Reduction of Sludge Production in Wastewater Treatment Plants

Webb3 maj 2013 · Conclusion. In this work, hydrothermal carbonization of sewage sludge has been carried out. The waste can be thermally converted into carbonaceous solid product with high yields of 74–81%. The resulting hydrochar had a higher energetic content and better adsorption capability than the starting raw material. WebbWhen specifying media, you must consider the amount and type of aeration (coarse or fine bubble) and/or mixing. Aeration and mixing cause the individual pieces to bump into each other and knock off biomass. The movement of the media also improves oxygen transfer and the diffusion of substrate.
