What is the typical range for total suspended solids (TSS) in treated wastewater?

The typical range for total suspended solids (TSS) in treated wastewater is indeed around 10 to 30 mg/L. This range is significant for assessing the quality of treated wastewater before it is released into the environment or reused. TSS is a critical parameter because it represents the concentration of suspended material in water that can have adverse effects on aquatic ecosystems, drinking water treatment, and overall water quality.

Within this range, the concentration of TSS indicates that the majority of solids have been removed during the treatment process, reflecting effective filtration and sedimentation practices typically employed in wastewater treatment facilities. A TSS level within this range suggests that the treatment system is operating efficiently while minimizing organic and inorganic particulate matter in the effluent. By ensuring that TSS remains within acceptable limits, water treatment facilities can safeguard water quality and comply with regulatory discharge requirements.
