As modern wastewater treatment facilities adopt more advanced tank solutions such as sewage enamel tanks, the need for durable and compatible cover systems becomes increasingly important. Hebei Leihong Fiberglass Technology Co., Ltd. recently completed the delivery of GRP (Glass Reinforced Plastic) covers for an environmental engineering project where several enamel-coated wastewater tanks required full sealing to reduce odor emissions and improve site hygiene.
Enamel tanks, also known as glass-fused-to-steel tanks, are widely used for storing sewage, sludge, and industrial wastewater due to their chemical resistance, smooth inner walls, and fast construction. However, like all open-top tanks, they can release unpleasant gases, attract contaminants, and pose safety hazards if left uncovered. To address these issues, the project contractor selected Leihong's GRP tank covers as an ideal solution.
Key Advantages of GRP Covers on Enamel Tanks:
- Corrosion Resistance: GRP covers are ideal for aggressive environments and do not react with the gases inside sewage tanks.
- Lightweight and Easy to Install: Compared to steel covers, GRP is easier to transport and assemble, especially when working at height or on narrow walkways.
- Odor Control: The sealed fiberglass covers reduce the spread of foul odors, improving working conditions for plant staff and reducing community complaints.
- Durability: GRP materials are UV-resistant, weatherproof, and require minimal maintenance, ensuring long-term operation alongside the enamel tanks.
The covers supplied for this project featured a modular arched structure, allowing for complete surface sealing while retaining access points for inspection and maintenance. The blue color was selected for visibility and harmony with the rest of the site's infrastructure.
Real-World Application and Impact
The project site is located near a densely populated area, where odor control is not only an environmental goal but also a regulatory requirement. After the installation of GRP covers, the odor levels around the tanks were significantly reduced, and the client reported a noticeable improvement in both internal air quality and visual cleanliness.
Leihong's GRP covers are now part of the site's core odor management system, alongside piping, spray towers, and biofiltration equipment. The installation demonstrates how fiberglass components are becoming an essential part of modern wastewater treatment plant upgrades, especially when paired with advanced tank technologies like enamel systems.
