As a result, heterogeneous catalysts for the Fenton reaction have been created and evaluated using materials containing transition metal cations, especially iron ions. [24] The Fenton process dramatically reduces hazardous and resistant chemical molecules while also improving the biodegradability of organic compounds.
Some advantages of the integrated system include the following: (1) In some cases, the anaerobic process can decrease the organic load on aerobic degradation and the creation of aerobic sludge, get rid of the organic materials and suspended solid in wastewater, and cut down on the overall size of the reactors
In most cases, the Fenton process has been studied after thermal regeneration and acidic re-dissolution of iron-containing materials.

Various techniques are applied to achieve the protection, like use of insulation materials, white coating, or surface finishes which reduce the influence from outside, use of heat pipe that conduct heat from hot components to cold ones, use black coating for enhancing radiation inside, and so on.
