Water which generally has a blurred appearance and accumulates sediment at the bottom is considered as sedimentary. The sediment in water is a very unacceptable factor, regardless of how water is used. In general, the color of the water is mixed with the residue. However, the color of the water generally indicates the presence of dissolved organic substances or heavy metals in the water. These are not sediments.

It is possible to remove the sediment in the water in a variety of ways. For this purpose, automatic backwash sediment filters, or cartridge filters or sand and anthracite filters are used. Cartridge and steel filters are preferred because they are small in size and cost-effective, but these devices only serve as filtration and require frequent cleaning and regular maintenance.

Sand and anthracite filters are mostly used in laboratories. In these devices, filtration is not only effected by filtration but also by suction. These devices are much more effective and safe. In this system, however, the filtration rate of the tank should not exceed 15 cubic meters per hour. If this limit is exceeded, the suction effect of the device is eliminated and pressure loss is experienced.

Sediment determination processes carried out in the authorized laboratories within the scope of physical analyzes play an important role in determining the quality of drinking and domestic water. Laboratories are based on the standards published by local and foreign organizations in these studies. The standard considered in this respect is:

• TS EN ISO 5667-15 Water quality - Sampling - Part 15: Guide for the protection and transport of sludge and sediment samples

This standard is an important guideline for the protection and treatment of sewage water, sludge accumulated in water installations, suspended substances and freshwater and salt water sediments.
