What is TSS (Total Suspended Solids)?

Total suspended solids, often abbreviated as TSS, is the combination of the particles that are suspended in the water. It is a common water measurement that is performed to determine the amount of small particulate matter suspended in a water sample. TSS tests are conducted to measure the organic material and dirt that is present in a water sample.

Why is TSS Important?

TSS is an important measure of the water quality, as it indicates both the concentration and nature of the suspended particles. When the amount of suspended particles is excessive in water, it can reduce the clarity of the water and make it unattractive. It can also affect the taste, colour and feel of the water. High levels of suspended solids can also interfere with treatment processes when water is being processed for use.

Testing for TSS

There are a variety of methods that can be used to test for total suspended solids. One of the most popular methods is to measure the particles that are retained on filter paper, with solid residue remaining on the filter paper being considered as TSS. It is a relatively simple process, although it can be time-consuming and expensive. Other tests include using a turbidity tube, direct laboratory analysis, or using a spectrophotometer. Whichever method is used, it is important to ensure accurate measurements – and to ensure that the right type of test is chosen for the intended purpose.
