The city of Ogdensburg installed a membrane gas holder several years ago for storing biogas, a byproduct of the anaerobic digesters. The purpose of storing the biogas is to maintain a supply that can be used as fuel for the boiler which is used to heat the digester.  Utilizing the biogas as a fuel source for the boiler minimizes and can eliminate the need for utilizing natural gas to power the generator which provides a substantial cost savings. The project combined all necessary processes to maximize efficient use of the anaerobic digester biogas, which maximizes use of this natural resource, therefore maximizing cost savings to the City. Installing the digester gas conditioning system was an important step in the process to produce the highest quantity of usable biogas available, as well as to remove the troublesome particulate including siloxanes from the biogas extending the life of the boiler and substantially minimizing maintenance on the boiler.
