The typical composition of total solids in wastewater consists largely of organic matter, which often accounts for a significant portion of the total solids present. In various studies and practical applications, it is commonly determined that organic matter makes up around 65% of the total solids in wastewater. This percentage reflects the predominance of biodegradable materials, such as organic waste from food processing, human waste, and other biological substances.

Organic matter plays a crucial role in the treatment processes, as its breakdown is essential for effective wastewater treatment, especially in processes such as anaerobic digestion. Understanding the composition of total solids is vital for operators to manage treatment processes effectively, ensure compliance with environmental regulations, and optimize the reuse of byproducts.

While other percentages may seem plausible, they do not represent the commonly established proportions found in wastewater analysis. This context helps in comprehending the importance of organic matter in wastewater management and treatment processes.
