• and 6 US$ per m3 of treated effluent depending on plant size, quality of effluent to be treated and required treatment limits. Conclusion The combination of NF with photocatalysis is capable of increasing the efficiency of the dye degradation process. NF possesses the ability to reject organic colour

• addressed the influence of the heat-treatment temperature (i.e., crystallite size) on the photocatalytic activity. Thereby, the influence of the crystallite size and mesostructural organization on the photocatalytic activity was systematically investigated by using dye degradation as a qualitative measure

• that, of all the various oxide films, the KLE derived mesoporous MgTa2O6 film possessed the highest activity in assisting the photodegradation of RhB in water. Interestingly, PIB6000-templated mesoporous MgTa2O6 thin film showed a very similar dye-degradation activity as compared with the KLE-templated
