Glass-fiber Reinforced Plastic (GRP) septic tanks are specialized equipment made with a synthetic resin matrix and glass fiber reinforcement materials, designed for the treatment of domestic wastewater.
Its lightweight, high strength, excellent toughness, corrosion resistance, vibrant colors, and mirror-like finish.
Fiberglass septic tanks are specialized equipment made from a synthetic resin matrix and reinforced with glass fiber materials, designed for the treatment of domestic wastewater. These tanks are actively promoted by the state as composite material products, offering advantages such as lightweight, high strength, excellent toughness, corrosion resistance, vibrant colors, and a glossy finish that resembles a mirror. They have far outperformed similar products made from ceramics, rigid plastics, and steel, and are widely used in industries such as chemicals, oil, construction, textiles, aviation, maritime, transportation, electricity, metallurgy, machinery, food, papermaking, and environmental protection. Fiberglass septic tanks are also used in industrial and civil buildings, such as industrial enterprises' living areas and urban residential communities, for the purification and treatment of domestic wastewater. These tanks temporarily store excrement, allowing for initial decomposition within the tank to reduce the solid content in the discharged wastewater.
1. Backfilling must meet construction specification requirements, allowing for the construction of clean-out wells (inspection wells) on the pool. There are two types of clean-out wells: brick-lined wells and prefabricated reinforced concrete wells.
2. To prevent leakage in the brick-lined well walls, it is required to apply a waterproof mortar coating on the inner and outer walls of the well, 20mm thick (1:2 waterproof mortar with 5% of the waterproofing agent by weight of the cement), and to slope the corners at 45 degrees. For inclined surfaces, the thickness should be 50mm. When there is groundwater, apply two layers of hot asphalt (or other waterproof coating) to the outer wall of the well, and then cover it with soil to the ground level requirements.
Advantages
One, Cost-effective: Fiberglass septic tanks are produced through factory-based, mechanized, mass production, and integrated molding processes, utilizing new technologies and materials. They have a small footprint with a large effective volume.
Section 2: The integrated glass fiber septic tank design is lightweight, high-strength, and quick and easy to install.
Three, the compact glass fiber septic tank saves land excavation area.
Four, fiberglass septic tanks have excellent sealing performance, effectively treating feces with anaerobic decomposition that is over twice as effective as traditional septic tanks.
Five, the environmentally-friendly glass fiber reinforced plastic septic tanks are produced in one piece, offering excellent sealing performance with no leakage or contamination of surface water. They do not corrode the surrounding plants, grass, trees, or electrical cables. The tanks utilize a high-level siphon drainage system with multiple sedimentation and purification processes.
Section 6: Durable glass fiber reinforced plastic septic tanks are made of new material glass fiber, with resistance to aging, acids, and alkalis, and have a lifespan of over 50 years.
Section 7: High-pressure-resistant GRP septic tanks with international 50 steel resin sealing, cylindrical shape, offering several times the compressive strength compared to polygonal or square designs.
Section 8: The glass-fiber septic tanks with no post-maintenance and long slag removal cycle are buried underground, require no power, and no maintenance or management is needed in the later stage.
Once the glass-fiber reinforced concrete septic tank is in place, backfilling should be done, with the lower part of the tank surrounded by compacted sand and soil (height not less than half the diameter of the tank). It is strictly prohibited to use construction waste as backfill soil. Stones in the backfill soil should be removed, and the backfill should be compacted layer by layer, with each layer compacted at a thickness of 30mm. It is advisable to use manual compaction. Avoid local violent impacts during backfilling (such as using air rammers), ensuring the surrounding backfill soil is compacted uniformly.
