Reagent dosing

Chemical conditioning through reagent dosing is designed to coalesce (or agglomerate) the smaller sludge particles (1−10 µm) to produce larger ones, and to reduce the colloidal (the sub-0.1 µm particle/macromolecular size range) content of the particulate matter. This then increases both the particle sedimentation rate and the permeability of the cake − the solids sediment formed from the particles. In doing so, the efficiency of the downstream thickening and dewatering processes is increased.

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.
