MR-W5 Mkii Deep Bed Filter Column Demonstration Capabilities Teaching Equipment Hydraulic Bench
• measuring pressure drop profiles through the filter bed • measuring suspension concentration profiles through the filter bed • demonstration of reversed flow fluidisation and backwashing • the column may be readily adapted for absorption and ion • Exchange studies.
TECHNICAL DETAILS • Filter column: Clear acrylic, 100mm internal • diameter x 1350mm long • Typical media depth: 700mm • Gauze mesh size: 0.35mm • Sump tanks: 2 - capacity 350 litres each • Flow meter range: 0.5 - 5.0 litres/min • Manometers: 41 tube multi-bank • Pump rating: 0.37Kw
ORDERING SPECIFICATION • A clear perspex column (100mm internal diameter x 1350mm long) mounted in a floor standing framework approximately 2m high. • Service system comprises of: pump, 2 sump tanks (each 350L capacity), flow controller, rotameter is supported by a corrosion resistant gauze mesh below which is packed 1kg of 10mm Ballotini. • Slotted sample tubes penetrate the filtration medium at various depths. • Sampling and manometer tappings are located at 20mm depth intervals staggered in position over 0.8m column height. • Control valves fitted to the sampling tubes allow isokinetic sampling.
ESSENTIAL EQUIPMENT Filter Media: Approx 10kg of a test medium is required to pack the column. Suitable alternatives include well rounded quartz-grain sand BS16-30 mesh (1.0-0.5mm), anthracite, crushed flint or aluminium oxide.
RECOMMENDED A CCESSORIES • 40 sample collectors (test tubes or bottles) • Turbidimeter or Spectrophotometer • Flexible tubing for drain connection etc. • 1 metre rule • Air foot-pump and pressure tubing (2.5m)
SERVICES REQUIRED Electrical supply: 220-240V/1ph/50Hz OVERALL DIMENSIONS o Height: 2.2m o Width: 2.4m o Depth: 1.0m
