Abstract

Oily waste water has been generated from food, automotive, metal processing industries as well as petroleum exploration and refinery. Polyethersulfone ultrafiltration membrane was investigated for treatment of oil in water emulsion. The emulsion models were made based on industrial oily wastewater characteristic in the oil refinery. Flux and rejection were evaluated in order study the fouling and rejection behaviour. Results showed that more than 90% of COD and 85% surfactant were rejected. The permeate flux decline was analyzed in order to study the membrane fouling. In addition, the Hermia model is adopted to investigate the fouling mechanism during ultrafiltration of oil in water emulsion. Analyze of blocking mechanism using Hermia’s model reveal that ultrafiltration of both diesel and mineral oil have good agreement with complete blocking mechanism.
