Log History SOUR MEASUREMENT The measurement, along with LOG History, will be visible when this option is selected: The Specific Oxygen Uptake Rate (SOUR), also known as the oxygen consumption or respiration rate, is defined as the milligram of oxygen consumed per gram of volatile suspended solids (VSS) per hour. This quick measurement 1) The last stored logged data (Not actively logging) or has many advantages: rapid measure of influent organic load and biodegradability, indication of the presence of 2) The last data logged from an active logging lot or...
