Effect of Organic Concentration and Type

No Organic Cone. [mgL- as DOC] Calcium Cone. [mM] Hematite pH [-1 Deposition [% Fe] Organic Rejection [% DOC] Flux Decline f%] Rejection [% Fe] after cycles 1, 2, 3  [Pg.142]

As shown in Table 5.5 (No 1, 2, 3), HA concentration was varied from 5 to 20 mgL DOC, but the increase in concentration had only a marginal effect on colloid rejection. The aggregates were not redispersed due to the addition of organics, which stabilised the particles in the OPS case. The deposition of DOC (results not shown) on the membrane increases with concentration, but colloid deposition is constant at about 90%. Organic rejection decreases with increased concentration. [Pg.142]
