FRP Arch Covers For Wastewater Treatment: Durable GRP Cover Solutions For Odor Control

Aug 18, 2026 Leave a message

FRP Arch Covers

In modern wastewater treatment plants, effective tank covering is becoming increasingly important for odor control, environmental protection, and long-term facility operation. FRP covers, also known as GRP covers, provide a lightweight, corrosion-resistant solution for covering wastewater tanks, sedimentation tanks, sludge tanks, and other treatment structures.

Hebei Leihong Fiberglass Technology Co., Ltd. manufactures customized FRP arch covers and GRP covers for wastewater treatment and industrial applications.

What Is an FRP Arch Cover?

An FRP arch cover is a fiberglass reinforced plastic cover designed with an arched structure. The curved design provides a practical solution for covering large circular or rectangular tanks while creating an enclosed space above the wastewater.

Unlike conventional flat covers, self-supporting FRP dome and arch covers can be designed according to the dimensions and layout of the tank.

FRP arch covers are commonly used for:

Wastewater treatment tanks

Sedimentation tanks

Clarifiers

Sludge tanks

Anaerobic and fermentation tanks

Sewage collection tanks

Industrial process tanks

Odor control facilities

FRP Covers for Wastewater Odor Control

One of the main applications of GRP covers is wastewater odor containment.

Wastewater treatment processes can generate unpleasant gases and odors. Leaving treatment tanks open can allow these odors to spread into the surrounding environment.

By installing an FRP tank cover, the treatment area can be enclosed and the collected gases can then be directed to an odor control system, such as a scrubber tower, spray tower, biofilter, or biotrickling filter.

This creates an integrated solution:

FRP Cover → Odor Collection → FRP Duct → Odor Control System

The FRP cover therefore becomes an important part of the overall wastewater odor control system.

Why Choose FRP / GRP Covers?

FRP and GRP are widely used in wastewater and industrial environments because of their resistance to moisture and corrosion.

1. Excellent Corrosion Resistance

Wastewater treatment environments can contain moisture, chemicals, and corrosive gases. FRP provides a suitable material option for these demanding conditions.

2. Lightweight Construction

Compared with many traditional construction materials, fiberglass reinforced plastic covers are lightweight, making transportation, handling, and installation more convenient.

3. Customized Design

Every wastewater treatment project is different. Our FRP covers can be customized according to tank diameter, length, width, support conditions, access requirements, and other project specifications.

4. Weather Resistance

For outdoor wastewater tanks, the cover is exposed to sunlight, rain, wind, and changing weather conditions. FRP covers can be manufactured with a suitable surface finish and UV-resistant gelcoat for outdoor applications.

5. Low Maintenance

FRP does not rust like conventional steel materials. Combined with its corrosion resistance and weather-resistant surface, this can help reduce maintenance requirements during long-term operation.

FRP Arch Covers for Circular Tanks

Circular tanks are widely used in wastewater treatment and industrial processes. Our FRP arch covers for circular tanks can be manufactured according to the tank diameter and project requirements.

The arch structure provides a practical covering solution while leaving space for odor collection and other equipment.

Circular FRP covers are suitable for:

Clarification Tanks | Sedimentation Tanks | Fermentation Tanks | Sludge Tanks | Wastewater Tanks

For projects requiring odor containment, openings and connections can also be incorporated according to the customer's requirements.

FRP Covers for Sedimentation Tanks

Sedimentation tanks and clarifiers are common applications for GRP covers.

A properly designed cover can help isolate the treatment process from the surrounding environment while providing a suitable connection point for odor extraction.

For large wastewater treatment projects, FRP covers can be combined with FRP structural profiles, FRP walkways, handrails, ducts, and odor control equipment to create a complete composite solution.

UV-Resistant FRP Cover Surface

Outdoor wastewater covers are continuously exposed to sunlight. For this reason, the surface finish is an important consideration.

Our FRP covers can be produced with a UV-resistant gelcoat surface to improve outdoor weather resistance and color retention. Depending on the selected materials and actual environmental conditions, the surface can provide long-term outdoor performance.

This makes FRP a practical choice for wastewater treatment facilities where the cover will remain outdoors for many years.
