What does a high level of TSS indicate about treated wastewater?

Low treatment effectiveness
High nutrient levels
Increased BOD
High temperature

The correct answer is: Low treatment effectiveness

A high level of Total Suspended Solids (TSS) in treated wastewater indicates low treatment effectiveness. TSS measures the amount of solid materials suspended in water, which can include organic matter, sediments, and microorganisms. When TSS levels are elevated in treated effluent, it implies that the treatment process was not effective in removing these solids from the wastewater. Effective wastewater treatment processes, such as sedimentation and filtration, are designed to significantly reduce TSS to ensure that the effluent meets environmental standards for discharge. High TSS can lead to water quality issues in receiving waters, as it may cause turbidity, reduce light penetration, and impact aquatic life. Therefore, elevated TSS levels are a signal that the treatment process may require attention or improvement to enhance the removal of solids effectively.
