Sparger

Fluid Controls supply a range of sparging equipment, including Mott Spargers. Mott spargers can be successfully applied to a wide variety of liquid and gaseous applications. Sparging, also known as gas flushing, is a technique which involves bubbling a chemically inert gas through a liquid. This is mostly used to remove dissolved gases, such as oxygen, from the liquid.

Mott Spargers

Mott spargers introduce gases into liquids through thousands of tiny pores, creating bubbles far smaller and more numerous than with drilled pipe and other sparging methods. The result is a greater gas/liquid contact area, which reduces the time and volume required to dissolve gas into liquid.

Mott sparging equipment typically consists of a porous metal element, a threaded fitting and, in longer units, a reinforcement rod. The design is simple, without moving parts. Installation is easy and requires no special tools. From single elements to manifold systems, Mott spargers are among the simplest, most affordable and most efficient gas to liquid contacting solutions available.

Mott sparger applications & industries

There is an array of applications and industries that benefit from gas sparging. These include:

• Aeration – Air sparging to meet biological oxygen demand on waste stream.
• Agitation – Air injection for mixing liquids in a vessel.
• Bioremediation – Air sparging to stimulate growth of bacteria for hazardous waste treatment.
• Carbonation – CO2 sparging for carbonated beverages and beer.
• Chlorine bleaching – Chlorine sparging for bleaching pulp in manufacture of paper.
• Column flotation – Air sparging for coal flotation, and other separations of solids.
• Dewatering – Nitrogen sparging to remove entrained water from motor oil.
• Fermentation – Oxygen or air sparging to enhance cell growth in fermentation reactions.
• Gas/liquid reactions – Sparging air, oxygen, or other gases into reactors for improved performance.
• Hydrogenation – Hydrogen sparging for a broad spectrum of chemical hydrogenation reactions.
• Oil flotation – Air or natural gas sparging for oil removal from produced water from oil wells.
• Oxygen bleaching – Oxygen sparging for bleaching pulp in manufacture of paper.
• Oxygen stripping – Nitrogen sparging to remove oxygen from edible oils, wine and juices. Oxygenation – Oxygen sparging in fish farming for significant stimulation of fish growth.
Ozonation – Ozone sparging to sanitize ultrapure water systems in pharmaceutical plants. pH control – CO2 or NH3 sparging to adjust pH in waste or process streams.
• Steam injection – Direct steam injection for efficient heating and to eliminate “steam hammer”
• Volatiles stripping – Air sparging for removal of VOC (Volatile Organic Compounds) from waste streams.

Gas sparging is a process that is utilised in a vast amount of common industries these include:

• Food and beverage
