total suspended solids
Total suspended solids (TSS) is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed using a filtration apparatus known as sintered glass crucible. TSS is a water qua ...

This ignition generally takes place in an oven at a temperature of 550 °C
to 600 °C. It represents the amount of
volatile matter present in the solid fraction of the measured solution.

Turbidity
Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of water quality.
