What term is used to describe particles held in suspension due to the flow of water?

• A. Silt
• B. Settleable solids
• C. Suspended solids
• D. Colloidal particles

Answer: (C)

The term "suspended solids" accurately describes particles that remain in suspension due to the movement of water. This can include a variety of materials such as silt, clay, organic matter, and other fine particles that do not settle to the bottom quickly. Suspended solids are often a crucial consideration in water treatment and environmental science because they can influence the physical and chemical characteristics of the water, impact aquatic life, and affect filtration processes. Their presence can also lead to turbidity, which is the cloudiness or haziness of a fluid caused by large numbers of individual particles. When water flows, these solids are kept in suspension by the turbulence and kinetic energy within the water, which prevents them from settling out. Understanding this concept is vital for operators to ensure effective treatment processes, as well as for calculating detention times and treatment efficiency in various water treatment systems. While terms like silt or colloidal particles refer to specific types of suspended materials, "suspended solids" encompasses a broader range of particulate matter in the water column, making it the most comprehensive and appropriate term for this context.
