Equipment
Induced Gas Flotation (IGF)
Heavy-duty flotation for produced water and hot oily streams.
Overview
IGF uses a high-energy vortex to induce and shear gas into micro-bubbles without a pressurisation system. It is the proven workhorse for produced water, refinery and high-temperature oily wastewater.
How It Works
Process flow and treatment mechanism in simple steps:
- 1
Wastewater enters flotation cells with mechanical or hydraulic gas induction.
- 2
A vortex shears gas into fine bubbles that attach to oil droplets.
- 3
Oil and solids rise as froth and are skimmed from the surface.
- 4
Treated water exits for discharge, reuse or downstream polishing.
Applications
Industries and situations where this product is ideal:
- Oil and gas produced water
- Offshore platforms
- Refineries and petrochemical plants
- Ballast water treatment
