The novel electrochemical membrane reactor for wastewater treatment was designed and introduced. As the key part of the electromembrane reactor, the tubular membrane electrode was prepared and researched. The tubular inorganic ceramic membrane was endowed with electroconductivity by the deposition of pyrolytic carbon from propylene by chemical vapor deposition. The electrocatalytic property of the membrane electrode was realized through dip-coating with chloroplatinic acid solution, drying and hydrogen reduction in order that the electrocatalyst of reduced platinum can be supported. The SEM characterization and water flux test of the membrane electrode show that membrane separation and electrocatalysis can be integrated together.

Adopting an effective strategy to control fouling is a necessary requirement for all membrane processes used in the water/wastewater treatment industry to operate sustainably. The use of ultraviolet (UV) activated photocatalysis has been shown to be effective in mitigating ceramic membrane fouling by natural organic matter. The widely used configuration in which light is directed through the polluted water to the membrane’s active layer suffers from inefficiencies brought about by light absorption by the pollutants and light shielding by the cake layer. To address these limitations, directing light through the substrate, instead of through polluted water, was studied. A UV conducting membrane was prepared by dip coating TiO2 onto a sintered glass substrate. The substrate could successfully conduct UV from a lamp source, unlike a typical alumina substrate. The prepared membrane was applied in the filtration of a humic acid solution as a model compound to study natural organic matter membrane fouling. Directing UV through the substrate showed only a 1 percentage point decline in the effectiveness of the cleaning method over two cleaning events from 72% to 71%, while directing UV over the photocatalytic layer had a 9 percentage point decline from 84% to 75%. Adapting the UV-through-substrate configuration could be more useful in maintaining membrane functionality during humic acid filtration than the current method being used.
