“…Moreover, it has been observed that low pH levels result in a low adherence and fouling propensity of EPS [31]. Nevertheless, further research is needed in order to assess the actual effect of pH on membrane fouling in anaerobic systems.…”

“…Surface modification of membrane using coating or grafting, fouling and biofouling phenomena are most common cases where such layers are encountered [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Adequately assessing the thickness of coatings or deposited layers is of a significant practical interest, yet it is challenging, given the fairly rough and irregular morphology of the underlying membranes and added layers as well.…”

“…pH is an important parameter in biodegradation and membrane fouling too. It has been reported that the rate of membrane fouling is strongly influenced by low pH values thus increasing the adsorption of MBR originated EPS onto the membrane [56]. In this context, many studies approved that the rate of membrane fouling in MBRs increases at lower pH of the mixed liquor [57,58].…”

A novel antifouling coating based on the polymerization of a polymerisable bicontinuous microemulsion (PBM) was developed and applied for commercially available membranes for textile wastewater treatment. PBM coating was produced by polymerizing, on a polyethersulfone (PES) membrane, a bicontinuous microemulsion, realized by finely tuning its properties in terms of chemical composition and polymerization temperature. In particular, the PBM was prepared by using, as the surfactant component, inexpensive and commercially available dodecyltrimethylammonium bromide (DTAB). The coating exhibited a more hydrophilic and a smoother surface in comparison to uncoated PES surface, making the produced PBM membranes more resistant and less prone to be affected by fouling. The anti-fouling potential of PBM membranes was assessed by using humic acid (HA) as a model foulant, evaluating the water permeability decrease as an indicator of the fouling propensity of the membranes. PBM membrane performances in terms of dye rejection, when applied for model textile wastewater treatment, were also evaluated and compared to PES commercial ones. The PBM membranes were finally successfully scaled-up (total membrane area 0.33 m) and applied in a pilot membrane bioreactor (MBR) unit for the treatment of real textile wastewater.
