Organic Solvent Resistant Hollow Fiber Membrane Modules.
Microfiltration and
Ultrafiltration Membrane Modules
Organic solvent compatible new separation membrane realizes process innovation.
By Unitika's proprietary polymer processing technology, we have developed the liquid separation membranes with polyamide that can be used in organic solvent systems. This feature contributes to energy saving and cost reduction in the processes such as concentration of target substances, removal of impurities and regeneration of waste solvents.
Features
- ・Contributes to energy, resource and cost saving in your manufacturing process by replacing the distillation or centrifugation processes with membrane separation.
- ・Capable of nanoparticles and dissolved polymers separation from various organic solvents.
- ・Non-heating process enables the separation of heat-sensitive components.
