Urban wastewater treatment is the process of eliminating pollutants from surface runoff (storm-water) and household wastewater. The goal of this process is to produce

Environment-friendly fluid waste and solid waste suitable for disposal or reuse. Physical, chemical and biological methods can be used in the treatment process to remove physical, chemical and biological pollutants. The treated sewage (or effluent) is expected to be reused for various purposes such as irrigation, or even used as drinking water after further treatment.

Harms of foam in urban wastewater treatment

Foam in urban wastewater treatment can lead to a series of problems. Foam can disturb the operation of treatment factories, causing clogging of pumps and piping, reducing the efficiency of the treatment process. It is possible to introduce pollutants into waterways, causing water pollution. Additionally, foam can cause unpleasant smells and create an unsightly appearance in waterways.

Benefits of defoamers and antifoams for urban wastewater treatment

Defoamers are used in urban wastewater treatment to decrease the amount of foam on the water surface. Problems such as decreased efficiency of the treatment process, accrued energy costs and accrued sludge buildup are all caused by foam. The operating principle of defoamers is to destroy the surface tension of bubble, causing it to collapse and disperse. This decreases or eliminates foam on the surface, allowing the treatment plant to operate more efficiently.

What kind of defoamer can be used for urban wastewater treatment?  Silicone antifoams or non silicone defoamer solutions? They have their own characteristics, which depends on the specific conditions. Please contact us for more details!
