26842 Biogas reactor

Søndre Follo Treatment Plant IKS intends to expand the current test facility with 1 Antec 105 m3 plug reactor, to a total of 4 plug reactors with the aim of phasing out the current rotten tanks, i.e. procure a further 3 reactors of 105 m3 for pasteurisation and removal of the treatment plant ́s sludge. The procurement is for 3 complete reactors with instrumentation, as well as a number of consultant hours. SFR will carry out all of the technical building works and all integration with SFR ́s existing installations. SFR has carried out a study for a new sludge treatment facility consisting of 4 plug reactors of 105 m3. The study shows that Antec's technology safeguards SFR's need for pasteurising and digesting the sewage sludge. The study shows that Antec's technology is the technology that covers the municipality ́s need for a future-oriented, reliable and environmentally efficient sludge system. The choice of Antec technology is justified by documented advantages connected to waiting times, energy consumption, climate and environmental footprint, area requirements and operational costs as well as not least two years experience in the operation of test reactor. SFR has particularly emphasised that the plant shall have high operational security and low technological risk, and that the system must be suitable for municipal sewage sludge under conditions comparable with Norwegian conditions, including cold and hot seasons. Based on the study, SFR's need assessment and overall …
