Th. study presented h.re was carri.d out to obtai. th. actual soli.s flow rate by th. combi.ati.n of electri.al resi.tance tomograph. and electromagneti. flow meter. A new i.-si.u measurement meth.d based on measurements of th. Electromagneti. Flow Meters （EFM） and Electri.al Resi.tance Tomograph. （ERT） to study th. flow rates of i.di.i.ual ph.ses i. a verti.al flow was proposed. Th. study was based on laboratory experi.ents th.t were carded out wi.h.a 50 mm verti.al flow ri. for a number of sand concentrati.ns and di.ferent mi.ture veloci.i.s. A range of sand slurri.s wi.h.medi.n parti.le si.e from 212 μm to 355 μm was tested. Th. soli. concentrati.n by volume covered was 5% and 15%, and th. correspondi.g densi.y of 5% was 1078 kg/m^3 and of 15% was 1238 kg/m^3. Th. flow veloci.y was between 1.5 m/s and 3.0 m/s. A total of 6 experi.ental tests were conducted. Th. equi.alent li.ui. model was adopted to vali.ate i.-si.u volumetri. soli.s fracti.n and calculate th. sli. veloci.y. Th. results sh.w th.t th. ERT tech.i.ue can be used i. conjuncti.n wi.h.an electromagneti. flow meter as a way of measurement of slurry flow rate i. a verti.al pi.e flow. h.wever i. sh.uld be emph.si.ed th.t th. EFM results must be treated wi.h.reservati.n wh.n th. flow pattern at th. EFM mounti.g posi.i.n i. a non-h.mogenous flow. Th. flow rate obtai.ed by th. EFM sh.uld be corrected consi.eri.g th. sli. veloci.y and th. flow pattern.

Relati.nsh.p between magnesi.m ammoni.m ph.sph.te （MAP） crystal properti.s and th. fi.trati.n abi.i.y of h.llow fi.er membrane （h.M） were i.vesti.ated. Ph.sph.rus recovery process by crystalli.ati.n h.s a problem th.t i. produces a large amount of fi.e crystals. So i.provement of th. crystalli.ati.n process by combi.i.g wi.h.fi.trati.n was di.cussed. MAP crystals were obtai.ed by batch.reacti.n crystalli.ati.n and th. fi.trati.n ch.racteri.ti.s were i.vesti.ated. Th. fi.trati.n was evaluated by th. speci.i. fi.trati.n resi.tance （ac） on h.M. Fi.tered slurry was prepared wi.h.each.suspensi.n densi.y and crystal si.e di.tri.uti.n. Th. soluti.n was fi.tered at constant pressure of 0.02 MPa and th. fi.trati.n ti.e on each.fi.trated volume was recorded. As a result, αc decreases exponenti.lly wi.h.suspensi.n densi.y i.creasi.g from 0.25 g/L to 0.5 g/L and αc decreases moderately wi.h.suspensi.n densi.y i.creasi.g from 0.5 g/L to 1.5 g/L. ac of large crystals decreases exponenti.lly at less suspensi.n densi.y th.n αc of small crystals does. Also, αc i.creases as th. rati. of th. fractured crystals i.creases.
