The best media for gas/liquid contacting.

Mott porous metal media– the best method of achieving high-efficiency gas/liquid contacting. For decades, Mott porous metal spargers have been the fast, reliable, cost-effective choice for gas/liquid contacting in all sorts of industries. Here are a few reasons why:

Small bubbles transfer gases faster, more efficiently.
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 greater gas/liquid contact area, which reduces the time and volume required to dissolve gas into liquid.
    With thousands of pores over the surface, large volumes of gas can be passed with very high specific area. For example, with equal volumes of gas, 1mm bubbles would have 6.35 times more gas/liquid contact surface area than 6.35mm (¹/₄") bubbles.

All-metal construction lasts for years.
Mott spargers are constructed entirely of metal, to provide long-lasting operation even in the midst of temperatures as high as 1450°F under oxidizing conditions. And for inert and corrosive media, Mott offers a wide range of materials including 316L stainless steel (standard), Nickel 200, Monel^® 400, Inconel^® 600, Hastelloy^® C-22/C-276/X and Alloy 20.

Conventional drilled pipe spargers (left) produce poorly dispersed, large, fast-rising bubbles with very low surface area. Mott porous metal spargers (right) create millions of small, slowly rising bubbles, with significantly more surface area, resulting in more complete and rapid mass transfer.

Simple, cost-effective, easy-to-install.
Mott spargers typically consist 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 manifolded systems, Mott spargers are among the simplest, most affordable and most efficient gas/liquid contacting solutions available anywhere.

All sizes and configurations.
Mott spargers are designed, manufactured and finished at Mott. So if you need a non-standard size, or a special fitting, Mott has the capability to accommodate your request.

Oxygen stripping, using nitrogen. Actual performance data shows the superiority of Mott porous metal spargers, compared to drilled pipe spargers. Much higher performance levels with significantly lower gas consumption.
