CE 579 Depth Filtration Didactic Equipment Vocational Training Equipment Fluid Mechanics Lab Equipment
Demonstration of depth filtration and backwashing of filters Features - filtration and backwash - pressure conditions in a filter - software for control and data acquisition Learning objectives/experiments - pressure conditions in a filter - factors influencing the pressure loss (Darcy's law) -- flow rate -- height of the filter bed -- permeability of the filter bed - determine the pressure in the filter bed (Micheau diagram) - backwash of filters -- observe the fluidisation process -- determine the expansion of the filter bed -- determine the required flow velocity (fluidisation velocity) Specification [1] depth filtration and backwash [2] separate supply unit with tank and pump for raw water [3] pump for backwashing the filter [4] 10 tube manometers to measure the pressures [5] plotting of Micheau diagrams [6] electromagnetic flow rate sensor [7] 4 ball valves with motor [8] measurement of flow rate, differential pressure, system pressure and temperature [9] control of flow velocity [10] software with control functions and data acquisition via USB under Windows 10 Technical data Filter - inside diameter: 106mm - total height: 1125mm - max. filter bed height: approx. 700mm Raw water pump - max. flow rate: 150L/min - max. head: 9m Backwash pump - max. flow rate: 40L/min - max. head: 10m Tanks for raw water and treated water - capacity: each 180L Measuring ranges - flow rate: 0...1300L/h - pressure: 1x 0...0,6bar, 10x 0...1260mmWC - differential pressure: -1...1bar - temperature: 0...100°C - filter bed height: 0...720mm 230V, 50Hz, 1 phase 230V, 60Hz, 1 phase, 230V, 60Hz, 3 phases UL/CSA optional LxWxH: 1900x790x1900mm trainer LxWxH: 1200x790x1200mm supply unit Total weight: approx. 370kg
