What is Biochemical Sewage Defoamer?

The main function of biochemical foam inhibitor is to eliminate and treat the foam produced in the process of biochemical sewage treatment. Foam problem is a common and troublesome problem in biochemical sewage treatment, which not only affects the treatment efficiency, but also may lead to water quality deterioration and increase the treatment cost.

Action Principle

Biochemical wastewater defoamers reduce the surface tension of liquid films, making foam membranes thinner and more prone to breaking. For example, some silicone-based defoamers can form a thin film on the foam surface, preventing gas from escaping and causing the foam to burst. Additionally, certain organic polymer-based defoamers can quickly adsorb onto the foam surface, altering its properties and reducing surface tension.

Applications

Biochemical foam inhibitors are widely used in various wastewater treatment plants, chemical plants, paper mills, and other industrial sectors. They can quickly eliminate foam, prevent foam overflow and leakage accidents, ensuring the stability and safety of the treatment process. At the same time, foam inhibitors can also improve oxygen transfer efficiency, enhance equipment performance, shorten processing cycles, and increase treatment capacity.

Effect and advantage

Using biochemical wastewater defoamers can significantly improve the efficiency of wastewater treatment, reduce the risk of equipment blockage and damage, and lower processing costs. Moreover, defoamers have good biocompatibility, do not negatively impact microorganisms, and are biodegradable, preventing secondary pollution. As technology continues to advance and application requirements evolve, the performance and application areas of defoamers are also expanding and optimizing.

Functions

1. Improve treatment efficiency: in the biochemical treatment process such as bioreactor and activated sludge method, an appropriate amount of defoamer can quickly eliminate the foam that affects the treatment effect, so that the biological reaction is more smooth, thus improving the treatment efficiency.

2. Environmental Protection: Foam in biochemical wastewater may contain harmful substances, such as incompletely decomposed organic matter and microorganisms. If these substances are released into the environment, they can cause irreversible damage to ecosystems. Defoamers effectively prevent the leakage of harmful substances by eliminating foam, thus protecting the environment.

3. Ensure equipment safety: The generation of foam may lead to equipment overflow and leakage accidents, affecting the normal operation of the equipment. Defoamer can effectively prevent this situation from happening, ensuring the stability and safety of the treatment process.
