This biofilter is used in a sewage treatment plant (WWTP) to control odour nuisance. In many urban and industrial areas, odour nuisance from wastewater and sewage treatment processes is a common problem. This odour can have a negative impact on the living environment and air quality. It is therefore essential to implement effective odour control systems.
The biofilter in this plant consists of two main components: a humidifier and the biofilter itself. The humidifier ensures that the air flow passing through the biofilter has the right humidity. This is crucial for the optimal functioning of the micro-organisms responsible for the biodegradation of odour components.
The biofilter itself consists of a biologically active medium that provides a suitable environment for the growth of micro-organisms. These micro-organisms break down odour components, such as hydrogen sulphide (H₂S) and other volatile organic compounds. This ensures that the air leaving the system is virtually odourless, which is essential for preventing odour nuisance in the surrounding environment.
Biofilters are particularly commonly used in sewage treatment plants (WWTPs) and small water treatment plants (KWZIs), especially in areas where the risk of odour nuisance is high. In these types of plants, biofiltration is considered one of the most effective, sustainable and cost-efficient methods to control odour, as it uses natural biological processes without the use of harmful chemicals.
The integration of this biofilter will ensure that odour nuisance from the wastewater at the WWTP is minimised, resulting in a cleaner and healthier environment for the surrounding community.
