Anaerobic digestion has today become a promising method for sludge treatment and TH is an important pre-treatment method to improve the efficiency of the process, especially for the digestion of WAS.Essentially, under high temperature conditions (130 -200 °C), a hydrolysis reaction occurs to break down complex molecules in sludge into simpler compounds.

This oxidation is following by retention on granular material such as sand. Unlike conventional treatment, which requires addition of a strong oxidant (potassium permanganate, chlorine or ozone) to obtain sufficient oxidation, the Mangaflo™ process developed by Veolia Water Technologies provides manganese treatment with an ecological aspect.
