This slide presentation outlines a study on the effect of pH and natural organic matter (NOM) on the removal of microcystin-LR by a powdered activated carbon-ultrafiltration (PAC-UF) system. Objectives of the study include: investigate the application of PAC-UF system
for the removal of microcystin-LR;
examine the effect of natural organic matter
(NOM) on the removal of microcystin-LR by
PAC adsorption, UF, and PAC-UF system; and,
examine the effect of pH on the removal of
microcystin-LR by three processes. Results outlined for the first objective include: process variables for the best process configuration;
PAC process and type;
UF (Ultrafiltration) process;
membrane characteristics (Hydrophobicity, Pore size); and,
hybrid PAC-UF system,
membrane characteristics and
PAC dosage. Results outlined of the second objective include: PAC process,
the effect of NOM on PAC adsorption capacity for microcystin;
UF (Ultrafiltration) process,
the effect of NOM on the removal of microcystin by UF
membranes - simultaneous and sequential addition of NOM and
the effect of NOM-fouled membrane on rejection of microcystin; and, hybrid PAC-UF system and
the effect of NOM on microcystin removal by PAC-UF. The third objective for future study includes: investigation of the
effect of solution pH on
the removal of
microcystin-LR by three
processes; and, PAC adsorption - the
adsorption of microcystin
on PAC decreased with
increasing pH. Includes tables, figures.
