The objective of this paper was to determine and compare the theoretical and experimental settling velocity of sand particles in the water. For the determination of settling velocity sand from wastewater treatment plant was selected. Sand is transported to the wastewater treatment plant by a sewer system with sewage water, especially in locations with a combined sewer system. It is necessary to capture and separate sand in the first step of wastewater purification, which is called primary treatment, otherwise sand can cause problems in the technological line that will have an impact mainly on the economy of operation. For sand capture sedimentation is usually used, principle of sedimentation is based on physical properties of the sand, especially depends on density of the sand. For the experimental measurement of the settling velocity of the sand a laboratory track path had been created. Obtained settling velocities were compared to theoretically calculated settling velocities in accordance with the Stokes Law, Allen’s Law and Newton’s Law.
