SUSPENDED SOLIDS (SS)

Solids which are not in true solution and which can be removed by filtration. Such suspended solids usually contribute directly to turbidity. Defined in waste management, these are small particles of solid pollutants that resist separation by conventional methods. Suspended solids (along with Biochemical Oxygen Demand: BOD) is a measurement of water quality and an indicator of treatment plant efficiency. Also see Suspended Particulate Matter.
