Pure Solvent NF Spiral-wound Membrane

 

Products of HSX Series are suitable for the conditions of the pure organic solvent. If the solvent is more than 95%, hydrophobic membrane material is used. Extraction, recovery of the solvent and reduce the difficulty of wastewater treatment and energy consumption could be conducted, and in the following solvents, it can be normally operated for 12 months.

 


Methanol, alcohol, isopropyl alcohol, ethylene glycol, acetonitrile, acetone, ethyl acetate, dichloromethane, n-hexane, THF, NMP, DMF, DMA, DMSO and toluene.

·  After operating for 24 hours, measure the average rate of desalination. Fluctuation range of flow for a single membrane element is +25%/-25%.

·  Measure Condition : MgSO4 solution of 2,000 ppm, 435psi of operating pressure, 25℃ of temperature, pH7and 15% of recovery rate.
