Corrosion Protection for Odor Control Enclosures Exposed to H2S and Treatment Chemicals
Odor control systems play a critical role in water and wastewater treatment facilities, but the enclosures that house exhaust fans and related equipment are constantly exposed to harsh operating conditions. In this case study, a municipal water authority in the upper Midwest was experiencing atmospheric corrosion on odor control enclosures caused by H2S exposure and other treatment chemicals.
To restore and protect the affected assets, Unconventional Solutions recommended an Odor Control Enclosure Repair system using proper surface preparation, a corrosion-resistant primer, and a high-performance protective coating.
This project demonstrates how the right coating system can help water and wastewater facilities extend the life of fiberglass and high carbon steel enclosures while reducing the risk of ongoing corrosion damage.
Project Overview
Application: Odor Control Enclosure Repair
Industry: Water & Wastewater
Substrate: Fiberglass / High Carbon Steel
Completion Date: October 2025
Products Used: Resichem 506 Aluprime and Resichem 555 Resinox
The Problem: Atmospheric Corrosion from H2S Exposure
The municipal water authority had odor control enclosures housing exhaust fans that were suffering from atmospheric corrosion. In water and wastewater environments, hydrogen sulfide, commonly known as H2S, and other treatment chemicals can create aggressive conditions that attack metal, fiberglass, fasteners, seams, and coated surfaces.
Left unaddressed, corrosion on odor control enclosures can lead to:
- Premature equipment deterioration
- Coating failure
- Structural damage to enclosure panels
- Higher maintenance costs
- Reduced service life of exhaust fan housings
- Increased risk of downtime or emergency repairs
For this facility, an Odor Control Enclosure Repair was needed to clean, prepare, and protect the affected surfaces before corrosion could continue spreading.
The Solution: Hydroblasting, Primer, and Protective Coating
Unconventional Solutions inspected the affected odor control enclosures and recommended a coating system designed to protect against harsh wastewater treatment conditions.
The repair process started with hydroblasting at 3,000–5,500 PSI to remove dirt, oils, grime, and loose debris from the surface. This step helped prepare the fiberglass and high carbon steel substrates for coating adhesion.
After surface preparation, a primer coat of Resichem 506 Aluprime was applied. The system was then finished with two coats of Resichem 555 Resinox at 16 mil wet film thickness.
The completed Odor Control Enclosure Repair helped restore a clean, protected surface and improve long-term corrosion resistance in a demanding water and wastewater environment.
Benefits of Odor Control Enclosure Repair
A properly specified Odor Control Enclosure Repair system can provide several advantages for municipal and industrial wastewater facilities.
Key benefits include:
- Protects enclosures exposed to H2S and treatment chemicals
- Helps stop ongoing atmospheric corrosion
- Extends the service life of odor control equipment
- Restores the appearance of corroded enclosure surfaces
- Reduces the need for costly replacement
- Supports long-term asset protection in wastewater environments
- Improves corrosion resistance on fiberglass and high carbon steel substrates
- Helps protect exhaust fan housings and odor control system components
Why Odor Control Enclosures Need Corrosion Protection
Odor control systems are often installed in areas where chemical exposure, moisture, and airborne contaminants are unavoidable. These conditions can accelerate corrosion, especially when H2S and wastewater treatment chemicals are present.
Instead of waiting for corrosion to cause structural deterioration or equipment failure, facilities can use an Odor Control Enclosure Repair system to restore damaged surfaces and add long-term protective coating performance.
For municipal water authorities, wastewater treatment plants, and industrial facilities, this type of repair can be a practical alternative to replacing enclosure panels, fan housings, or other exposed components.
