Micro-bubble Generation & Vessel Gas Recovery
Ejectors can be used to perform a number of duties in the oil flotation process. This is typically a late-stage water treatment process to remove any remaining oil or particles from water. Oil or particles naturally ‘stick’ to bubbles, which then rise to the top of the flotation unit (vessel) to be skimmed.
Transvac has developed a special ‘micro-bubble generating’ ejector device capable of producing optimised, ultra-fine bubbles. With a huge surface area created, a more efficient flotation process is observed. Where excess gas needs to be recovered from the flotation vessel, a second ejector is available to compress and recover this gas.
Our Research & Development Team have carried out an in-depth development project to advance our micro-bubble Ejector designs. This involved the used of CFD followed by real world testing in our Ejector Test Facility. The facility includes a dedicated CFU (Compact Flotation Unit), with laser-probe measurement to assess bubble size and distribution.
