Biological water treatment is a solution that eliminates contaminants from wastewater by means of living organisms. This type of treatment is commonly used in industrial settings that generate large volumes of wastewater, such as food processing factories. The solution works because the organisms used in the process consume the contaminants and break them down into harmless by-products. In contrast, biological water treatment is more effective and cost-effective than chemical treatment. What’s more, it also helps to decrease the environmental impact of wastewater treatment.

Hazards of foam in Biological Water Treatment

If foam occurs during biological water treatment, it will lead to all kinds of problems. First of all, foam can block the filter and then reduce the contact between the water and the biological media. Then a host of problems will ensue, such as preventing oxygen from reaching the organisms responsible for breaking down the pollutants, preventing the organisms from doing their job and reducing the efficiency of the treatment process. Foam also has the potential to create an environment where bacteria and other microorganisms can multiply, leading to increased levels of disease-causing pathogens in treated water. Finally, the foam may interfere with the chemical treatments used to disinfect the water, resulting in more residual disinfection by-products.

Benefits of defoamers and antifoams for biological water treatment

Defoamers with high antifoaming efficiency, are important chemical additives for biological water treatment. Defoamers from Rickman have good diffusivity and permeability, complete compatibility and strong oxidation resistance. They help decrease the amount of foam produced when organic materials are broken down by bacteria, thereby preventing inefficiencies caused by foam. Defoamers also help decrease the number of air bubbles emerged during aeration, which can cause oxygen transfer and lead to poor water quality. Finally, defoamers help prevent foaming on tanks and other equipment surfaces, which may result in safety hazards and accrued maintenance costs.

Product property of defoamers and antifoams:
Excellent instant defoaming ability and long antifoaming persistence
Suitable for various of foaming system
Chemically inert
Good stability
