Energy Optimization System (EOS)

EOS is an energy efficient technology focused on improving existing municipal wastewater treatment plants by increasing their water flow, loading variation, oxygen supply, nitrogen reduction, energy cost reduction, and CO2 emission reduction. An effective software, in the format of feed-forward oxygen demand control, is utilized in this process, eliminating the dependence on sensors and being reliable and easy to maintain. It is also capable of taking in a large amount of data. A high efficiency hardware, such as the energy saving BKTurbo or high oxygen blower, can be integrated with the software as well.
