Large amounts of wastewater are generated by some processes used to extract underground crude oil. A PTFE hollow fiber MF/UF membrane offers a reliable method of treating this wastewater and provides long duration operation and durability when cleaning the membranes. The PTFE hollow fiber MF/UF membrane is effective in removing oil residues from ot...

PTFE (polytetrafluoroethylene) MF/UF membrane has a unique highly porous three-dimensional fibril structure not seen in other polymeric membranes. PTFE is temperature resistant and exceptionally high chemical resistant. Its temperature resistance allows for treatment of raw water at higher temperature and the chemical resistance allows cleaning by ...
