“…Since TMP becomes higher, the driving force for oil diffusion into the permeate side also increases. When there is no compaction of membrane at lower pressure range, permeate flux is controlled by pressure (Lin et al, 1997). The result obtained in this experiment indicates that within the TMP range (1-2 bars), there is no membrane compaction observed.…”

“…Phospholipids content of crude soybean oil was reduced from 21540 mg/kg to 2580-3750 mg/kg with membrane degumming and percentage of phospholipids rejection was calculated as 82.59-88.02% (Table 2). The molecular weight cut-off value for membranes, which is defined as the smallest molecular weight species for which the membrane has more than %90 rejections, plays a critical role in the maximum retention of phospholipids and permeate flux (Lin et al, 1997).…”

The objective of this study was to investigate the performance of PVDF membrane in degumming of undiluted crude soybean oil by using reverse osmosis/ultrafiltration module. The effects of membrane degumming conditions including temperature, membrane pressure, feed velocity, and volumetric concentration factor on permeate flux and phospholipids rejection were evaluated statistically. The effect of membrane pressure and volumetric concentration factor on the permeate flux was found to be statistically significant (P <0.05). An 86.11% rejection of phospholipids and average permeate flux of 17.04 L/m 2 .h in total process were achieved at 40°C, 20 bar pressure, and 9L/min feed velocity. As the feed velocity increased to 18 L/min, phospholipids rejection and average permeate flux in total process were determined as 82.81% and 27.51 L/m 2 .h, respectively. The flux behavior of PVDF membrane was also studied. Behavior of permeate flux with process time showed two separate regions namely; falling permeate flux region and constant permeate flux region. A second degree polynomial relationship was observed during falling permeate flux region; whereas a linear dependency was set for constant permeate flux region. A logarithmic equation was obtained when total process behavior was examined.Keywords: Soybean oil, phospholipids, PVDF membrane, ultrafiltration MEMBRAN DEGUMMING KOŞULLARININ PERMEAT AKISI VE FOSFOLİPİTLERİN REDDEDİLMESİ ÜZERİNDEKİ ETKİSİ ÖzBu çal›flman›n amac›; ters osmos/ ultrafiltrasyon modülü kullan›larak soya ya¤›na uygulanan degumming iflleminde polivinilden fulorid (PVDF) membran›n performans›n›n araflt›r›lmas›d›r.

“…Since 21st century, the ceramic membrane has been widely used in the oily wastewater, emulsion wastewater treatment, printing and dyeing, papermaking wastewater treatment, brine refining and so on. Sang H Hyun [1]used the self-made composite membrane to separate the emulsion, and the removal rate could reach 100%.Lin [2]used the polymer membrane to treat the wastewater containing vegetable oil, when the operating pressure was 2.1MPA,operating temperature is 313K,membrane surface velocity is 220L/h,the membrane flux is about 26.8 L/ m 2 ·h .Thus, membrane filtration turns out to be a trend in the future.…”

: The composition and complexity of oily wastewater contains many solid particles, free oil, emulsified oil and so on.It brought about a series of environmental pollution problems when oily wastewater was directly discharged into rivers, lakes and other water bodies. Therefore, researchers are committed to study how to deal with oily wastewater to deal with oily wastewater to apply it to meet the requirements of water injection.Inorganic porous ceramic membrane has excellent properties among many filtering methods. For example, high temperature and high pressure resistance, resistance to acid and alkali, low energy consumption, no pollution to the environment and has a good prospect in the field of oily wastewater treatment, which has attracted the attention of many scholars not only at home but also on abroad. This article describes the present situation of the research on the treatment of oily wastewater by ceramic membrane in recent years, and expounded the significance of the treatment of oily wastewater to people's lives and makes an expectation for the development of inorganic porous ceramic membrane in the future.
