Anaerobic digestion (pre-treatment)

Focus on the first step (hydrolysis).
Then the important parameters to control in the hydrolysis step (pH, nutrients, etc).
Talk about the ways to improve the hydrolysis step, focusing on the pre-treatments of sludge.
Explain the different types of sludge pre-treatments. Talk in more detail about thermal pre-treatment
and the use of advanced oxidation processes (AOPs) as pre-treatments of sludge (related to wastewater treatment plant). In the AOPs talk a little about Fenton process and the use of oxidants
(advantages and disadvantages).
In the end, a piece of small information about the use of the final sludge as a fertilizer in agriculture.
