Membrane Ultrafiltration Of Treated Palm Oil Mill Effluent (Pome), Pui Wah Wong
Membrane Ultrafiltration Of Treated Palm Oil Mill Effluent (Pome), Pui Wah Wong
Student Works (2000-2009)
The common practice for treatment of palm oil effluent (POME) in Malaysia employs a combination of aerobic and an anaerobic treatment. Bearing in mind that the quantity of POME produced is high, reaching 740 000 m3 in May 2001, reuse and recycling of treated POME can be an excellent practice in terms of saving of water resources. As the treated POME is already low in certain parameters required by the Department of Environment (i.e. BOD, total and ammoniacal nitrogen, oil and grease), further treatment will greatly enhance the water quality. The purpose of the advance treatment step is to allow …
The Effects Of Air Sparging On Ultrafiltration Of Whey, Ching Soon Tan
The Effects Of Air Sparging On Ultrafiltration Of Whey, Ching Soon Tan
Student Works (2000-2009)
This work concerns the use of gas-liquid two-phase flow to reduce whey proteins and particle membrane fouling in hollow fibre dialyzer by injecting air directly into the whey feed stream. The effects of air bubbles on the permeate flux of the air sparged ultrafiltration system were studied experimentally. In comparison to single phase flow, over the range of operating conditions studied, the gas-liquid two-phase flow increases the ultrafiltration flux by 15% to 87%. The highest gas injection ratio Fgas/(Fliq +Fgas) was found to be in the range of 0.4 to 0.5. Within this range, the bulk concentration of whey proteins …
