Wastewater Treatment Tank

Sewage treatment storage tanks are specialized equipment within wastewater treatment systems designed for storing, settling, reacting, or temporarily holding sewage. Featuring corrosion resistance, reliable sealing, and adaptability to varying water qualities, they serve as core facilities in municipal sewage and industrial wastewater treatment projects.

• Fiber-Reinforced Plastic (FRP): Exceptional corrosion resistance, lightweight yet high-strength, suitable for acidic/alkaline wastewater and heavy metal-containing effluents. Widely adopted.
• Carbon Steel + Anti-Corrosion Coating: Moderate cost with epoxy or polyurethane coatings on inner walls, suitable for neutral or mildly corrosive wastewater.
• Stainless Steel (304/316L): Superior corrosion resistance and easy cleaning, ideal for high-quality water requirements or highly corrosive conditions (e.g., chemical wastewater).
• Concrete: Suitable for sedimentation tanks and equalization tanks in large municipal wastewater treatment plants. Offers high capacity and stability but requires a longer construction period.

• Strong Corrosion and Fouling Resistance: Materials and anti-corrosion designs are specifically matched to different wastewater characteristics, withstanding organic corrosion from domestic sewage, acid/alkali corrosion from industrial wastewater, and salt corrosion from high-salinity wastewater to prevent tank damage and sewage leakage.
• Versatile Functionality: Can serve multiple roles based on treatment processes, including: - Equalization tanks (balancing wastewater flow and quality) - Sedimentation tanks (separating suspended solids) - Reaction tanks (dosing chemicals for acid-base neutralization or redox reactions) - Sludge storage tanks (holding concentrated sludge)
• Flexible Capacity Specifications: Customizable volumes ranging from tens of cubic meters (small-scale industrial wastewater treatment) to tens of thousands of cubic meters (municipal sewage plants). Supports single-tank or multi-tank cluster configurations to accommodate varying treatment capacities.
• Superior Sealing and Environmental Performance: Sealed structural design prevents wastewater odor dispersion and harmful gas emissions, eliminating secondary pollution. Some tanks feature covers or breather valves to meet environmental discharge requirements.
• Application Scenarios: Widely used in municipal wastewater treatment plants, industrial parks (chemical, pharmaceutical, dyeing, electroplating, food processing, etc.), medical institutions, aquaculture facilities, mines, and more. Suitable for wastewater pretreatment (equalization, sedimentation), advanced treatment (reaction, filtration), sludge storage and transfer, or as emergency tanks for handling sudden wastewater surges.
