Pulsed-Flow respirometers provide information needed to help you optimize treatment plant performance through measurement of oxygen uptake for aerobic biological reactions and gas production from anaerobic and anoxic biological reactions.  Measurement capabilities include 1) biodegradation rates; 2) biomass activity; 3) oxygen uptake rate fingerprints; 4) extant kinetic measurements; 5) toxicity assessments; and 6) diagnosis of nutrient or trace mineral deficiencies.   Overall, respirometric measurements help to optimize process performance and improve process stability.
