SWISSResource is Looking for Partners in Switzerland for the Construction of Small Plants for Sewage Sludge Utilization
Container drying with air. Values of 80 to 85% dry matter can be achieved. Feeding from chamber filter press.
CSR Module I for drying sewage sludge: End product: Dry (98%), dust-free, odorless, sterile granulate for further use in waste incineration plants or cement plants or for further treatment in Module II (phosphorus and nitrous oxide extraction)
Chamber filter press for the first stage of pre-drying
Until now, experts were of the opinion that a possible utilization of sewage sludge could only be economically realized in large plants. This mainly concerns dewatering as well as the separation of phosphorus and possibly also nitrous oxide, which will be mandatory in Switzerland and Germany in the future. In particular, the organic fraction of the sewage sludge is to be used for heat or electricity generation.
It is now assumed that such large plants cannot be built cost-neutrally, but that the municipalities must financially burden the population with them.
SWISSResource GmbH is now presenting a concept for decentralized small plants that are cost-effective and generate a profit for the municipalities.
These small plants operate with zero emissions – i.e. without CO2 – and without environmental pollution such as water or chemical consumption. They leave behind clean, largely dust-free and odorless, 100% sterilized and therefore infection-safe granular material. The plants require little floor space, little personnel and maintenance and are cost-effective. An amortization period of around two years can be expected.
The currently designed plants are designed for approx. 20,000 to 50,000 PE.
The specific local parameters must be implemented in each project.
The technology – which can be viewed at www.Curtius-sr.de – is partly based on experience with a plant in Japan (phosphorus and nitrous oxide separation) and a significantly improved drying technology in the steam circuit as well as the introduction of highly efficient pre-drying.
The energy potential can be used via waste incineration plants or cement plants. In a further, expandable expansion stage, the
Expansion stage I:
Pre-drying and drying: Risk very small, as already industrially tested. Offers from SWISSTResource GmbH from 2020.
Expansion stage II:
Phosphorus and nitrous oxide separation: Risk very small, as already industrially tested. Construction in two to five years, as required by law from 2027. Offers 2021.
Expansion stage III:
Production of a CO2-neutral fuel for highly efficient electricity generation by extracting the biological component: still to be developed! Expandable. Construction in 3 to 6 years.
Partner wanted
Partners are being sought in Switzerland for the construction of a plant for 20,000 – 50,000 PE for the realization of expansion stages I and II.
We hope that funding can also be made available for this.
