Unpleasant odors are a common challenge in wastewater treatment plants, sewage treatment plants and industrial wastewater facilities. In addition to affecting the surrounding environment, corrosive gases generated during wastewater treatment can create demanding conditions for equipment and structures.
A well-designed FRP odor control system can provide an integrated approach to odor collection, conveyance and treatment.
What Is an FRP Odor Control System?
An FRP odor control system is a combination of fiberglass reinforced plastic equipment and structures used to collect and treat odorous gases generated during wastewater treatment.
A complete system may include:
FRP wastewater tank covers
FRP odor collection ducts
FRP piping
Scrubber towers
Spray towers
Biotrickling filters
Activated carbon treatment units
FRP fans and related equipment
The exact configuration can be selected according to the odor source, treatment requirements and project conditions.

FRP Covers for Odor Collection
The first step in odor control is often to contain and collect odors at the source.
FRP covers can be installed over wastewater tanks, sewage tanks, sedimentation tanks and other odor-generating areas. The covers help enclose the tank and direct collected gases toward the treatment system.
FRP is particularly suitable for wastewater environments because of its resistance to moisture and corrosion.
Different cover designs can be manufactured according to the tank dimensions and access requirements, including fixed covers and sliding cover solutions.
Scrubber and Spray Tower
After odor is collected, the gas can be conveyed through FRP ducts to a suitable treatment unit.
FRP scrubber towers and spray towers are commonly used as part of industrial gas and odor treatment systems. Depending on the process design, a scrubbing system can help remove or reduce specific contaminants from the gas stream.
FRP construction is well suited to these applications because the equipment may be exposed to moisture and corrosive substances.
Biotrickling Filter for Biological Odor Treatment
A biotrickling filter is another important technology used in wastewater odor control.
The process uses microorganisms attached to a suitable packing material to biologically treat odor-causing compounds in the gas stream. It can be integrated into a complete odor control system for wastewater and industrial applications.
The appropriate treatment process depends on factors such as gas composition, flow rate, concentration and operating conditions.
FRP Ducts and Piping
Reliable gas conveyance is essential for a complete odor control system.
FRP ducts and pipes can be customized according to the required diameter, length, wall thickness and connection configuration. They can be used to connect wastewater tank covers with scrubbers, biotrickling filters, fans and other treatment equipment.
The corrosion resistance of FRP makes it a practical material for many wastewater and chemical environments.
One-Stop FRP Odor Control Solution
Instead of sourcing covers, ducts, towers and piping from different suppliers, customers can work with one manufacturer for a more integrated solution.
At Hebei Leihong Fiberglass Technology Co., Ltd., we provide customized FRP solutions covering design, manufacturing and supply.
Our odor control product range includes FRP covers, scrubber towers, spray towers, biotrickling filter systems, FRP ducts and piping.
We can manufacture components according to customer drawings, dimensions and project requirements.
Applications
FRP odor control systems can be used in:
Municipal wastewater treatment plants
Sewage treatment plants
Industrial wastewater treatment facilities
Chemical plants
Food processing facilities
Sludge treatment areas
Wastewater collection and treatment systems
For each project, the system configuration should be selected according to the actual odor sources and treatment requirements.
