Deep Bed Filter Column Model FM 65

Deep Bed Filter Column Model FM 65

Sci-tech Deep Bed Filter Column Model FM 65 is designed to study the characteristics of a filter column.

Item Description

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.

Features
 Designed to demonstrate filtration process.
 Non corrosive acrylic filter column used in the trainer.
