摘要

Fouling is readily acknowledged as one of the most critical problems limiting the wider application of membranes in liquid separation processes. A better understanding of fouling layer formation and its monitoring is needed in order to improve on existing

摘要

An ultrasonic technique was successfully applied to remove fouling and recover the permeate flux of flat sheet microfiltration (MF) membranes. Three kinds of cleaning methods were used, namely: forwardflushing, ultrasonic cleaning and ultrasound with forw

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

摘要

liquid separation processes is of great importance to the development of strategies to improve operating conditions. In this study ultrasonic time-domain reflectometry (UTDR) was used to measure organic fouling, in real time, during ultrafiltration (UF) w

摘要

Many models of foulant deposition on a membrane surface during reverse osmosis (RO) are based on fluxdecline data and scanning electron microscopy (SEM) to predict the mechanism of fouling. The actual mechanism of calcium sulfate deposition remains incomp
