Membrane separation and filtration equipment

I. Background of Membrane Separation Technology

Specialty Separation Membranes: Thin film materials that achieve substance separation under harsh environments such as high temperatures, solvents, and chemical reactions through their special structure and properties.

Characteristics: Achieving substance separation under harsh conditions is one of the common technologies for energy conservation and emission reduction in process industries.

II. Main Membrane Materials

(1) Ceramic Membranes

After three generations of production line practice, large-scale production capacity has been formed. Three types of ceramic microfiltration, ultrafiltration and nanofiltration membrane products with more than ten specifications are produced. It accounts for more than 60% of the Chinese market.

(2) Molecular sieve membranes. my country's first industrial demonstration unit for NaA molecular sieve membrane dehydration was built, saving approximately 65-75% in processing costs compared to traditional caustic soda dehydration technology, creating significant economic and social benefits for enterprises.

It has been successfully applied to the dehydration and recovery of solvents such as methanol, ethanol, isopropanol, and butanone in multiple enterprises, with over 50 sets of the unit widely used.

(3) PVDF hollow fiber membrane

MBR membrane characteristics:

High strength, no fiber breakage, strong chemical resistance, long service life

Uniform 25nm membrane pores, high separation accuracy, good anti-fouling performance

Burst pressure greater than 0.6MPa, the separation layer is firm and does not peel off

Regularly arranged membrane fibers, less sludge accumulation, stable high flux

III. Application Areas: 

It has been applied in water resources, energy, environmental protection, and traditional industry transformation, with over 2,000 projects implemented and nearly 1,000 enterprises served. It has generated economic benefits of tens of billions of yuan.
