3. 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.
