Liquid Sedimentation Test System
The Liquid Sedimentation Test System by Atto Labware is a bench-mounted educational apparatus designed to study the settling behavior of suspended solid particles in a liquid. The unit features multiple transparent sedimentation columns for visual observation and measurement of particle settling rates. It is ideal for Civil, Environmental, Chemical, and Process Engineering laboratories for understanding discrete and hindered settling phenomena.
Educational Objectives
Students and researchers will be able to:
-
Compare the settling characteristics of different types of particles.
-
Determine the effect of concentration on sedimentation (hindered settling).
-
Plot velocity distribution curves for various sediments.
-
Study flocculent and discrete particle suspension behaviors.
-
Establish particle size distribution and verify sedimentation theories.
Performance Measurement
-
Measurement of settling time and sedimentation depth.
-
Observation and recording of settling curves for different materials.
-
Determination of settling velocity and comparison with theoretical results.
-
Analysis of particle size distribution using experimental data.
-
Evaluation of the effects of temperature and viscosity on settling rate.
Panel and Instruments / Components
-
Sedimentation Columns: Five transparent removable columns mounted on a rigid support frame.
-
Back-Illuminated Panel: Translucent panel with uniform lighting to enhance visibility.
-
Graduated Scale: Printed scale along each column for accurate measurement of settling depth.
-
Accessories: Stopwatch, measuring beakers, specific gravity bottle, and rubber bungs.
-
Drain Valves: Fitted at the base of each column for easy emptying and cleaning.
