With ISO9001 certification, our production process follows strict quality control measures, guaranteeing consistent product quality and reliability.
Key Features and Benefits:
Superior Corrosion Resistance – Fiberglass material resists acids, alkalis, and chemicals, making it ideal for aggressive sewage environments. No rust or degradation over time.
Lightweight & High Strength – Only 1/4 the weight of concrete tanks, yet offers comparable structural integrity. Easy to handle and install without heavy machinery.
Excellent Sealing Performance – One-piece molded construction with no seams or joints prevents leakage, ensuring safe containment of biogas and wastewater.
Long Service Life – Designed for over 30 years of operation with minimal maintenance. UV-resistant coating protects against sun damage for above-ground installations.
Customizable Capacity & Configurations – Available in sizes from 1,000L to 50,000L, with options for inlet/outlet positions, manholes, and biogas outlet connections.
Efficient Anaerobic Digestion – Smooth inner surface reduces sludge accumulation and promotes biogas production. Optimized volume-to-surface ratio for stable microbial activity.
Eco-Friendly & Sustainable – Supports renewable energy generation by capturing biogas (methane) for cooking, heating, or electricity. Reduces greenhouse gas emissions from untreated sewage.
ISO9001 Certified Quality – Manufactured under strict quality management systems, ensuring each tank meets international standards for strength, durability, and safety.

Frequently Asked Questions (FAQ)
Q: What is the difference between FRP and GRP?
A: FRP (Fiberglass Reinforced Plastic) and GRP (Glass Reinforced Plastic) are essentially the same material. Both refer to a composite of glass fibers and resin. The terms are used interchangeably in the industry.Q: Can this tank be used for both biogas and sewage treatment?
A: Yes, our tank is specifically designed for anaerobic digestion of sewage to produce biogas while simultaneously treating wastewater. The sealed environment promotes methane generation and reduces pollution.Q: What is the typical lifespan of the tank?
A: With proper installation and maintenance, the expected service life exceeds 30 years. The material is resistant to corrosion, UV rays, and soil chemicals, ensuring long-term durability.Q: Do you offer custom sizes or configurations?
A: Absolutely. We can customize the tank capacity, dimensions, inlet/outlet positions, number of chambers, and biogas outlet fittings according to your project needs. Minimum order quantity may apply.Q: How is the tank installed?
A: The tank can be installed either underground or above ground. For underground installation, we recommend a concrete base and proper backfill. Detailed installation instructions are provided with each order.Q: Is the tank safe for biogas storage?
A: Yes, the tank is designed to be gas-tight. All joints and connections are sealed to prevent biogas leakage. The material is also resistant to the acidic environment inside the tank.Q: What is the lead time for an order?
A: Lead time depends on the quantity and customization. Typically, standard tanks are delivered within 15–20 working days after order confirmation. Custom orders may take 25–40 days.Q: Do you provide after-sales technical support?
A: Yes, our team offers online technical support for installation, operation, and maintenance. We also provide a one-year warranty against manufacturing defects.
