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 m²) and applied in a pilot membrane bioreactor (MBR) unit for the treatment of real textile wastewater.

开发了一种基于可聚合双连续微乳液（PBM）聚合的新型防污涂料，并将其应用于可商购的用于纺织废水处理的膜。PBM涂层是通过在聚醚砜（PES）膜上聚合双连续微乳液来生产的，该乳液是通过微调其化学组成和聚合温度来实现的。特别地，通过使用便宜且可商购的十二烷基三甲基溴化铵（DTAB）作为表面活性剂组分来制备PBM。与未涂覆的PES表面相比，该涂层表现出更亲水的表面和更光滑的表面，使得所生产的PBM膜具有更高的抵抗力并且更不容易受结垢的影响。通过使用腐殖酸（HA）作为模型污垢剂评估PBM膜的防污潜力，并评估透水性的降低作为膜结垢倾向的指标。当将PBM膜应用于染料废水处理模型时，还评估了其在染料去除方面的性能，并将其与PES商业膜进行了比较。PBM膜最终成功按比例放大（膜总面积0.33 m²）并应用于中试膜生物反应器（MBR）单元中，以处理实际的纺织废水。
