Pumps: Pumps meant to transport liquids can suffer from cavitation if foam is present because the pump can end up moving a mix of liquid and air. Over time, this can depress performance and even cause mechanical damage.

Mixers: Foam can affect the performance of mixers, preventing them from achieving a uniform mixture. This can lead to subpar outcomes and possible damage due to uneven load distribution.

Heat Exchangers: Foam can cause inefficient heat transfer in heat exchangers. This can lead to overheating and premature wear or deformation of parts.

Fillers: In packaging operations, foam can slow down and disrupt the filling process, leading to inaccuracies in quantities and potential damage to the filling machinery through excessive pressure or overflow.

Filters: Filters can be clogged by foaming liquids, reducing their efficiency drastically. In the worst case, they can be damaged due to pressure build-up.

Reactors: In chemical process reactors, foam can limit the efficient mixing of reactants or cause inaccurate measurements, potentially leading to chemical imbalances, spills, or even hazardous situations.

Separators and Clarifiers: In operations requiring separation of liquid phases or clarification (removal of solids), foam can severely impair the process, leading to longer processing time, equipment stress, and poor product quality.

Conveyor Systems: In operations where liquids are transported via conveyor systems, foam can result in messy spills and residue that requires constant cleaning, causing wear and tear to the equipment and slowing down the convection process.
