Water Treatment Plant Blowers
Proper ventilation equipment in wastewater treatment and reclamation facilities includes both exhaust and blower fans. Make up air units are also implemented in some cases. Based on the various steps in the process, this can come in many forms.
- Gravity Exhaust (Ridge Vents, Gravity Roof Vents, Louvers)
- Gravity Intake (Penthouses, Louvers, Intake Hoods)
- Mechanical / Powered Exhaust (Fans, Blowers)
- Mechanical / Powered Intake (Fans, Blowers, Makeup Air Units)

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, gasses and pollutants are produced faster than the flow rate of atmospheric or fresh air, then mechanical industrial ventilation equipment is essential.
Another ventilation solution is gravity ventilation. This consists of one part of the ventilation system being powered while the other is natural ventilation or gravity fed.
Wastewater Treatment Blowers
Wastewater treatment blowers and aeration fans 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.
Materials Suitable for Wastewater Ventilation Equipment
Due to the corrosive contaminants being emitted, there are only few reliable materials that can be used in wastewater treatment municipalities.
- Fiberglass
- PVC (Polyvinyl Chloride)
- Polypropylene
- Carbon Steel with coating
- Aluminum
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.

Wastewater Facilities Ventilation Challenges
Wastewater treatment and reclamation facilities provide the single largest pollution control effort on earth.
Generating water that is clean enough to be returned to the streams, rivers and lakes from which it came. The water is being returned to the world and the people within it, therefore it is paramount that the system cleaning the water be beyond reproach.
To achieve this high level of reliability the system should comprise of equipment that is equally reliable.
The process of wastewater treatment produces many byproducts requiring ventilation, such as heat, moisture, fumes and odors. Each of these byproducts can also include corrosives that have a harmful effect on people, structure and process.
For this reason it is important to utilize the appropriate industrial ventilation equipment for the job.
Applying the right ventilation equipment in a wastewater treatment plant will ensure a reliable and long lasting process.
From air blowers for wastewater treatment facilities to makeup air, we will provide equipment that checks all the boxes.
Fans that are suitable for heavy duty, corrosive duty, and moisture laden applications. Our ventilation equipment will provide a reliable solution to maintain a quiet and clean environment for the site and surrounding community.
Chemical corrosion is a common challenge within a wastewater treatment plant or similar municipal water facility. The harsh chemicals supporting the non-stop operation of sludge-drying, odor controls, air strippers, aeration tanks and other essential equipment necessary for the wastewater reclamation process.
- Hydrogenation may occur when a metal is immersed in non-aerated water or non-oxidizing acid.
- Common treatment chemicals such as chlorine, various acids and alkalis and ferric chloride are corrosive.
- Hydrogen Sulfide (H2S) gas can directly attack metallic components (i.e. steel tanks, gratings and walkways, structural members and equipment).
Proper ventilation is required for the following purposes:
- Providing a positive indoor air quality (IAQ) for employees to work safely in clean, fresh air.
- Purging emitted pollutants from plant spaces to protect the structures & equipment.
- Managing the air introduced and expelled from plant spaces to ensure a clean environment in and around the plant.
- Odor control
- Temperature control (cooling, heating)
- Expelling heat that is produced by the equipment, such as generators, motors, blowers, and other heavy water treatment equipment.
- Dispel humidity in order to eradicate the chance of condensation, which is the root cause of corrosion and the development of contaminants.
- Dispel smoke in the event of a fire
Odor Control
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, such as wastewater treatment blowers, 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.
Zoning Regulations
When designing, replacing, upgrading or implementing equipment such as wastewater treatment blowers, 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.
Budgets
