Spiral Wound Membrane
Suntar has the ability to provide a multitude of spiral wound membranes with different pore sizes ranging from microfiltration to reverse osmosis to fit different needs.
With a molecular weight cutoff (MWCO) of 1000 to 300000, spiral wound ultrafiltration membrane retains large molecules while allowing target product through; or retains target product but allowing water together with small molecule through to achieve colour and impurities removal, as well as product classification. Spiral wound nanofiltration membrane has a MWCO between 200 and 1000. It allows above 90% permeance of NaCl in water and is suitable for multiple purposes such as salt removal, monosaccharide removal and concentration. Reverse osmosis is widely used in water treatment to remove impurities such as inorganic ions, bacteria, viruses, organic compounds and colloids to obtain high purity water.
As one of the pioneers in membrane separation technology, Suntar is experienced in designing, manufacturing, installing, operating and maintaining spiral wound membrane systems.

Suntar Membrane System
Electrodialysis
Electrodialysis is a dialysis process driven by an external DC electric field. Utilising the selective permeability of the ion selective membrane, (that is, cation passes through cation selective membrane and anion passes through anion selective membrane) cations and anions migrate towards the cathode and anode respectively, achieving separation of ions. In the process of ion migration, if the membrane’s charge is opposite to the charge of the ion, it allows the ion to pass and repells those that have the same charge as the membrane. This achieves the purpose of solution desalination, concentration, refinement or purification.

Graphene Membrane
Based on the patented graphene modification technology, the inner support PVDF graphene is an innovative composite of graphene technology and polymeric membrane materials. Graphene is distributed in the membrane to form a membrane frame with a strong support structure, and channels are formed between the membrane pores to reduce the water flow resistance. This allows the membrane to achieve greater flux compared to ordinary membrane fibers.
At the same time, given the rigid support from graphene, pores do not collapse when the fibers undergo drying. Additionally, capitalising on the hydrophobicity of the graphene material, the surface possesses hydrophobic groups that can effectively repel hydrophilic foulants during operation ‒ vastly improving the membrane’s anti-fouling performance

Membrane Bioreactor (MBR)
Membrane bioreactor（MBR）is a new type of wastewater treatment process that integrates advanced membrane separation technology and traditional biological treatment technology. Compared to traditional wastewater treatment methods such as activated sludge and oxidation ditch, MBR has the advantage of eliminating secondary sedimentation tanks and other process links which greatly reduces the footprint and produces stable and high-quality permeate.
By using PVDF internal support, Suntar’s MBR series products have membrane tensile strength > 200N to resist repeated air scouring. The nano-reinforced technology in Suntar’s MBR systems provides high surface permeability and easy chemical cleaning. Having reliable and stable performance, Suntar’s MBR systems are suitable for municipal wastewater treatment and industrial wastewater treatment. Suntar’s MBR systems, which have achieved several invention and utility patents, are widely applied in wastewater treatment plants.

Hollow Fiber Membrane
Hollow fiber membrane system acts as a pretreatment for reverse osmosis. It has a pore size of less than 0.1um and can remove substances with molecular weight greater than a few thousands - for example, macromolecular colloids, proteins, slime particles and bacteria. This ensures the inlet water for reverse osmosis has turbidity lower than 0.5 NTU and SDI <3 which reduces the cleaning frequency and lengthens the lifespan of reverse osmosis membranes. Outside in hollow fiber membrane module has been widely used in industrial wastewater treatment, sewage treatment, reclaimed water reuse, surface water treatment, reverse osmosis pretreatment and many other fields.

High Pressure RO Membrane
Reverse osmosis is a water treatment process that removes contaminants from water by applying pressure to force water molecules against the concentration gradient through a semipermeable membrane. It is widely used in the purification and concentration of various liquids. The most common application of reverse osmosis is water purification which removes impurities such as inorganic ions, bacteria, viruses, organic compounds and colloids to obtain high-quality purified water.
Ultra-high-pressure reverse osmosis can be utilized to further remove any water in the concentrate after the reverse osmosis and/or the high-pressure reverse osmosis process. The membrane's highest operating pressure is 120Bar at a maximum temperature of 30℃ and has the characteristics of a high salt rejection rate.

Industrial Chromatography
Industrial chromatography is an advanced separation method based on the affinity between different molecules. It is an effective method for separating physically and chemically similar materials. Different molecules in the chromatography form different attractive forces between itself and the stationary phase， leading them to have different migrating speeds in the stationary phase and separation. It adopts a multiple small unit design and achieves continuous input through an automatic switching mechanism. The long separation bed achieves higher separation and better separation effects.
Suntar’s industrial chromatography is a continuous separation technology. It is scientifically designed based on the traditional fixed-bed chromatographic separation and makes full and reasonable use of the stationary phase to achieve continuous production. It fully showcases the advantage of chromatographic separation technology to achieve high quality, high efficiency, stable and low energy consumption separation process.

Continuous Ion-Exchange
Continuous Moving Bed technology is an innovative separation process which is different from traditional fixed bed, pulse bed, simulated moving bed and other processes. The continuous moving bed system consists of resin columns and porous distribution rotary valves. The resin column series can be divided into several different functional areas. After the material enters the system, each resin column passes through each functional area through the switching of the rotary valves to achieve simultaneous adsorption, water washing, elution, regeneration and other processes. This transforms the traditional batch processes into continuous process.
Suntar’s continuous moving bed system adopts advanced design concepts and excellent production technology. It is easy to operate with a wide range of applications and can be modified flexibly based on the separation requirement of different products. Suntar has successfully developed and applied dozens of said system in different industries in China.
