Total Suspended Solids (TSS) are particulate matter suspended in water that can negatively impact water quality if not effectively removed. The correct method for removing TSS from wastewater is filtration. This process involves passing the wastewater through a filter, which captures and retains the solids, allowing cleaner water to pass through. Filtration is particularly effective for smaller particles that may not easily settle out of the water.

Sedimentation, while it can also contribute to the removal of TSS, primarily relies on gravity to settle larger solids to the bottom of a tank. It might not be as effective for smaller suspended particles, which could remain in the water column. Evaporation focuses more on removing water by turning it into vapor, which doesn't directly target TSS removal. Incineration, on the other hand, applies to the combustion of materials rather than a treatment method for liquid waste.
