| Abstract: | The objective of the paper is to investigate the suitable conditions for backflushing in the cross-flow microfiltration process to separate CaCO_3 particles from the suspension in the inorganic ceramic membrane coupling reactor.The effect of the backflushing conditions on the flux and the effect of backflushing on the microfiltration process are studied.The obtained optimization conditions are as follows: backflushing pressure 0.6 MPa,backflushing time 3 s and the backflushing interval 10 min.The repeatability of the backflushing process is also examined. |
