Use defoaming agent as Foam Control Solutions for Wastewater Treatment

Foam can cause havoc in many wastewater treatment systems. To combat it, the main methods to reduce it include spraying it out or physically removing it yourself, adding chemicals or using bioaugmentation techniques.

Defoaming agent work by decreasing surface tension that holds air bubbles together and breaking up existing foam into smaller bubbles.

Defoaming Agent

Foaming in water treatment slows down the process and may clog filtration systems, reducing efficiency. Antifoams and defoamers help address these problems by eliminating foaming issues; increasing efficiency by decreasing product contamination caused by air bubbles; as well as helping prevent product contamination by decreasing air pockets present within products. They can be added manually or automatically using peristaltic pumps that dispense precise amounts.

Defoamers are insoluble additives that spread rapidly along the surface of liquid foam to decrease its surface tension gradient, destabilize foam lamellae, rupture air pockets, and disperse into bulk liquid.

Defoamer are versatile products used in numerous applications, including wood pulping, oil and gas drilling, froth flotation, chemical manufacturing, textile wet processing (sizing, bleaching, dyeing and printing), metal working fluids and detergents to reduce foaming; textile auxiliaries like scouring aids wetting agents and print pastes can also benefit. Aqueous or nonaqueous systems may utilize defoamers.

Foam can be an enormously frustrating problem at wastewater treatment plants. Foam often results from the high hydrophobicity of microorganisms such as Nocardioforms and Microthrix parvicella present in activated sludge processes; their foam can be controlled using specific bacteriophages targeted to these organisms to increase their populations, rates of colonization, and effectiveness against slow moving pests; this technique is known as augmentative biological control and involves large scale releases to increase populations, rates of colonization rates and effectiveness against slow moving pests.

Chemical Control

Foam management is an essential step in industrial wastewater and process water treatment applications, where excessive foam can overflow vessels, interfere with processes and materials, create safety hazards in your operation and lead to pump cavitation resulting in downtime, shutdowns and equipment damage.

Defoaming agent and antifoaming agents are chemical processing aids designed to minimize or eliminate foam in industrial systems. While Defoamers work by disabling any previously formed foam, antifoam agents prevent its formation altogether at the outset of production.

Optimization

Foam control can be achieved easily by preventing its formation altogether, using headspace aeration systems as main gas-liquid surfaces (headspace aeration). Headspace aeration boasts an expansive tolerance or demand for carbon dioxide which makes it highly suitable to stop foam formation even with complex microorganism-based bioprocesses.

Chemical additives designed to prevent foam formation are also an option, typically applied as defoaming agents or antifoams. we offer foam inhibitors which are highly soluble, ready-to-use and do not need diluting prior to stage dosing – helping reduce overall adjuvant inventory while streamlining supply chain processes. our foam inhibitors was specially created to perform optimally at specific processing temperatures while offering both antifoam and defoaming capabilities allowing reduced dosage rates reducing costs significantly.
