Features Of Solvay Clearbreak PG 4 Surfactant

  1. Highly effective nonionic surfactant designed for rapid and complete emulsion breaking in industrial water treatment systems.

  2. Low foaming profile ensures compatibility with high-shear processes and avoids interference with downstream separation equipment.

  3. Thermally stable across a broad operating temperature range (5–80 °C), maintaining performance under varying process conditions.

  4. Biodegradable formulation aligned with EU Ecolabel and OECD 301B guidelines, supporting sustainable operational practices.

  5. Compatible with common coagulants, flocculants, and hydrocarbon-based contaminants without precipitation or phase separation.

Typical Applications Of Solvay Clearbreak PG 4 Surfactant

  1. Oil-water separation in refinery wastewater treatment plants.

  2. Demulsification of produced water in upstream oil & gas operations.

  3. Emulsion breaking in metalworking fluid recycling systems.

  4. Pre-treatment of industrial effluents containing lubricating oils or cutting fluids.

  5. Enhancement of dissolved air flotation (DAF) efficiency in food processing wastewater streams.
