Oily waste water treatment by Ceramic membrane

The waste emulsion problem widely exists in iron& steel work may thoroughly be solved by being treated with ceramic membranes. Ceramic membranes based on aluminum oxide are operationally reliable filter medium –in particular under extreme conditions –with an excellent chemical, thermal and mechanical strength that is matched by almost no other material. Consequently, membranes made by JIUWU COMPANY are primarily used when polymer membranes are no longer able to meet the requirements. Moreover, due to their high separation potential, membrane processes are considered an alternative option than in many cases is superior to conventional process. They take the place of the imported equipment of the same category so as to greatly decrease the treatment cost and bring about large-scale economic and social benefit. The technical& economic index of this ceramic membrane technology has relatively greater advantage than that of the same kind technology abroad. Technical Characteristics of CERAMFIL® process for oily waste water (ceramic membrane) * Oil rejection efficiency is more than 99.9%. * The recoverable oil can be used again. * No demulsifier, flocculant. * Less waste water drained. * Lowest energy cost because optimization of membrane and system design. * Long work life for membrane filter * Membrane layer is more abrasive compared with TiO2 and polymer membranes. * Membranes is easy to be regenerated by normal chemicals like NaOH or HNO3. * Reliable operation with PLC control. * Easy maintenance which will save much labour cost.
