Aurora Ridge Dairy is a 2,000-cow dairy operation located near Aurora in Cayuga County, New York. Construction of the farm’s digester began in the summer of 2008 and came online in August 2009, and was funded in part by a USDA Rural Development grant as well as by NYSERDA. The digester effluent is separated using FAN screw-press separators and post-digested separated solids are used for freestall bedding.

Aurora Ridge wanted a digester that met the following requirements: reduce greenhouse gas and odor emissions; reduce pathogens; produce a reliable source of energy; separate manure solids for bedding.

The digester is a hair-pin, plug-flow design and includes the following features: influent heating; biogas recirculation; separation of post-digested effluent; separation of manure solids.
