Typical problems with gas flotation systems originate from poor selection of technology and a lack of understanding regarding unit design.  Central to all Howe Baker produced water treatment technology is a comprehensive understanding of the process.  Our flotation systems are designed to optimise oily water skimming and minimise risk of “short circuiting”.

We supply a full range of gas flotation technology including internals and external eductors, baffles, diffusers and gas dispersion devices which are core to our Single and Multi Cell IGF Units and Dissolved Gas Flotation Units

Howe Baker’s Induced Gas Flotation vessels are designed for polishing of produced water removing both emulsified oil droplets and fine solids particles. They are well proven for high performance separation. Our flotation vessels are designed for a wide range of applications. Pressure, temperature, flow rates, oil/solids concentration and sludge handling capacity all affect the performance of flotation vessels. Each Howe Baker flotation device is designed to meet the unique project challenges whilst delivering a compact and energy efficient solution.

OPERATION

Our hydraulic Induced Gas Flotation systems operate by recycling cleaned water downstream of the IGF. Recycled water passes through eductors that draw fuel gas from the vessel head space and recirculate it for flotation. Recycled water flows to the bottom of the vessel through bespoke diffusers which generate micro gas bubbles to ensure efficient gas sparging of each flotation cell.

The entrained gas bubbles float oil droplets to the surface of the water where they form an unstable foam/ scum. Gas is released into the vessel head space for recirculation the foam and oily water scum are removed by overflowing a weir into an oily water collection compartment.

Separation takes place in multiple flotation cells, the number of cells necessary is dependent upon the application and process conditions. Each flotation device is uniquely designed to meet the individual project challenges and outperforms other products.
