With the increasing awareness of environmental protection and the continuous progress of water treatment technology, the performance requirements for defoamers used in water treatment are also increasing. In recent years, researchers have been committed to developing more efficient and environmentally friendly new defoamers to meet the application needs in different scenarios.

Using natural polymer materials as substrates, defoamers with excellent biodegradability and environmental friendliness are developed through modification or composite technology. Such defoamers can not only effectively control foam, but also promote the biodegradation of organic pollutants in water to a certain extent.

Introducing nanoparticles into defoamer systems can significantly improve their dispersibility and stability, enhance their defoaming and anti foaming abilities. The introduction of nanomaterials can also endow defoamers with more functionality, such as antibacterial and self-cleaning properties. Developing defoamers that can automatically adjust their defoaming performance according to environmental changes, combined with intelligent material technology. This type of defoamer can work efficiently under specific conditions, while maintaining low activity under other conditions, thereby reducing unnecessary consumption and environmental pollution.

The use of biosurfactants produced by microbial fermentation as the main component of defoamers has the advantages of being completely biodegradable, non-toxic, and harmless. Through genetic engineering and other methods, the defoaming performance of these biological surfactants can be further optimized to make them more suitable for complex water treatment environments.

Although defoamers play an important role in improving treatment efficiency and ensuring water quality safety, their correct use and maintenance management cannot be ignored to ensure optimal results and long-term stable operation.

Based on the water quality analysis results and treatment process requirements, accurately calculate the required dosage of defoamer to avoid waste or negative effects caused by excessive use. Select a suitable adding point, usually before or at the initial stage of foam formation, and add it evenly through the metering pump to ensure the uniform distribution of defoamer. Ensuring thorough mixing of defoamers with water can be achieved by increasing stirring or aeration time.

Regularly check the water quality and foam condition, evaluate the effect of defoamer, and adjust the dosage or change the type if necessary. Keep the defoamer dosing equipment clean and in good operating condition to prevent blockage or leakage. Operators need to be familiar with the safety operating procedures of defoamers, wear necessary personal protective equipment, and avoid direct contact or inhalation. For the waste liquid of defoamers after use, it should be properly disposed of in accordance with relevant environmental regulations to avoid polluting the environment.

In summary, the correct use of defoamers for water treatment is the key to ensuring efficient and stable operation of water treatment systems. Through continuous research and development, exploration, and innovation, more high-performance and environmentally friendly defoamers will emerge in the future, contributing to the development of water resource protection and water treatment industries.
