Wastewater Treatment Plant Digesters

 

The energy hidden in wastewater is an untapped resource with the potential to offset 12% of the US electric demand. That’s thousands of POWER PLANTS  ready to be turned on.

 

The country’s aging wastewater treatment infrastructure is facing capital, technical and regulatory challenges. Facilities are progressively required to improve pollutant loading reductions mandated by the Clean Water Act. The US EPA estimates $105.3 bil over the next 20 years for investment needs for aging wastewater treatment infrastructure.

 

Upgrading to high solids digesters is an effective way to address these infrastructure improvements without passing the costs on to ratepayers. Biosolids are pumped into stirred tank reactors, where they can be co-digested with outside organic waste. As anaerobic bacteria break down the volatile solids in the digester, biogas is released and can be combusted to generate electricity. This electricity can be net metered onsite, with the potential for the wastewater treatment plant to become a net-zero facility.

 

Working with quasar

 

quasar’s Project Development Team works with our clients to evaluate their treatment plant’s configuration and develop technology solutions to meet their specific needs.  quasar has collaborated with municipalities and engineering firms to build greenfield plants, retrofit existing assets, complete feasibility studies, and analyze biosolids management plans. With decades of experience our team is prepared to collaborate. Find out more about our design-build services here.
