Intensive and extensive studies on photocatalysts over the past 20 years have demonstrated their applicability to water treatment and their limitations. A single application of a photocatalyst is not possible for all types of waste water. It can be used as secondary and tertiary treatment. An other possible way is to combine it with hydrogen peroxide, ozone or others materials. Development of other applications besides waste water treatment is also under way. 

For problematic waste waters, secondary biological treatment is insufficient to meet the increasingly strict legislative standards on COD, colour and priority pollutants such as pesticide and herbicide residues. Whilst pollution prevention will always be the environmentally preferable option, this is not always practical, and in such cases tertiary treatment with catalysed hydrogen peroxide can present an economical and effective way to achieve compliance.

According to the size of solids originally present in sewage, current processes for the treatment of waste-water may be divided into the following main categories of pretreatment, primary treatment, secondary treatment, and tertiary treatment.

Tertiary treatment. Tertiary or polishing treatment prepares the aqueous waste for final discharge. The final quality of the effluent depends on the nature and flow of the receiving water. Table 11.3 gives an indication of the final quality required. ...
