Pronunciation: [spˈɑːd͡ʒə] (IPA) 
The word "Sparger" is spelled with two syllables, pronounced as /ˈspɑː(r)ɡər/. The first syllable is stressed and begins with the "s" sound, followed by the "p" sound. The second syllable begins with the "a" sound, and is followed by the "r" sound and a soft "g" sound, before ending with the "er" sound. This word is typically used in the chemical engineering field, referring to a device used for injecting gas into a liquid.
A sparger is a device used to introduce gas or liquid into a liquid or solid medium in various industrial and scientific processes. It is typically designed to generate fine bubbles or droplets for the purpose of mixing, agitation, or aeration.
In the context of liquid mixing, a sparger is commonly used in fermentation, bioreactors, or chemical reactors to introduce gases such as air, oxygen, or carbon dioxide into the liquid medium. The sparger, usually made of stainless steel, consists of small openings or perforations that release gas in the form of fine bubbles, promoting efficient mass transfer and homogenization of the liquid. This allows for optimal microbial growth, improved reaction rates, and enhanced product yield.
In the field of environmental engineering, a sparger is employed as part of groundwater remediation systems. It is used to inject air or oxidizing agents into contaminated groundwater, aiding in the breakdown or removal of harmful pollutants through a process called in situ chemical oxidation.
Additionally, spargers can be utilized in water treatment processes to introduce chemicals or disinfectants such as chlorine, ozone, or hydrogen peroxide into water streams, ensuring effective sterilization and decontamination.
Overall, the sparger plays a crucial role in various industries and scientific applications, enabling the controlled introduction of gases or liquids for enhanced mixing, aeration, and chemical reactions.
A vessel with a perforated bottom, used for dashing or sprinkling water.

The word "sparger" derives from the Latin verb "spargeō", which means "I sprinkle" or "I scatter". It is derived from the Proto-Indo-European root *sperg-, which also means "to sprinkle" or "to strew". The term "sparger" refers to a device or apparatus used for dispersing a liquid or gas into small particles or bubbles, typically in the context of mixing or aeration processes in various industries such as food, pharmaceuticals, and wastewater treatment.
