March 2013 Emerging Technologies Technology Summary State of Development: Emerging. Aeration prepared 2012 Critical Oxygen Point Control Objective: Improve aeration efficiency by controlling the optimum delivery of oxygen in the aeration basins. This is done by determining the critical oxygen point of the wastewater under aeration and utilizing this data to change the DO setpoint. Description: Critical oxygen point control is a control method based on respirometric measurements. Bacteria respire by diffusion of oxygen across their cell wall. Oxygen diffuses from a high concentration external to the bacterial cell wall to the low concentration internal to the bacterial cell. Diffusion will only take place once the oxygen concentration differential across the cell wall is sufficient to drive the oxygen through it. The minimum concentration at which this occurs is called the critical oxygen point. Below the critical oxygen point, the biodegradation rate will rapidly decrease. At the critical oxygen point, the biodegradation rate will be at a maximum for the available food source (i.e., organic compounds and ammonia in the wastewater being treated). Accurately knowing the critical oxygen point for the active biomass allows the optimal DO setpoint to be determined. Strathkelvin Instruments (Scotland, UK) has developed a proprietary software upgrade to their Strathtox line of respirometers that, in real time, determines the critical oxygen point of the wastewater under aeration and utilizes this data to change the DO setpoint to control the optimum delivery of oxygen in the aeration basins. Comparison to Established Technologies: The vendor claims substantial savings in reducing aeration cycles while increasing utilization of available capacity and reducing energy costs. Available Cost Information: Not available.
