چکیده
|
In the present study, fouling was studied in microalgal membrane bioreactor under mixotrophic conditions in different nitrogen sources# n-rich wastewater, containing ammonium and nitrate source, was used as a nutrient source for cultivation of microalgae# the transmembrane pressure (tmp) jumping was seen in both nitrogen sources, while the tmp jumping in ammonium source was observed earlier than one in nitrate source# the results confirmed that the membrane fouling rates increased in ammonium source through increased production of carbohydrates in soluble microbial product (smpc)# it should be considered that both extracellular polymeric substances (eps) and microbial soluble products (smp) are important parameters for membrane fouling in microalgal membrane bioreactor#
