OPTImaster™ is a software program, which provides daily recommendations for
sludge age (SRT), mixed liquor total suspended solids (MLSS) concentration, and
dissolved oxygen (DO) concentration targets or set points. OPTImaster™ selects set
points based on the activated sludge model and past plant performance; these set
points minimize energy usage while maintaining the required effluent quality and
reliability of operation.
Unique Features of OPTImaster™ Software
- Set points are recommended daily.
- Set point selection algorithms are based on the activated sludge model and past
plant history.
- The data mining algorithm combined with the iteration technique provides the
ability to continuously improve plant performance.
OPTImaster™ History
2004: California Energy Commission selects, from a field of 68 applicants, Ekster and
Associates Inc.’s proposal to develop DO and sludge age optimization software.
2005: OPTImaster™ is developed.
2006: OPTImaster™ is installed at the 32 MGD Oxnard wastewater treatment plant and,
used in conjunction with DOmaster™, is documented to provide a 25 percent energy
savings.
