Class C Wastewater Treatment Plant - TREEO Center

Solids are washing out of the secondary clarifier of the activated sludge plant. Plant personnel increase the return activated sludge (RAS) flow rate, which slows the problem temporarily, but gets worse after 30 minutes. What is the cause of the plant problem? increasing the RAS increased the detention time in the clarifier

Lesson10: Sludge Digestion and Solids Handling

The Solids Loading Rate (SLR) is the relationship between the solids entering the clarifier and the surface area of the clarifier. SLR is calculated by taking the suspended solids entering the clarifier (pounds) divided by the surface area of a clarifier (ft²) and is expressed in pounds per day per square feet (lbs/d/ft²).
