Deep Bed Filter Column
The deep bed filter is a demonstration unit for treatment of water with suspended particles by sand filtration.
The unit consists of a filtration column is fitted with vertical row of pressure tapping points on one side and similar sampling points on the other side. Both ends of the column are closed with flanges for liquid inlet and outlet. A pump delivers raw water from the raw water tank to the top of the column. Suspended particles are trapped in the sand filter as water flow down through the column to the bottom via filter. The treated water is collected from the bottom in a treated water tank. Hoses connect pressure from the tappings along the side of the column to a manometer bank. Samples of raw water is collected from the sampling points on the side of the column. A manometer bank is provided for measurement of pressure along the column.
Overtime more particles are deposited in the filter which increases the pressure drop across the filter and flow rate decreases. Backwashing is required using treated or clean water and pressure drop is reduced again. Required pipings are provided. The filter unit is on a steel frame.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Understanding the principles of depth filtration by sand filter.
- Measurement of filter differential pressure vs flow rate.
- Observation of pressure drop with time.
- Measurement of suspended particles at different height.
- Demonstration of back washing.

Chemical Engineering EquipmentFixed and Fluidized Bed Apparatus
This bench top apparatus is designed for a study of fluid bubbling phenomena in fixed and fluidized beds of solid particles.
The apparatus consists of a water and an air system. Each has a fluidized column and a pump. Air or water is supplied to the column via bottom porous plate and escape to the top. Control valve varies the rate of flow. Two sizes of bed materials are supplied.
Measurement of flow rate is by rotameter and pressure drop is by manometer.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Visualization of fluidization.
- Pressure drop through packed and fluidized beds for both water and air systems
- Observation of difference between particulate and aggregative fluidization Verification of Carman – Kozeny equation.
