A fixed volume of sample is filtered through a preweighed and washed glass fiber filter. The filter is then rinsed and dried at 103 to 105 C. The change in the weight of the filter represents the weight of suspended material. This test is typically done for surfacewater supplies and wastewater treatment plants. For drinking water, turbidity is parameter that is typically monitored.
The total amount of suspended solids dispersed in a liquid.
The portion of the sediment load suspended in the water column. The grain size of suspended sediment is usually less than one millimeter in diameter (clays and silts). High TSS concentrations can adversely affect primary food production and fish feeding efficiency. Extremely high TSS concentrations can impair other biological functions such as respiration and reproduction.
