range from 0.1μm to 10,000 molecular weight cut-off.

The units are hollow and spiral, of which the sizes are from 4 inches (10.16cm) to 8 inches (20.32cm).

Spiral composite reverse osmosis membranes:

The center uses interfacial polymerization techniques to produce reverse osmosis membranes, which are made of polyamide and modified polyamide.

Products such as ultra-low pressure reverse osmosis, low-pressure reverse osmosis, seawater desalination, contamination resistance and monomer materials synthesis and elements are available from 4 inches (10.16cm) to 8 inches (20.32cm) in size.

Spiral composite nano-filtration: Materials for this type of membrane include polypiperazine amide and polyamide; manufacturing techniques of standardized products such as NF-40 NF-70 and NF-90 are owned.

International advanced interfacial polymerization techniques are used to produce nano-filtration membranes. Elements are available from 4 inches (10.16cm) to 8 inches (20.32cm) in size.

The center has the most powerful membrane research team and capable of manufacturing membrane products of customized functions.
