Glass-fused-steel septic tank

Glass-fiber Reinforced Plastic (GRP) septic tanks are specialized equipment made with a synthetic resin matrix and glass fiber reinforcement materials, designed for treating domestic wastewater.

Its lightweight, high strength, excellent toughness, corrosion resistance, vibrant colors, and glossy finish achieving mirror-like quality.

Glass-fiber Reinforced Plastic (GRP) septic tanks are equipment made from a synthetic resin matrix and glass fiber reinforcement materials, specifically designed for the treatment of domestic wastewater. GRP septic tanks are actively promoted composite products by the state, known for their lightweight, high strength, good toughness, corrosion resistance, vibrant colors, and glossy finish resembling a mirror. They have far surpassed similar products made from ceramics, rigid plastics, and steel, and are widely used in industries such as chemicals, petroleum, construction, textiles, aviation, navigation, transportation, electricity, metallurgy, machinery, food, papermaking, and environmental protection. GRP septic tanks are used in industrial living quarters and urban residential communities as domestic wastewater purification and treatment equipment. They temporarily store excrement, allowing for preliminary decomposition within the tank to reduce the solid content in the discharged wastewater.

1. Backfilling must meet construction specification requirements. A clean-out well (inspection well) can be constructed on the pool, which comes in two types: brick-lined wells and prefabricated reinforced concrete wells.

2. To prevent leakage in brick-lined manholes, it is required to apply a waterproof mortar coating on both the inner and outer walls of the manhole, with a thickness of 20mm (1:2 waterproof mortar, with 5% of the waterproofing agent by weight of cement), and to apply a 45-degree slope at the inside corners. For a sloping surface, the thickness should be 50mm. In the presence of groundwater, apply two coats of hot asphalt (or other waterproofing coating) to the outer wall of the manhole, followed by backfilling to the ground level specifications.

Advantages

One, Cost-Effective: The fiberglass septic tank is produced through factory, mechanization, mass production, and integrated molding processes, utilizing new technology and materials. It boasts a compact size with a large effective volume.

Two, the glass fiber reinforced septic tank has an integrated shape, is lightweight and high-strength, and is quick and easy to install.

Three, the land-saving glass-fiber reinforced plastic septic tank saves excavation area.

Four, fiberglass septic tanks have excellent sealing performance, effectively treat feces, and have anaerobic decomposition effects twice as superior to conventional 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 high-level siphon drainage, with multiple sedimentation and purification processes.

Six, the durable glass fiber reinforced septic tank is made of new material glass fiber, with resistance to aging and acid-base, and has a service life of over 50 years.

Seven: High-pressure-resistant, high-compressive strength fiberglass septic tanks with international 50 steel resin sealing, cylindrical in shape, offering several times the compressive strength compared to polygonal or square designs.

Section 8: The glass-fiber septic tanks, without post-maintenance, feature a 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 carried out. The lower part of the tank should be filled with sand and soil (height should not be less than half the diameter of the tank), and it is strictly prohibited to use construction waste as backfill material. Stones in the backfill soil should be removed, and the backfill should be compacted layer by layer, with each layer compacted to a thickness of 30mm. It is recommended to use manual compaction, and it is crucial to avoid local forceful impacts during backfilling (such as with air compactors), ensuring the surrounding backfill soil is densely packed.
