Learn about chemical dosing odour control and how it works

Chemical dosing is an effective way of reducing odours in large and complex systems. Find out how it works and where it is effective.

What is a chemical dosing system for odour control?

The system comprises of two key components; the control panel and the dosing pump. The control panel is used to set parameters such as flow rates, reagent concentrations and contact time. The dosing pump is used to inject the reagent into the wastewater at a controlled rate.

There are many different types of chemical dosing systems, each with their own advantages and disadvantages. The most common type of system is the aerobic system, which uses oxygen to control septicity. Other types of systems include anaerobic, nitrifying, and denitrifying systems.

Aerobic systems are the most common type of chemical dosing system for odour control. They use oxygen to control septicity and are typically used in wastewater treatment plants. Aerobic systems are advantageous because they are relatively simple and easy to operate. 

Anaerobic systems use bacteria to break down sewage. They are typically used in septic tanks and anaerobic digesters. Anaerobic systems do not require a constant supply of oxygenm making them the best choice where air supply is restricted.. 

Nitrifying systems use bacteria to convert ammonia into nitrites and nitrates. They are typically used in wastewater treatment plants. Nitrifying systems are highly effective at removing ammonia from wastewater. 

Denitrifying systems use bacteria to convert nitrites and nitrates into nitrogen gas. They are typically used in wastewater treatment plants to remove nitrates from wastewater. 

Choosing the right chemical dosing system for your needs depends on a number of factors, including the type of wastewater you are treating, the concentration of pollutants in the wastewater, the volume of wastewater you need to treat, and your budget. If you are not sure which type of system is right for you, consult with a wastewater treatment expert at CleanaWater today.
