Liquid jet Gas Compressors for Gas Micro Bubbling

Gas Micro bubbling is a specialized technique which involves dispersing gas into a liquid in form of very small gas bubbles.
Gas Micro Bubbling is commonly implemented for the following

  1. To accelerate gas-liquid reactions in the Chemical Industry and Pharmaceutical Industry.
  2. To promote oxygen dissolution in water in water treatment plants
  3. To pump air into a centrifugal pump to avoid cavitation.
  4. For accelerating dissolution of gases in liquids.

Achieving micro bubbling is complicated and it involves first pumping gas into liquid and then ensuring that the gas splits itself into small bubbles and disperses evenly through the liquid.

Liquid jet Gas Compressors are simple devices that operate on the basis of the jet Venturi principle.
Liquid jet Gas Compressors utilize the energy in pumped liquid for their operation, the liquid is supplied to the ejector at medium to high pressures.

During operation the Liquid jet gas Compressor sucks the gas through its suction inlet, mixes the gas with the pumped liquid and discharges a gas + liquid mixture through its outlet. The internal mixing process happens rapidly and experiences large shearing force between the gas and liquid. These shearing forces have the capability of breaking the gas volume into fine bubbles.
By carefully designing the Liquid jet gas Compressor’s internal geometry and by regulating the operating pressures it is possible to have an outlet flow comprising of fine gas bubbles dispersed in the liquid.
It is possible to achieve a min bubble size of 50 µm or 0.05mm through a Liquid jet gas Compressor.

Liquid jet Gas Compressors are best suited for gas micro-bubbling applications because of their inherent characteristics.
• Ability to produce a uniform flow of micro gas bubbles dispersed evenly through the liquid.
• Suitable for both batch type and continuous operation.
• Can be manufactured in a large range of materials (Plastics, Stainless Steels, Exotic Materials)– it helps to select the best possible material compatible with the involved chemicals and reduces the risk of corrosion
• Liquid jet Gas Compressors do not contain any moving parts and have large internal passage areas, hence are not vulnerable to liquid entry or clogging by solid particles.
• As they have no moving parts, maintenance requirements are very less. Also it reduces largely the risk of abrupt breakdowns, helps in maintaining the regular production schedule.
