What is the Capacity of Odour Control systems in WWTP?
Maximum airflow volume measured in m3/hr. (cubic meters per hour) is processed by odour control systems. This measurement is estimated depending on the plant or operational site's capacity.
But, why is the capacity measured in m3/hr.?
Simply said, m3/hr is the amount of air that the odour control systems will treat in an hour. A higher m3/hr indicates a greater capability. However, more capacity is not always desired, particularly in smaller systems, because greater capacity implies a larger, more sophisticated system, which raises expense. As a result, striking a balance between capacity and size is critical.A basic odour control device has a capacity ranging from 50 m3/hrto 1,000 m3/hr, which appears to be rather large.
An odour control system's capacity to treat airflow volumes is determined by four important factors:
• System dimensions;
• Choosing an adsorbent;
• Adsorption ability;
• Process parameters – temperature, chemical components, and moisture.
There is more to meeting a necessary m3/hr.range than pumping a large amount of air through a complex system, i.e., the odour control system must successfully treat the air and reach the target odour concentration.
How is odour estimated in wastewater treatment plants?
Consider the free board air volume for estimating the air volume of process tanks with a constant water level. If the tank has a variable water level, utilize the air volume from the minimum liquid level.Air exchange parameters are particularly important in developing the odour control system capacity, which influences the size and efficiency of smell elimination. The majority of regional Governments have issued explicit instructions on the air exchange parameters to be considered when determining odour control system capacity.
Typically, air exchange coefficients of 12-15 of the volume of the air are considered for inlet works.And it will be 6-12 of the volume of air in the sludge treatment plant, depending on the ventilated room, aerated tanks, and so on.Based on this, a process engineer may determine the preliminary capacity of an odour control system, which can then be validated by genuine odour control system manufacturers.
