Effects of ion concentration and natural organic matter on arsenic(V) removal by nanofiltration under different transmembrane pressures
The removal of As(V) from synthetic water was studied using four different nanofiltration (NF) membranes (ESNA-1-K1, NF270, ESNA-1-LF, and HODRA-CORE). The influences of ion concentration, transmembrane pressure (TMP), and the presence of natural organic matter (humic acid, HA) on the arsenic remova...

| description | The removal of As(V) from synthetic water was studied using four different nanofiltration (NF) membranes (ESNA-1-K1, NF270, ESNA-1-LF, and HODRA-CORE). The influences of ion concentration, transmembrane pressure (TMP), and the presence of natural organic matter (humic acid, HA) on the arsenic removal efficiency and permeate flux were investigated. The arsenic rejection of ESNA-1-LF was higher than those of the other membranes in all experiments (> 94%), and the HODRA-CORE membrane gave the lowest removal of arsenic (< 47%). An increase in the ion concentration in the feed solution and addition of HA decreased the arsenic rejection of the HODRA-CORE membrane. However, both increasing of the ion concentration and addition of HA made the rejection increased for the other membranes (ESNA-1-K1, NF270, and ESNA-1-LF). With increasing TMP, for all four NF membranes, increases in both arsenic rejection and permeate flux were observed. The permeate fluxes of the four NF membranes decreased to some extent after addition of HA to the solutions for operating time of 6 hr. |
