Lesson 14: Sedimentation And Flotation

Wastewater flow leaves the sedimentation tank over an effluent weir for further treatment. Process efficiency is controlled by detention time (normally about 2 hours), temperature, tank design, and equipment condition. The settling velocity of the particles is the key variable in the design of sedimentation tanks and separator channels.Wastewater flow leaves the sedimentation tank over an effluent weir for further treatment.

Second, open slowly the bottom valve until the water level reach the top of the vertical wall of the tank. Measure the water by volume.Sedimentation Tank Design Parameters. Reading time: 3 minutes. Sedimentation is the process of removing suspended coarser particles in water by settling down them to the bottom of tank. For a particle to settle down, the flow velocity must be reduced. This process is carried out in a structure called sedimentation tank or settling tank.1. For a given discharge, the efficiency of the sedimentation tank can be increased by. 2. The demand of water is 150 litres/head/day in a city of one lakh population. The factor of safety is taken as 1.5, detention time as 4h and overflow rate as 20,000 litres/day/m 2.

NSF certified. 5 year limited warranty. Ship weight 10 lbs.Sedimentation 2 SEDIMENTATION BASIN ZONES . Most sedimentation tanks are divided into these separate zones: Inlet Zone . The inlet or influent zone should distribute flow uniformly across the inlet to the tank. The normal design includes baffles that gently spread the flow across the total inlet of the tank and prevent short circuiting in the tank.The limit for wastewater retention time in preliminary and post-sedimentation tanks is 1 to 1.5 hours and 1.5 to 2 hours respectively. The size of the sedimentation tank is limited by the technical construction of the squeegee mechanism. Effectiveness. A very high removal yield can be achieved if the installation is designed correctly.
