HM 142 Separation In Sedimentation Tanks Didactic Equipment Vocational Training Equipment Fluid Lab Equipment
Solid/liquid separation in a sedimentation tank, visualisation of flow conditions Features - transparent sedimentation tank for observation of the separation process - illumination for optimum visualisation of the flow conditions - possible to use lamellas in the sedimentation tank Learning objectives/experiments - basic principle for the separation of solids from suspensions in a sedimentation tank - determine the hydraulic loading rate - influence of the following parameters on the separation process: -- concentration of solids -- flow rate -- flow velocity in the inlet -- water level in the sedimentation tank - investigation of the flow conditions - how lamellas affect the sedimentation process Specification [1] separation of suspensions by sedimentation in the sedimentation tank [2] transparent sedimentation tank with lighting for visualisation of the flow conditions [3] stirring machine in the inlet area of the sedimentation tank [4] lamella unit can optionally be inserted into the sedimentation tank [5] tank with pump and stirring machine to create and transport a concentrated suspension [6] mixture of the concentrated suspension with fresh water gives the raw water to be studied [7] adjustment of the concentration of solids via valves for fresh water flow rate and suspension flow rate [8] adjustable water level in the sedimentation tank and adjustable flow velocity in the inlet [9] electromagnetic flow rate sensor for raw water [10] Imhoff cones for determining settleable substances of a water sample Technical data Sedimentation tank (experimental section) - LxWxH: 900x110x300mm - max. filling capacity: approx. 25L - material: plexiglass Lamella unit - angle of inclination of lamellas: 60° - number of lamellas: 16 Suspension tank - capacity: approx. 85L - material: stainless steel Pump - max. flow rate: 75L/h Stirring machines (max. speed) - suspension tank: 600min-1 - sedimentation tank: 330min-1 Measuring ranges - flow rate: 30...600L/h 230V, 50Hz, 1 phase 230V, 60Hz, 1 phase; 120V, 60Hz, 1 phase UL/CSA optional LxWxH: 2200x790x1540mm Weight: approx. 220kg
