Compounds that contribute significantly to environmental pollution include fragrances, commonly referred to as smells, and volatile organic compounds. Due to their limited solubility in water and high vapour pressure, they are gaseous pollutants and chemical vapours. Odour removal plays a huge role here.

Urbanized regions are most affected by the smells, which are caused by the burning of hydrocarbon fuels, the chemical and petrochemical industries, as well as mining, municipal, food processing, and agricultural waste.

Waste management facilities, wastewater treatment facilities, as well as food and agricultural processing facilities, are the industries with the biggest odour nuisance. Humans can detect odours at extremely low concentrations thanks to a combination of volatile molecules known as odorous gases. 

All living things, notable humans, are affected by them significantly, which results in health issues. Due to odour annoyance, odours can also harm mental health. They are poisonous, carcinogenic, and mutagenic.

 

Wastewater Treatment Facilities Odour: What Causes It?

Companies from the municipal sector, such as wastewater treatment plants, waste management plants, or composting plants, are among the facilities that release the most persistent hazardous gases. These odours are often caused by the anaerobic breakdown of organic molecules. 

The hydrogen sulphide, a byproduct of decomposition, that most people associate with these facilities gives forth a pungent stench. Other substances which produce odours from municipal wastewater treatment facilities are as follows –

  • Sulphur compounds, such as hydrogen sulphide, thiols, sulphides, and alkyl disulfides.
  • Nitrogen compounds, such as ammonia and aliphatic amines.
  • Organic compounds, such as aldehydes, ketones, and fatty acids (phenol, butyric acid, acetic acid etc.)

Hydrogen sulphide gas, which smells like rotten eggs, is released by inlet collecting areas or pre-treatment systems, including but not limited to sewage collection tanks, screening, and grit removal stations. Low solubility in wastewater causes it to be discharged into the atmosphere, where it produces an unpleasant odour.

 

What Negative Effects Might Uncontrolled Odour Cause?

Even while the plant’s immediate vicinity contains many smells, some odours inevitably migrate outside of it. In the years after the facility was constructed, neighbourhoods and public parks have been erected nearby. It makes sense that communities don’t tolerate these obnoxious smells, which leads to complaints. 

Citizens frequently phone the factory to urge management to find a solution, or they contact politicians and the media, depending on how bad the smells are. The reputation of the facility and the brand might be harmed by odour complaints that cross the line into politics and/or obtain unfavourable media coverage.
There is a risk that these odours will become worse if precautions like air purification are not taken. Heat, humidity, and strong winds are a few weather factors that might make the issue worse. Most complaints about wastewater facilities often occur in the summer, but maintenance and control procedures must be effective all year round.

 

How to Reduce Odour and Chemicals?

Setting up a proper odour control unit for the wastewater treatment plant is the best way to control odour. The odour control equipment releases odourless air into the atmosphere after extracting odorous gases from collection tanks or a defined region. 

There are many effective odour control technologies on the market, including biological oxidation systems, chemical scrubbers, and activated carbon adsorption. However, picking the appropriate odour control technology is crucial if the plant is to effectively remove odours and operate at a low cost.  

Using an ozone generator can help you remove unpleasant. Some of the odour control units – Ozone generators are as follows –

Treatment Of Hydrogen Sulfide, Ammonia, And Odour From Wastewater – Model 2000T

According to the total duct airflow needed for the application, AirMaid is available in several variants. If the duct has many branches, give each one the model that is appropriate for its airflow. This allows us to maintain a constant concentration of ozone (usually between 0.5 and 1.0 ppm) throughout all duct system portions. 

The “fuel” used by the AirMaid generator to produce its ozone must be purified before it is delivered to and flowed through it. Utilize the least polluting air supply possible to reduce the need for equipment maintenance.
