The OLR-300 On-Line Respirometer is a true "on-line"
respirometer which gives oxygen uptake rates for
treatment plant operations. Oxygen uptake in aerobic
applications can be measured in batch, sequential-batch,
or continuous modes at rates in excess of 150 mg/l/hr.
When you use the OLR-300 On-Line Respirometer, here's what you get:
- to changes in influent wastewater characteristics
- in the mixed liquor of your activated sludge process
- ...maximizes the diagonistic capabilities of the OLR-300
On-Line Respirometer.
- ...easy set-up, easy cleanup, and user-friendly software
- through modem connections

- The reaction chamber allows you to simultaneously feed aeration tank mixed liquor and your wastewater sample.
- The high-speed mixing lets you measure oxygen uptake rates in excess of 150 mg/l/hr.
- The built-in computer gives you instant monitoring of your data.
- Oxygen uptake rate measurement is relatively independent of temperature variations.
- Oxygen uptake rate measurement is also relatively independent of barometric pressure variation.
- With the OLR you won't have to calculate mass transfer coefficients (KLa).
- You can use a high fill rate (fill the reaction vessel in 2 to 4 minutes) for batch tests.
- You will accomplish a high turnover of mixed liquor in the continuous mode(hydraulic retention times of 15 minutes to 12 hours).
- WindowsTM-based programs are used for system control and data acquisition.
- Continuously measure "on-line" the oxygen uptake of your activated sludge process.
- Determine the impact and treatability of known or possible toxic wastes on your activated sludge process.
- Measure in batch mode the biodegradability of a particular wastewater sample.
- . The OLR-300 system uses mixed liquor from an operating treatment plant to assess the oxygen uptake characteristics when operating under a variety of input conditions.
- . The OLR-300 system can be operated in FOUR modes: 1) mixed liquor only with continuous feed to the reaction vessel to determine instantaneous OUR for control purposes, 2) mixed liquor continuously plus wastewater feed continuously in a wide range of loading rates or food-to-microorganism ratios, 3) batch mode with mixed liquor only to provide batch OUR for diagnostic purposes, and 4) batch mode with mixture of wastewater and mixed liquor for diagnosing biodegradation characteristics of the wastewater.
- . The high rate of turnover of the mixed liquor during OUR monitoring tests provides rapid response to changes in influent conditions.
- . The standard reaction vessel has a 1.5 L working volume.
- . The headspace within the reaction vessel can be operated at almost any oxygen content from air (21%) to 95% to simulate treatment systems using high-purity oxygen processes.
- . (Optional feature)
- . (Optional feature)
- . The operating temperature of the reaction vessel is the same as that in the source mixed liquor basin.
- . User-set oxygen uptake rates can be used to flag high or low OUR conditions in an aeration basin.
- . The OUR-300 system is ideally suited for assessing biodegradation characteristics, including toxicity, of candidate wastewater streams.
