Vertical Sewage Treatment Tank

Our vertical sewage treatment tank is a compact, high-efficiency solution engineered for decentralized wastewater purification. Designed to optimize space utilization while ensuring superior contaminant removal, this tank is ideal for small-to-medium-sized residential complexes, commercial buildings, and industrial facilities with limited installation areas. It integrates physical sedimentation, biological decomposition, and disinfection processes into a single vertical structure, delivering stable, eco-friendly wastewater treatment results that meet strict discharge standards.

Material Features

1. Constructed with high-strength glass fiber reinforced plastic (FRP) or carbon steel with anti-corrosion coating, the tank boasts exceptional resistance to acid, alkali, and chemical corrosion.
2. Lightweight yet durable, FRP models ensure easy transportation and installation, while carbon steel variants offer enhanced load-bearing capacity for heavy-duty applications.
3. The inner lining adopts a smooth, non-stick material to prevent sludge adhesion and reduce maintenance frequency.

FAQ

Q: What is the difference between vertical and horizontal sewage treatment tanks?

A: The vertical design saves 30% more space than horizontal models, making it suitable for narrow installation sites.

Q: How often does the tank require sludge cleaning?

A: Generally, sludge discharge is needed every 3–6 months, depending on wastewater inflow and contamination levels.

Q: Can the tank treat industrial wastewater with high chemical content?

A: Yes, we can customize it with enhanced chemical resistance materials and advanced filtration modules for industrial use.

Q: Is the installation complicated?

A: No, the tank comes pre-assembled, and we provide detailed installation manuals.

Q: Does the tank need electricity to operate?

A: Yes, a small aeration system requires power, but energy consumption is low (only 0.5–1 kWh per cubic meter of wastewater).

Q: What discharge standards can the tank meet?

A: It complies with national first-class discharge standards for urban sewage treatment.
