Wastewater Math and Excel Equations

• Waste sludge varies depending on influent BOD concentrations • If expecting high influent BOD, operators can build up sludge inventory – MCRT • Constant amount of sludge is wasted to maintain a target MCRT • Most common due to it being the easiest to maintain – Constant MLSS • Waste based on changes in activated sludge growth rate

Introduction To Activated Sludge Study Guide

Sludge age is the theoretical length of time a particle of activated sludge stays in the treatment plant, measured in days. In an activated sludge plant, sludge age is the amount (lbs) of mixed liquor suspended solids divided by the suspended solids, or excess cell mass, withdrawn from the system per day (lbs per day of waste activated sludge).

PROBLEM OPERATOR SOLVERS ESSENTIALS

the density of sludge particles in activated sludge is very close to the density of water, water resource recovery facilities that track SSV 5 on process control spreadsheets may notice seasonal trends. As water warms in the summer, the sludge will settle faster; as water cools in the winter and becomes denser, the SSV 5 will increase.
