What is NOT a component of total solids?

Total solids in wastewater consist of various components that contribute to the overall mass of solid material present. Fixed solids, volatile solids, and suspended solids are all integral parts of this measurement.

Fixed solids refer to the non-volatile portion that remains after wastewater is subjected to high temperatures. These solids primarily comprise inorganic materials and thus contribute to the total solids count.

Volatile solids are those that can be vaporized or decomposed at elevated temperatures, typically organic matter that can biodegrade. They play a crucial role in the treatment process as they are often considered the biodegradable fraction of total solids.

Suspended solids are particles that are not dissolved in the water and can include both organic and inorganic materials. They affect water quality and are a significant parameter in wastewater treatment.

On the other hand, heat-treated solids are not typically recognized as a standard component of total solids. Instead, they may be a result of processing but do not represent a specific category within the conventional classification of total solids in wastewater analysis. Therefore, identifying heat-treated solids as not being a component of total solids is accurate.
