DuoBent F2

---

DuoBent is a European-scale eco-innovation. It’s a product designed for optimizing wastewater treatment processes, both in municipal and industrial applications. These products are manufactured using a patented technology to ensure their safe usage.

Application

The issue of sedimentation in secondary clarifiers can occur periodically or throughout the year. Causes may include factors such as an overload of pollutant load, the formation of sticky sludge due to the mass appearance of filamentous bacteria, or the formation of stringy sludge caused by excessive growth of filamentous bacteria. Commonly used coagulants for improving sedimentation are not always sufficient. Therefore, when an immediate improvement in sediment settling is necessary, the natural group of aluminosilicate mixtures called DuoBent comes into play.

DuoBent F2 is dedicated as an alternative to DuoBent F500 for wastewater treatment plants with a capacity exceeding 100,000 RLM that are facing issues related to the sedimentation of activated sludge and the influx of surface-active agents, which significantly contribute to the formation of foam on the surface of biological reactors.

Wastewater treatment plants of this kind, serving large urban areas, receive a higher inflow of pollutant load, including from various industrial sectors. Periodic issues with the sedimentation of activated sludge can occur for several operational reasons, such as pollutant overload, increased temporary inflow of wastewater or rainwater, the acceptance of campaign wastewater, treatment plant capacity limitations, or ongoing modernization works.

Experiences with wastewater treatment plants have shown that DuoBent F2 may also prove to be an effective solution for facilities receiving industrial wastewater, which, in a relatively short period or periodically throughout the year, receive significant pollutant loads. Often, biological treatment systems are not adapted to handle increased inflows, even when they occur temporarily.
