When designing effective odour control systems, accurately estimating the air volume within process tanks is crucial. This process varies significantly depending on whether the tank operates at a fixed or fluctuating water level.
Fixed Water Level Tanks
For fixed water level tanks, the concept of freeboard air volume comes into play. Freeboard is the space above the water level, and this volume must be accounted for when calculating the total air volume. This ensures that the odour control system can manage the gaseous emissions effectively, as the air space above the liquid directly impacts odour concentration.
Fluctuating Water Level Tanks
In contrast, if the tank experiences fluctuations in water level, it’s advisable to consider the air volume at the lowest water level. This approach guarantees that the system is adequately designed to handle potential peaks in odour release, providing a buffer against variations in water levels.
The distinction between these two scenarios is critical for ensuring that odour control systems are not only effective but also efficient in their operation.
The Importance of Air Exchange Factors
Air exchange factors play a pivotal role in the design and functionality of odour control systems. These factors influence the size, capacity, and overall efficiency of the system. In many regions, municipalities have established guidelines regarding the air exchange rates that should be considered when estimating the capacity of odour control systems.
Typically, for inlet works, the air exchange factor is often set between 12 and 15 times the volume of air in the system. This means that for every unit of air volume in the tank, 12 to 15 units of air should be exchanged per hour to effectively mitigate odours.
For sludge treatment facilities, the air exchange factor generally ranges from 6 to 12. This variation depends on several factors, including the design of the ventilated room, the characteristics of the aerated tanks, and the specific odour challenges faced by the facility.
Calculating Preliminary Capacity
Based on these air exchange factors, process engineers can derive a preliminary capacity for the odour control system. This initial estimate serves as a foundation for designing a system that meets operational needs while adhering to regulatory standards.
However, it’s essential for engineers to verify these preliminary calculations with established odour control system manufacturers. Collaboration with manufacturers ensures that the system’s design aligns with industry best practices and technological advancements.
