Finding MLVSS & MLSS and Adjusting the F/M Ratio in an Activated Sludge Wastewater Plant

Welcome! I’m a California Grade 4 Wastewater Treatment Plant Operator and Chief Plant Operator. I also hold a CA D3 Drinking Water Distribution Operator Certificate and a CA T2 Drinking Water Treatment Plant Operator Certificate. In this tutorial, we cover the reverse Food to Microorganism (F/M) ratio. You’ll learn how to calculate lbs of MLVSS and mg/L MLSS in aeration when given a BOD concentration and target F/M ratio. I also explain how to adjust the F/M ratio if it’s outside your target parameter. This video is perfect for all wastewater operator grades and exam levels, especially Grade III, IV, V, and Class A & B test takers.
