Norway: HIAS (an inter-municipal company) has awarded Cambi Solutions AS with a new contract to upgrade the existing thermal hydrolysis process at Hamar wastewater treatment plant (WWTP), in the central-eastern part of Norway.
Cambi will replace one of the pulper systems installed 24 years ago and upgrade the THP to Mark II standards. In addition, the plant will be fitted with a new cooler and new pumps. The total upgrade works will ensure that the facility has enough capacity to treat its increasing dry solids feed. The upgrade works are expected to start in March 2020 with project completion during June.
Cambi has through the years had a comprehensive cooperation with HIAS, both for development of the plant, but also for general research of related technology. Hamar is the first full-scale Cambi thermal hydrolysis project in the world and it was developed together with HIAS. The process was considered highly experimental then and Cambi had worked for several years to bench test, design and model the plant. HIAS was Cambi’s first courageous client willing to trust in this new technology and so production for the first thermal hydrolysis system started on 15th of November 1995. The plant was expanded in 2006 with an additional reactor to improve throughput.
Now, when THP at Hamar is 24 years old, the two existing pulpers are showing signs of wear and thus need refurbishment. Cambi’s Mark II upgrade will ensure the plant is prepared to meet future operational, environmental and economical challenges and remain in operation for many years to come.
Through more than two decades, Cambi has been learning from the operations of installed CambiTHP plants, tremendously improving the thermal hydrolysis process. New plants use our state-of-the-art design and technology, with world class performance. For plants using earlier designs, Cambi has developed and standardized the Mark II upgrade package which can considerably improve plant throughput, reduce energy demand, extend plant lifetime or avoid costly future expansions.
