Waste Water Physical Separation is the initial stage in wastewater treatment that aims to separate solids or suspended substances from wastewater without using chemical or biological reactions. This process relies solely on physical forces such as gravity, filtration, or centrifugal force.

A more detailed explanation follows:

Main Objective

Remove large objects and solid particles so that they do not damage or interfere with subsequent treatment processes (e.g. biological or chemical processes).

Types of Physical Separation Processes

1. Screening

   • Screening out large objects such as plastic, wood, or cloth.

   • Tools: bar screen, coarse screen, fine screen.

2. Sedimentation

   • Utilizes gravity to settle heavy solid particles to the bottom of the tank.

   • Result: sludge at the bottom, clear water at the top.

3. Flotation

   • Uses air bubbles to float light particles (e.g. oil, grease) to the surface of the water.

4. Filtration

   • Filtering out small particles using media such as sand, gravel, or membranes.

5. Centrifugation

   • Uses centrifugal force to separate solids from liquids with a difference in density.

Application Example

• In industrial or domestic wastewater treatment plants, screening and sedimentation are usually performed first before the water enters the biological unit.

• For example: food factory wastewater → screened → sedimented → then enters the aeration tank.

Conclusion

Physical separation is an important step to reduce the pollutant load at the next stage and improve the overall efficiency of the wastewater treatment system.
