Sewage Sludge Treatment

Phosphorus recovery from waste biomass is becoming increasingly important, given that phosphorus is an exhaustible non-renewable resource. For the recovery of plant nutrients and production of climate-neutral fuel from wet waste streams, hydrothermal carbonization (HTC) has been suggested as a promising technology. In this study, digested sewage sludge (DSS) was used as waste material for phosphorus and nitrogen recovery. HTC was conducted at 200 °C for 4 h, followed by phosphorus stripping (PS) or leaching (PL) at room temperature. The results showed that for PS and PL around 84% and 71% of phosphorus, as well as 53% and 54% of nitrogen, respectively, could be recovered in the liquid phase (process water and/or extract). Heavy metals were mainly transferred to the hydrochar and only <1 ppm of Cd and 21–43 ppm of Zn were found to be in the liquid phase of the acid treatments. According to the economic feasibility calculation, the HTC-treatment per dry ton DSS with an industrial-scale plant would cost around 608 USD. Between 349–406 kg of sulfuric acid are required per dry ton DSS to achieve a high yield in phosphorus recovery, which causes additional costs of 96–118 USD. Compared to current sewage sludge treatment costs in Switzerland, which range between 669 USD and 1173 USD, HTC can be an economically feasible process for DSS treatment and nutrient recovery.

Sludge Disposal

Thermal treatment is an efficient solution for the sewage sludge disposal, able to deal with the environmental problems related to some harmful elements inside sludge itself, as heavy metals, hormones, pharmaceutical derivates etc. This presentation wants to show the several reliable technologies available today, able to fulfil the requirements for efficiency and cheapness. Other solutions with interesting potentialities are now in a research phase, and they show promising future possibilities of application also from the point of view of the environmental acceptability related to these technologies. In addition to the solutions for the sludge thermal treatment, it will be shown the issue of the phosphorus recovery from sewage sludge, a topical issue that will influence the choices for the sludge disposal in the next years.
