Sci-tech Deep Bed Filter Column Model FM 65 is designed to study the characteristics of a filter column.
It consists of an acrylic unit with flanged end pieces to allow easy access. It consists of a column filled with Ballotini packing to ensure the good water distribution.Slotted pressure tapings are mounted on the column for measuring the pressure drop across the bed pe r unit length and staggered over an approximate 0.8 m depth. These tapings are connected to a differential manometer. These tapings can also be used for drawing the samples from the column and change in concentration of the suspension can be determined. The unit is complete with 2 Nos. of feed tanks. A centrifugal pump is provided to circulate the water through the column under 1 Atmospheric pressure. Water supplied to the column is regulated and controlled by Rotameter. The 10 kg bag of filter medium will be supplied with the set-up. Detailed Operation & Maintenance Manual is provided along with the trainer.
Designed to demonstrate filtration process.
Non corrosive acrylic filter column used in the trainer.
The unit comprises the following main items:
Filter column: Clear acrylic, 100mm internal diameter x 1350mm long
Typical media depth: 700mm
Gauze mesh size: 0.35mm
Sump tanks: 2 – capacity 250 to 350 litres each
Flow meter range: 0.5 – 5.0 litres/min
Manometers: 21 tube to 41 tube multi-bank
Pump rating: 0.37Kw
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.
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)
Measuring how fast total head loss increases with filtration run
Measuring pressure drop profiles through the filter bed
Measuring suspension concentration profiles through the filter bed
Demonstration of reversed flow fluidization and backwashing
The column may be readily adapted for absorption and ion Exchange studies.
– Mains power supply: 220-240V, 1Ph, 50Hz
