In this paper, results of an experimental study on separation of oil from actual and synthetic oily wastewaters
with mullite and mullite micro effects of different operating parameters such as pressure (0.5 temperature (15
permeation membranes for treatment of synthetic wastewaters were investigated. In order to determine the best operating conditions, 250 wastewaters using mullite membrane. At the best operating conditions (3 bar pressure, 1.5 m/s cross
velocity and 35 °C temperature), performance of mullite and mullite real and synthetic wastewaters were also compared. The results for treatment of emulsions showed that the mullite ceramic membrane has the highest ceramic membrane with 75% alumina performs high PF 244 L/m
membranes,
–alumina tubular ceramic membranes are presented. Mullite and mullite–aluminafiltration (MF) symmetric membranes were synthesized from kaolin clay and α-alumina powder. The–4 bar), cross flow velocity (0–2 m/s),–55 °C), oil concentration (250–3000 ppm) and salt concentration (0–200 g/L) onflux (PF), fouling resistance (FR), fouling and rejection (R) of mullite and mullite–alumina–3000 ppm condensate gas in water emulsions was employed as synthetic oilyflow–alumina membranes for treatment ofR (93.8%) and the lowest FR (28.97%). Also, the mullite–alumina2 h) and low R (81.3%). Also for all theR for the real wastewater is lower than that for the synthetic wastewaters.–178
