In-Line Spargers

Mott GasSaver in-line spargers increase gas absorption by as much as 300% over traditional sparging technologies, resulting in faster throughput and less gas usage. These in-line spargers can be used with virtually any gas or liquid to improve gas absorption in a variety of processes. Because porous metal provides thousands of flow paths, gas exits through the in-line spargers in very small bubbles, resulting in far better absorption than traditional sparging technology. These in-line spargers can be installed directly in-line with your fluid path or intrusively into piping, offering flexible integration into existing systems for enhanced efficiency.

Sparging Overview

Mott's overview of sparging technology, configurations, and applications.

Sparging Design Guide

High surface area means fast, efficient mass transfer. The key to high-efficiency sparging is fine bubble propagation which provides maximum surface area for effective "mass transfer." Mott precision porous metal creates fine bubbles over a broad range of application requirements. This is Mott's Sparging Design Guide.

FAQs: In-Line Spargers

Q: What are in-line spargers?

A: In-line spargers are specialized devices designed to efficiently introduce gas into a liquid through thousands of tiny pores, creating extremely fine bubbles. This process maximizes the gas-to-liquid contact area, significantly improving the efficiency of gas absorption and mixing in various industrial processes.


Q: How do in-line spargers work?

A: In-line spargers work by forcing gas through a porous metal element directly installed in the fluid path. As gas passes through the porous material, it is dispersed into fine bubbles, which then mix with the liquid, facilitating efficient gas dissolution and ensuring uniform gas distribution within the liquid.

Q: What are the benefits of using in-line spargers?

A: The benefits of using in-line spargers include enhanced gas dissolution rates, increased process efficiency, reduced gas consumption, and improved product quality. They also minimize the risk of clogging and ensure a consistent bubble size, which is critical for processes requiring precise gas-liquid mixing.

Q: Where are in-line spargers typically used?

A: In-line spargers are used in a wide range of applications, including chemical processing, pharmaceutical manufacturing, wastewater treatment, and food and beverage production. They are ideal for any process that requires efficient gas mixing, oxygenation, or aeration.

Q: Can in-line spargers be customized for specific applications?

A: Yes, in-line spargers can be customized to meet specific process requirements, including the size, shape, and porosity of the porous element, as well as the material composition to handle different gases and liquids. This customization ensures optimal performance in specific applications.

Q: How do I choose the right in-line sparger for my application?

A: Choosing the right in-line sparger involves considering several factors, such as the type of gas and liquid involved, desired bubble size, flow rates, and the specific requirements of the process. Consulting with a Mott representative can help identify the most suitable in-line sparger design for your application.
