New plant uses biogas and natural gas to power wastewater treatment

2G Energy provides CHP plant with biogas and natural gas mix
A new wastewater treatment plant in the northern suburbs will serve up to 750,000 customers and use a biogas-natural gas hybrid system to generate electricity and heat. The plant is designed and built by a team of engineering and construction firms and features a low-noise enclosure and a special mixing technology package.

The Metro Wastewater Reclamation District's new treatment plant at the northwest corner of 168th Avenue and U.S. 85 is needed to accommodate the rapid growth of the northern suburbs. When the plant goes online, it will be ready to treat and clean 24 million gallons of wastewater per day. But sitting on a 90-acre site, the plant can expand to treat up to 60 million gallons of wastewater per day — or to serve about 750,000 customers across Aurora, Brighton, Thornton, Commerce City and Denver. The engineering group CH2M HILL, with sub-consultants Brown & Caldwell and Garney Construction, Denver, was selected as the design-builder and general contractor. 2G Energy Inc. was selected to supply the CHP plant consisting of the 2G patruus 370 with fully integrated MAN engine, having an Electrical Power capacity of 370 ekW/h or 3,071 MW p.a. and a Thermal Power output of 474 kWh/th.

The package is configured with 2G's sound attenuated enclosure reducing the noise level down to <50 dbA. This system is specifically designed to operate on a mix of Biogas and Natural Gas. This special mixing technology package is also in 2G's scope of supply. The controls and switchgear, including utility interconnection are also included.
