The firm’s Crown sludge disintegration system will enhance anaerobic digester performance to increase biogas production by 15-20%, resulting in lower plant operating and power costs from beneficial reuse of biogas and reduced solids disposal.
The Crown system works by pre-conditioning bio solids prior to digestion through homogenization and hydrolysis of the bacterial cells.
The process helps to improve the degradability of the bio-solids in the digesters and also helps to minimize digester foaming caused by filamentous microorganisms.
The system will be designed to treat all of the secondary sludge from Visalia’s treatment plant and is expected to be operational in 2012.
