What percentage of total solids in wastewater is characterized as dissolved solids?

• A. 30%
• B. 50%
• C. 70%
• D. 90%

Answer: (C)

In wastewater treatment, total solids can be categorized into suspended solids and dissolved solids. The dissolved solids represent an important aspect of total solids because they include all the soluble substances in the water, such as minerals, salts, and organic matter that have passed through a filter. Typically, dissolved solids can account for a significant portion of the total solids present in wastewater, often around 70%. This percentage indicates that the majority of solids are not simply particulate matter that can be easily removed through sedimentation or filtration; rather, they consist of substances that remain in solution, requiring different treatment methods, such as biological processes or chemical treatment, to effectively address their presence. Understanding this composition is crucial for effective wastewater management, as it informs operators about the potential for nutrient loads, the necessary treatment processes, and overall water quality. Consequently, the percentage reflecting the ratio of dissolved solids to total solids being around 70% is consistent with typical data observed in wastewater analysis, reinforcing the importance of recognizing this parameter in the treatment process.
