The treatment of post-processing liquid from the hydrothermal carbonization of sewage sludge

Klaudia Czerwinska et al.

Summary: This study focuses on post-processing methods for water derived from the hydrothermal carbonization process of sewage sludge, including membrane separation and coagulation. The results show that double nanofiltration can significantly reduce various indicators such as Chemical Oxygen Demand, conductivity, nitrate nitrogen, phosphate phosphorus, total organic carbon, total carbon, and inorganic carbon. In the second group, the addition of 10 cm3/L of iron coagulant to the permeate from ultrafiltration achieved the best reduction effect for multiple parameters.

Hydrothermal carbonization of sewage sludge: Hydrochar properties and processing water treatment by distillation and wet oxidation

Malgorzata Wilk et al.

Summary: Hydrothermal carbonization is an innovative method for the disposal of sewage sludge, with the solid product hydrochar having potential uses as fuel or fertilizer. The gaseous products mainly consist of CO2 and nitrogen, while the post-processing liquid, which accounts for about 80%, is highly toxic. This study aimed to investigate the potential of hydrochars derived from sewage sludge as fuel, and to utilize the filtrates after purification. The results showed that hydrochars exhibited improved energy properties and dewaterability compared to raw sewage sludge, with better chemical composition and filtration efficiency.

Hydrothermal Carbonization Process of Digestate from Sewage Sludge: Chemical and Physical Properties of Hydrochar in Terms of Energy Application

Malgorzata Wilk et al.

Summary: Hydrochars derived from sewage sludge digestates were examined for their fuel properties. The hydrothermal carbonization process and the composition of the digestate affected the ash content and combustion characteristics of the hydrochars. The hydrochars from different plants showed similar properties under the same conditions. Distillation treatment of the post-processing liquid phase improved its quality indicators.
