Sequential Batch Reactors (SBR)

Waste Every Day!

• Wasting proactively will maintain control of the biomass and stabilize the Food to Mass ratio

• Wasting reactively could result in over population of the biomass, reduced DO, odors and solids loss

Closely Monitor SCADA

• Know the sequential reaction times and cycles

Know Your Data

• Know flow trends, mixed liquor and effluent TSS and BOD data and trends through the week

and month

• Know the dissolved oxygen DO concentration in the mixed liquor during the react, or aeration

phase

Take Care of Your Plant

SBR’s depend on working valve actuators, level sensors and flow meters operated by programmable logic

controllers (PLC’s) and sophisticated SCADA monitoring. Care of the equipment, sensors and probes is critical

for effective SBR operation. Good housekeeping contributes to reliable operation.
