What type of solids includes materials that can be suspended or dissolved in wastewater?

Organic Solids
Inorganic Solids
Settable Solids
Volatile Solids

The correct answer is: Inorganic Solids

The correct choice refers to a category of solids that encompasses substances that can either be suspended in the water or dissolved within it. Inorganic solids are typically non-carbon-based materials; they include elements and compounds such as salts and minerals that can be present in wastewater. The characteristic of being suspended or dissolved is crucial for understanding how these solids behave in treatment processes. Organic solids, on the other hand, are primarily carbon-based materials and generally do not include inorganic compounds. Settable solids refer to particles that settle out of suspension under the influence of gravity, which doesn't pertain to the dissolved state. Volatile solids are a subset of organic solids that can be lost through evaporation when heated, suggesting that they are also not representative of all materials that can be dissolved. In summary, inorganic solids are defined by their presence either in a suspended phase or dissolved in the wastewater, making them the appropriate classification for this question.
