Effect of activated carbon addition on fouling reduction in membrane filtration processes

다국어 초록 (Multilingual Abstract)

Experiments were conducted by introducing powdered activated carbon (PAC), granular activated carbon (GAC), and anthracite into the membrane filtration system to assess their effects on fouling reduction and improvement of transmembrane pressure (TMP). The results showed that the particle size of the materials added for fouling mitigation was a more significant factor. The total filtration resistance gradually decreased with increasing activated carbon dosage in relation to TMP. When the membrane resistance was excluded, the filtration resistance attributed solely to activated carbon also decreased as the dosage of activated carbon increased. Although the treatment efficiency varied depending on the operation mode(i.e, whether cross flow or dead-end flow) the addition of activated carbon to the membrane filtration process was confirmed to simultaneously suppress fouling and provide adsorption effects.
