Lesson Seven: Feed Rate Terminology

A feed rate is the rate at which a liquid volume or a gram weight of treatment chemical is injected into the water being treated during the course of a specific timeframe, which is usually one minute. When feed rates are expressed in terms of liquid volume, the rate of injection is generally written in milliliters-per-minute (ml/min). When feed rates are expressed in terms of gram weight, the rate of injection is generally written in grams-per-minute (g/min) or in milligrams-per-minute (mg/min).
