  1. Why Should I Use Water-Based Defoamers?

    Comments Off on Why Should I Use Water-Based Defoamers?

    Defoamers play a critical role in ensuring foam does not affect the quality of products and processes during industrial applications. They are available in many variations to suit different operations, including oil-based, surfactant-based, and water-based. Below, we focus on water-based defoamers, outlining what they are and what benefits they offer.

    What Are Water-Based Defoamers?

    As suggested by the name, water-based defoamers utilize water as the carrier, or continuous phase. They typically contain between 60% to 95% water. Many of them are technically oil-in-water emulsions, and therefore contain some form of fat or oil (e.g., mineral oils, vegetable oils, and natural or synthetic waxes). By using water as the carrier and presenting these active ingredients in an emulsified form, these defoamers can more easily disperse into water and water-based process media, and effectively suppress foam.

    Advantages of Water-Based Defoamers

    Compared to other types of defoamers, water-based defoamers offer a number of advantages, such as:

    • Lower cost. Water is the least expensive ingredient that can be added to a formulation, and water-based defoamers can sometimes be made from the byproducts of other manufacturing applications, making them cheaper and easier to produce.
    • Ease of Application. They often require minimal production equipment to dilute to lower concentrations, making them simpler to use. 
    • Better performance. They easily disperse in water and water-based solutions to provide foam suppression and deaeration. Additionally, they do not typically contribute to deposition that can lead to equipment malfunction, product damage, or quality issues.  
    • Broader compatibility. They are suitable for use in a wide range of industries and operations, from paper processing to industrial process water to wastewater treatment. They can provide defoaming action across a variety of temperatures (typically up to 160° F) and pH levels.  
    • Greater environmental friendliness. Many water-based defoamers do not contain harmful components, and they tend to have little to no impact on the environment. Additionally, many variations can be considered biodegradable, thereby allowing for their use in more environmentally-sensitive applications. 

    Industrial Applications of Water-Based Defoamers

    While water-based defoamers were first used in the paper industry, they have since found application in many other industries due to their low cost, environmental friendliness, biodegradability, and other advantageous properties. Today, in addition to the paper industry, they are commonly used in the following industries and applications:

    • Agriculture
    • Parts washing
    • Food and beverage
    • Chemical manufacture
    • Water and wastewater treatment
    • And more!
