How is high strength wastewater characterized?

High strength wastewater is typically characterized by elevated concentrations of organic material and solids, which can lead to more significant impacts on treatment systems.

When assessing high strength wastewater, several parameters are considered. One of them is the Total Suspended Solids (TSS), which refers to the solid particles suspended in water. A TSS greater than 250 mg/l indicates a higher concentration of solid material, which can overload treatment systems if not addressed properly.

Another important parameter is Fats, Oils, and Grease (FOG). A level greater than 30 mg/l suggests the presence of substances that can create difficulties in the treatment process, lead to clogs, and cause operational challenges within the wastewater management system.

Therefore, both the elevated TSS and FOG concentrations serve as critical indicators that define high strength wastewater. This is why the correct characterization includes both the TSS and FOG parameters, making the choice that encompasses both these criteria the accurate definition of high strength wastewater.
