Influences on the Process Performance and Design Criteria

Penetration Depth Heat Production Mass and Energy Transport 

Furthermore, water analysis must estabhsh the process-affecting constituents of the water matrix, such as for example, 

The outcome of the water analyses determines the method(s) of pretreatment, for example filtering if the concentration of suspended sohds is too high ([SS] 50 mg L ) or clarification using a clarifier for removal of SS, oil droplets or other suspended materials. 

In all cases proper design tests have to be performed by using a photochemical pilot unit (for an example see Weichgrebe und Vogelpohl, 1995 and Fig. 8-16) that is adapted to the development and variation of the key process parameters affecting the AOP, such as 

During the design experiments, many observations regarding the future engineering concept can be gathered, for example, concerning the formation of inner filters or films on the quartz/water interface.
