Characterization of Sustainable Flux Of Flocculated Mixtures. Cross-flow micro-filtration experiment set-up, страница 3

After 30 minutes filtration, the flux was close to the steady state. At this point in time, the results showed that all the five parameters (pH, TMP, CFV, T and I), together with TMP*CFV interaction effect significantly affected flux (shown in Fig.4). However, temperature and ionic strength effects still dominated the value of the flux.

4.  Conclusions

It can be concluded that temperature is a very important parameter to control during filtration of particulate mixtures. It has a major effect on filtration flux at all stages of the experiments. However, as the filtration progresses from start-up through to steady state operation, other factors, such as ionic strength, begin to have an impact on performance. By the time steady state operation is achieved, all parameters investigated were making a significant contribution to the operating flux.
