Sparging is another one of the three main inerting applications, used to strip oxygen from liquids such as oils, beverages, chemicals and wastewater. Sparging involves passing finely dispersed gas bubbles through the liquid. This helps to improve mixing and increase the surface area for gas-liquid mass transfer. Consequently, this technique is not just used to strip oxygen from liquids, but also to intensify chemical and biological reactions.
Sparging can be used to preserve the quality and longevity of food products by eliminating undesirable substances and inhibiting unwanted chemical reactions with oxygen. In the chemical industry, injecting a stream of fine gas bubbles is a fast, flexible and effective way to boost a chemical or biological reaction by increasing the available surface area between the two phases. This inerting process can also be used in wastewater treatment to boost the effectiveness of anaerobic activity.
What industries rely on sparging?
Many industries use sparging to remove oxygen from process water and thus protect pipes against corrosion. Food, chemicals and wastewater management are increasingly looking for ways to replace harsh physical or chemical preservative methods with less severe alternatives. Inert gases such as nitrogen, carbon dioxide and argon are excellent ways of resolving the oxidation challenge in these sectors without adding any reactive substances to the liquid in question.
What gases are best for sparging?
The inert gases nitrogen, carbon dioxide and argon are generally used for sparging beverages. Nitrogen is typically employed for sparging wastewater and in chemical and biological applications.
