What term refers to a composition of fabric that varies in size depending on the floating and suspended matter?

The term that describes a composition of fabric that varies in size depending on the floating and suspended matter is the mesh screen. A mesh screen consists of a woven or synthetic material with a specific mesh size, which can filter and separate particles based on their size. This adaptability allows the screen to capture varying amounts and sizes of floating and suspended matter in a fluid, making it effective in numerous applications such as wastewater treatment, stormwater management, and even sediment control.

Mesh screens are utilized in various engineering contexts to ensure that unwanted materials are removed from liquids, thus allowing for clearer and cleaner effluent. By using different sizes of mesh, engineers can adapt the screening process to the specific requirements of a project, effectively controlling the flow and quality of materials being filtered.

Other options, while related to water treatment and filtration processes, do not fit the definition as precisely as the mesh screen in terms of the variability based on floating and suspended matter. Grit removal refers to a specific process of removing heavier particles, a barminutor is a device used for screening and grinding, and a vortex chamber serves to separate particles by creating a swirling motion, but none describes a fabric composition that can change based on the sizes of materials.
