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

• A. 30%
• B. 50%
• C. 70%
• D. 90%

Answer: (A)

The correct answer indicates that approximately 30% of the total solids in wastewater are characterized as suspended solids. This classification is important in wastewater treatment because suspended solids consist of solid particles that are not dissolved in the liquid, which can pose various challenges in the treatment process. These solids can include organic debris, silt, and other particulate matter that can lead to problems such as increased turbidity and potential blockages in treatment systems. Understanding the composition of wastewater is crucial for the design and operation of wastewater treatment facilities, as it directly impacts processes like sedimentation and filtration. By recognizing that around 30% of the solids are suspended, operators can better prepare for the necessary treatment steps to effectively remove these solids and ensure compliance with environmental regulations. This percentage helps in setting design parameters for equipment and determining the required treatment levels to achieve optimal results in the treatment process.
