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.

Operator:
Metro Wastewater Reclamation District

The Metro Wastewater Reclamation District has established a new treatment plant at the northwest corner of 168th Avenue and U.S. 85. The purpose of the plant is to accommodate the rapid growth of the northern suburbs. Once it becomes functional, the plant will have the capacity to treat and clean up to 24 million gallons of wastewater per day. The plant is built on a 90-acre site, which can be expanded to treat up to 60 million gallons of wastewater per day, which is enough to serve about 750,000 customers across Aurora, Brighton, Thornton, Commerce City, and Denver.

 

The engineering group CH2M HILL, along with sub-consultants Brown & Caldwell and Garney Construction of Denver, has been chosen as the design-builder and general contractor. 2G Energy Inc. has been selected to provide the CHP plant, which includes the 2G patruus 370 with a fully integrated MAN engine. The electrical power capacity of the plant is 370 ekW/h or 3,071 MW p.a., and it has a thermal power output of 474 kWh/th.

 

The package is configured with 2G's sound attenuated enclosure, which reduces 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 included in the 2G's scope of supply. The controls and switchgear, including utility interconnection, are also included.
