Separation of Substances (Smart Automated Centrifuge & Filtration Plant)

Source:

Build a smart 3-stage water & mixture separation plant! Separate muddy water using sedimentation, an optical turbidity-guided filtration column, and a high-speed DC motor centrifuge that separates chalk/blood cells from liquid.

Categorisation

Props & Materials Required

  • •Mini 12V high-speed DC motor centrifuge module with tube rotor
  • •3-layer filtration column (Sand, Charcoal, Gravel)
  • •TS-300B optical turbidity sensor module
  • •ESP32 controller board
  • •16x2 LCD display screen
  • •DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Load Muddy Mixture into Filter

Pour muddy water into the 3-layer Sand/Charcoal filtration column.

2

Measure Filtered Water Turbidity

Turbidity sensor reads water clarity improving from 850 NTU (MURKY) → 15 NTU (CLEAR).

3

Load Test Tube into Centrifuge

Place chalk water sample tube into the DC motor centrifuge rotor.

4

Run 2000 RPM Centrifuge Spin

Spin centrifuge at 2000 RPM for 15 seconds. High G-force forces chalk powder to form a solid pellet at the bottom! LCD displays 'CENTRIFUGAL SEPARATION COMPLETE!'

Why It Works & Notes

Separating mixtures relies on physical differences (particle size, density, centrifugal force). Using optical turbidity sensors to monitor water clarity before and after filtration/centrifugation makes chemical separation measurable.
