Waterboard Vechtstromen chooses the Cambi-solution for Hengelo’s sludge center

Cambi will construct a new Thermal Hydrolysis Process (THP) plant in the city of Hengelo, the Netherlands. The Cambi THP sludge pre-treatment will approximately double the capacity of the existing egg-shaped digesters from 9,000 to 18,000 ton sludge per year.

The doubling of capacity allows Waterboard Vechtstromen to shut down the aged digestion facility of Enschede and avoids a costly rebuild of that plant. Cambi pre-treatment of the biological sludge at Hengelo increases the digestion capacity and the biogas production and reduces the final amount of dewatered biosolids. The plant will generate approximately two megawatt of renewable electricity. Cambi’s CEO Per Lillebø congratulated Waterboard Vechtstromen for choosing the Cambi Process that will strongly reduce their operating costs and carbon foot print.

“Cambi will supply the standardized and efficient modular B6 THP product which is a proven solution that has good operating records in Lindum Norway and is being installed in many new and existing plants, including Athens WWTP Psyttalia, Greece,” said Lillebø.

Cambi will also supply coolers and boilers to the Hengelo project. The project is executed in a partnership with the Dutch contractor Logisticon Water Treatment b.v. Logisticon will supply pre-treatment, as well as electrical and civil works and will be responsible for the project management and project coordination.
