摘要

Nondestructive (NDT) and noninvasive ultrasonic techniques have long been used to evaluate the properties and especially the thickness of thin layers. Here, we use this technique adding a new approach to investigate microfiltration of paper mill wastewate

摘要

Membrane fouling control is a major challenge in the fields of membrane technology for water and wastewater treatment. A novel anti-fouling electrocatalytic membrane reactor was designed and proposed for industrial water treatment in this study. A TiO2/carbon membrane used in the reactor was prepared by coating titanium dioxide as an electrocatalyst via sol-gel process on a conductive micro-porous carbon membrane. The TiO2/carbon membrane, namely the electrocatalytic membrane, functions both as a filter and an anode in conditions of electrolysis. During wastewater treatment, the electrocatalytic membrane generated micro-flows to alleviate concentration polarization and reactive intermediates to indirectly decompose the organic foulants on the membrane surface or in pores into CO2 and H2O, or small biodegradable products. The results show that the electrocatalytic membrane reactor exhibited not only excellent anti-fouling ability and self-cleaning function, but also greater removal efficiency towards oily wastewater treatment compared to conventional membrane filtrations. As new equipment and method it would provide wide prospective applications in the fields of various industrial wastewater purifications.

摘要

An ultrasonic time-domain reflectometry (UTDR) technique has been applied to the non-invasive study of fouling in microfiltration (MF) membrane modules operating at 100kPa. The experimental results show a good correspondence between theUTDRsignal response
