Absolutely, alcohol-based defoamers are widely used in settling tanks as part of the wastewater treatment process. These defoamers offer practical benefits that make them ideal for such settings.

Rapid and Efficient Foam Control: As mentioned earlier, alcohol-based defoamers can quickly reduce the surface tension of the water, causing foam bubbles to collapse. This rapid action is particularly useful in scenarios where immediate foam control is necessary.

Compatibility with Treatment Processes: Their high volatility ensures they evaporate quickly after application, hence eliminating any lingering residues that could interfere with subsequent treatment stages or affect the quality of the treated water.

Broad Spectrum of Functionality: Alcohol-based defoamers operate effectively over a wide range of temperatures and pH levels. This flexibility makes them apt for various situations found in wastewater treatment processes.
