Proper ventilation is required for the following purposes:
Materials Suitable for Wastewater Ventilation Equipment
Due to the corrosive contaminants being emitted, there are only few reliable materials that can be used wastewater treatment municipalities.
As mentioned before, the material makeup of the equipment will depend on the process being performed and the byproducts associated with it.
Fiberglass is the most common material used due to its durability, reliability and versatility. Available in centrifugal, radial and axial configurations it is truly the most versatile and reliable solution for wastewater applications.
Types of Ventilation in Wastewater Treatment Plants
Proper ventilation in wastewater treatment and reclamation facilities includes both exhaust and make-up air. Based on the various steps in the process, this can come in many forms.
The most common ventilation solution is mechanical exhaust and mechanical intake, often referred to as push / pull. A mechanical ventilation system provides a controlled solution allowing air being introduced and exhausted to be directed per a plan that includes both a designated flow rate and direction.
When heat, gases and pollutants are produced faster than the flow rate of atmospheric or fresh air, then mechanical industrial ventilation equipment is essential.
Another common ventilation practice power / gravity solution. This consists of one part of the ventilation system being powered while the other is natural or gravity fed.
For example, within a space requiring the removal of process heat oftentimes a powered exhaust fan will be installed on the roof while a series of wall louvers are installed in the walls below. The negative pressure generated by the exhaust fan will pull the makeup air required through the louvers as they are the path of least resistance to balance the building pressure.
This method can also be performed conversely with the air being powered into the space and pushed out through a louver or gravity vent. This method is typically used for heat removal and not recommended for gas, pollutant or odor removal.
Wastewater Treatment Blowers
Air blowers for wastewater treatment facilities are the most common type of mechanical air equipment used. Blower fans assist in treating sewage odors and other byproducts that emanate from the facility. These mechanical fans are also made of anti-corrosive materials, which help extend the life of the blower fan in the wastewater treatment plant.
Wastewater treatment plants must prioritize odor control, especially in urban and residential zones. These facilities produce hydrogen sulfide (H2S) gas which is highly toxic and has an equally offensive smell (sciencedirect.com source). This gas is typically the main cause of unpleasant odors in and around a wastewater reclamation facility.
Fortunately, there are many reliable options for facilities in which they can reduce or completely eradicate odor emissions safely and efficiently. The combination of a fume scrubber, blower fans, and the corresponding fiberglass exhaust fan will do the trick.
When designing, replacing, upgrading or implementing anything in a water treatment plant there are regulations that must be adhered to. Whether those regulations are for odors, electric efficiency, or any of the many other regulatory compliance issues, choose a supplier with expertise with such regulations.
