Lime and solids dosing

Solids with appropriate properties can be used to supplement lime dosing for sludge stabilisation, reducing the lime dose required. This can be a favourable option if the solids are low in cost (i.e. waste materials such as fly ash generated from coal combustion) and offer a similar alkaline stabilisation propensity as lime.

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.
