decrease in the conversion time. effective immobilization of the photocatalyst is a major challenge, which will have a
significant effect on photocatalytic reactor design and costs, suppressing additional operations of separating catalysts from
treated water.
However, it is important to take into account that these treatments have to be applied only at small and medium scales.
Combination with other AOPs/ARPs or conventional treatments should also be considered to improve the efficiency of the
removal of contaminants or mixtures of contaminants. Application in real waters should also take into account the presence of
interferences such as phosphates, silicates, and carbonates/bicarbonates, which could influence removal. In this sense, arsenic
removal is very sensitive to these species.
