What causes instability in solid-contact units?

Instability in solid-contact units, often utilized in water treatment processes such as clarification, can be significantly impacted by temperature fluctuations. This is because variations in temperature can affect the density and viscosity of the water being treated, which in turn influences the performance of the solid-contact process. Temperature changes might cause the solid particles to either rise or settle unevenly, disrupting the intended separation of solids from liquids. Additionally, temperature can affect the kinetics of any biological or chemical reactions occurring in the unit, potentially leading to suboptimal performance or even failure.

It's important to maintain stable operating conditions in solid-contact units, and temperature is a vital parameter. By keeping temperature variations minimal, operators can ensure consistent performance, effective separation, and optimal treatment outcomes.
