We have quite wide membrane resources, there are different configurations in spiral wound, tubular, flat sheet, hollow fiber and different materials in Thin Film Composite, ceramic, metal for MF, UF, NF, RO applications, meanwhile, we can also provide specially developed membranes to deal with strong acid or caustic solutions, and liquids with organic solvent. The acid, caustic  or solvent can be recovered to decrease the discharge of these pollutants and realize cleaner production.

With the development of textile industry, the amount of textile wastewater increases. We provide a cleaner production process via membrane technology for textile industries to realize resource reclamation, energy saving and emission reduction.

Dyestuff wastewater is highly polluted with dyestuffs and salts, the wastewater composition also varies easily, and this makes it to be one of the most difficult wastewaters to be treated. We have developed a new process to treat the dyestuff wastewater, starting from modifying the production process, which is using membrane to desalinate dyestuffs, decreasing the quantity of wastewater production. And the effluents are further separated by physical treatment and MBR process, by doing so; they both can be treated easily. Furthermore the whole process operating cost is low, and the capital cost can be recovered.

Electroplating effluent contains large amount of heavy metals and is highly toxic. Suntar utilizes membrane technology to recover the multivalent heavy metals and reuse permeates in the washing process, thereby the zero-discharge for the whole electroplating process can be realized.
