Acoustic Energy Oil–Water Separation

Oil–water emulsions are a costly, persistent problem across the refining, storage, and waste management industries. Traditional treatment methods rely on chemical demulsifiers, long settling times, or heavy centrifuges — all of which add cost, waste, and complexity.

How it works

The process uses precisely controlled energy and gentle conditioning to destabilise emulsions without harsh chemicals or complex reagents.

Conditioning

A small dose of our proprietary additive is introduced to the emulsion to pre-condition the mixture for separation.

Heating

The sample is gently heated to the optimum operating range (typically 50–70 °C) to improve flow and energy transfer.

Acoustic Energy Cavitation

High-frequency acoustic waves create microscopic pressure zones within the fluid. These disrupt the molecular bonds that stabilise the emulsion.

Phase Separation

The oil rapidly coalesces and rises, forming a clean top layer. Water clarifies beneath, with any fine solids settling to the bottom.

Performance Results

Laboratory and pilot trials have demonstrated rapid, visible phase separation immediately after ultrasonic treatment:

Clear oil–water interface formed within 5–20 minutes

Complete three-layer structure: oil (top), water (middle), solids (bottom)

No chemical demulsifiers or centrifuges required

High oil recovery and minimal secondary waste

Effective across a wide range of oil viscosities and contamination levels

Observed Outcome

After a short settling period, the treated sample forms distinct clean layers, confirming
complete and stable phase separation using acoustic energy alone.

Economic and Environmental Value

TST’s acoustic separation technology replaces costly, chemical-heavy treatment with a clean, circular process.


Recovered oil is returned to use, clean water is safely discharged or reused, and minimal solids are sent to disposal. This approach cuts operational costs, eliminates confined-space risk, and aligns with environmental targets for waste reduction and carbon impact.
