Cambi awarded contract at Bonnybrook WWTP

Cambi awarded contract at Bonnybrook WWTP, Calgary, AB Canada CambiTHP® - Thermal Hydrolysis Process

Oct 13th 2016

We are pleased to announce that The City of Calgary has awarded Cambi a contract for the delivery of two (2) lines of Cambi THP B6-4 reactor systems, including associated ancillaries and services for the treatment of Waste Activated Sludge (WAS) prior to digestion.
The City of Calgary’s Bonnybrook Wastewater Treatment Plant is going through a major makeover; taking place in three phases with a scheduled completion in 2022.  The plant will be able to service an additional equivalent population of 325,000 people which will ultimately provide the plant capacity to treat wastewater for a total equivalent population of 1.366 million people.
As part of the Plant D Expansion at The City of Calgary’s Bonnybrook Wastewater Treatment Plant, increased sludge handling capabilities are required due to the greater mass of waste solids generated by the expanding plant.
Technology evaluation demonstrated that employing THP would bring the most significant advantages for the plant. One of the key advantages was eliminating the need for future digesters when considering expansions in the short or longer term.  Other advantages included reduced sludge viscosity, increased volatile solids reduction (VSr), increased biogas production, increased dewaterability of digested sludge and elimination of digester foaming. Cambi was the successful proponent in the THP equipment pre-qualification for the project.
Cambi is the leading provider of technologies for conversion of biodegradable material to renewable energy, bio-fertilizer resources and biofuel; based on Cambi’s patented thermal hydrolysis process (CambiTHP®).  Cambi also wishes to acknowledge their manufacturer’s rep, Waste ‘n WaterTech Ltd. in Calgary, who was intimately involved in securing the order and finalizing terms and conditions.
