Siemens' Crown system to help California water conservation plant improve efficiency and lower costs

Siemens Industry Automation Division's Crown sludge disintegration system is expected to enhance anaerobic digester performance to increase biogas production by 15-20%. This will result in lower plant operating and power costs from beneficial reuse of biogas and reduced solids disposal. The system is expected to become operational in the spring of 2012.

The Crown system from Siemens Water Technologies, a business unit of Siemens Industry Automation Division, works by pre-conditioning biosolids prior to digestion through homogenization and hydrolysis of the bacterial cells. The process helps to improve the degradability of the biosolids in the digesters and also helps to minimize digester foaming caused by filamentous microorganisms. Estimated annual savings from added power production and reduced solids disposal will range from US$150,000 to US$250,000.

The system will be designed to treat all of the secondary sludge from Visalia's 18-MGD (68 MLD) treatment plant and can also be expanded to handle additional future loadings. The system will be skid-mounted and delivered to the site pre-piped and pre-wired, ready for connection to onsite utilities.
