Foam Suppression

Foam is a mass of small bubbles of gas formed on the surface of a liquid. Foam generation is a problem that can affect productivity in a wide range of industries such as in the chemical, food and beverage and wastewater sectors.

One of the most common foam control methods is the use of spray nozzles, which must be correctly identified and sized to achieve the best performance. In particular, before selecting a specific product, it is necessary to know the desired spray coverage as well as the droplets dimensions and to reduce the risk of clogging.

Foam is undesirable because it can overflow vessels, create slippery and unsafe working conditions, interfere with processing, damage materials, and cause tanks to drain and dry slowly.

Controlling foam can be accomplished by nozzles to spray liquid onto the surface of the vessel, tank, pool or reservoir and allowing the droplets of the spray to impact the foam bubbles, causing them to break.
