Siemens wins contract at Pearl Valley Cheese

The wastewater treatment system from Siemens will be designed to convert waste material such as methane gas, generated during cheese production, into a reusable biogas. This ‘green’ energy allows Pearl Valley Cheese to receive a state funding grant and reduces the amount of natural gas required to operate the facility’s boilers, which are used for providing steam for the cooking, cleaning and pasteurizing processes.

Siemens will provide an influent screen, neutralization equipment, anaerobic contact process reactor, an Agar moving bed reactor for aerobic polishing and a Dystor Biogas Storage system.

The 50,000-gallon-per-day system is scheduled for start up in the summer of 2010.
