Water treatment odour control is an essential aspect of managing and eliminating unpleasant smells that can arise from various water treatment processes. These odours may result from the presence of certain chemical compounds or the growth of micro-organisms in the water. Controlling these odours is important for ensuring a better experience for water consumers and maintaining the overall effectiveness and safety of the water treatment process.


Aeration involves exposing water to air, which helps release volatile compounds responsible for odours. This method is particularly effective for reducing odours caused by dissolved gases like hydrogen sulfide (rotten egg smell).

Chemical oxidants, such as chlorine, ozone, or potassium permanganate, can be used to break down organic compounds causing odour. These oxidants react with odorous substances, neutralizing or converting them into less odorous compounds.

Activated carbon filters are effective in removing organic compounds and some chemical pollutants that cause foul odours. The porous structure of activated carbon traps odour-causing substances, leaving the water odour-free.

These filters use beneficial microorganisms to biodegrade organic compounds that cause odours. The microorganisms break down the odorous substances into harmless byproducts.

Proper pH control can help minimize the release of volatile compounds and reduce odour in water.

Stripping towers involve passing air through the water to encourage the transfer of volatile odorous compounds from the water to the air.

Ultraviolet (UV) light can be used as a disinfection method, which can also help in reducing some odours caused by microorganisms.

Proper management of water reservoirs can help prevent the formation of odorous compounds by controlling factors such as temperature, organic matter, and nutrient levels.

Addressing the source of odour-causing substances, such as industrial discharges or agricultural runoff, can help reduce odours in the water treatment process.

Regular monitoring of water quality, including odour assessments, can help identify potential issues early and implement appropriate odour control measures.

It’s important to note that the effectiveness of odour control measures may vary depending on the specific odour-causing compounds present in the water and the treatment process used. Our Water treatment professionals can help identify the best odour control strategies based on water quality analysis and specific treatment goals. Additionally, compliance with local regulations and guidelines is essential for implementing appropriate and safe odour control practices in water treatment facilities.
