Wet air oxidation

Wet or wet air oxidation of sludge is the thermal degradation, hydrolysis and oxidation of organic matter at elevated temperatures and pressures. The process does not generate secondary pollutants such as dioxin, furans, NOx (oxides of nitrogen) and SO2 (sulphur dioxide). It can be operated either to enhance the biodegradability of the sewage sludge or to substantially mineralise the organic matter (i.e. convert it to bicarbonate and carbon dioxide).

Combined hydrothermal carbonization with anaerobic digestion: recycling of the HTC products

Recycling the product streams from a hydrothermal carbonisation process to the anaerobic digester promotes biogas yield in terms of methane volume per unit feed COD, using HTC process conditions of 190 °C and a 1 h reaction time, this research suggests.
