Basic General Wastewater Study Guide
MGD is a common wastewater flow measurement in a treatment plant, expressed as millions of gallons (MG) of wastewater flowing each day. pH is a measure of the acidity or alkalinity of a sample on a scale of 0 to 14 (acidic to alkaline). A pH of 7 is neutral. Septage is the high strength waste pumped out of septic tanks, sometimes disposed at

Flow balancing, also called flow equalisation, is used to overcome the operational problems caused by flow rate variations and to improve the performance of the downstream unit processes. In other words, flow balancing is simply the damping of flow rate variations so that a constant or nearly constant flow rate can be achieved.
