The odour created from the wastewater system is because of hydrogen sulfide released in the form of gas. Moreover, hydrogen sulfide results in corrosion in collection systems and wastewater treatment plant equipment. Various emission sources also require odour control units like pump stations, sludge dewatering, manhole , etc.
The odour coming from sewage and effluent comprises hydrogen sulfide, and it is pretty dangerous when released in the environment. Odorous gas also consists of ammonia and organic Sulphur components.Even though most odours generally do not cause any physical health issues, malodour affects the surrounding, leading to complaints to the source.
This source of H2S emission is very much the same as VOCs, with the only difference being the Sulphur compound's presence. odour control units that are safe and efficient assist in solving complicated odour pollution. Their applications are mainly used to remove odour from the sewage treatment plant, sludge, paper &pulp industries, solid waste processing plant, etc. They will cover the foul odours and help you get rid of them efficiently by neutralizing or adsorbing the odour molecule. They are also designed for removing VOC and for meeting hazardous air pollutants along with other regulations.
For designing an efficient odour control unit, it depends on two main parameters:
● Air volume
● Air exchange
While calculating the air volume of any process tank, if it is an affixed water level tank, then freeboard air volume should be considered. But when it fluctuates, it is recommended to consider air volume from low water levels.
Air exchange is one of the essential factors to consider while designing the odour control system and one that impacts the size and effectiveness of the odour removal. Many regional municipalities have given guidance on-air exchange factors during the estimation of odour control system capacity.
While considering inlet works, the air exchange factors should be 12-15 times of the air volume. A sludge treatment facility must be 6-12 times of air volume, and it is based on room ventilation, aerated tanks, etc.
Depending on these processes, the engineers can easily assess the required sufficient capacity of the odour control unit that system manufacturers should verify. To have better clarity, you can also contact an odour control specialist. Look for the best odour control services for ideal odour control management.
