ZM8110 Deep Bed Filter Column Demonstration Capabilities Fluids Engineering Training Equipment Educational Equipment Vocational Training Equipment 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 fluidisation and backwashing
• the column may be readily adapted for absorption and ion
• Exchange studies.
