FRP Underground Integrated Sewage Treatment Equipment Mixers Automatic

FRP Underground Integrated Equipment

Product Overview

The FRP Underground Integrated Equipment is a compact, corrosion-resistant unit designed for the treatment of domestic or industrial wastewater. Made of high-strength fiberglass reinforced plastic (FRP), the equipment offers excellent durability, lightweight structure, and easy installation.
It integrates multiple processes such as sedimentation, biological treatment, filtration, and disinfection in a sealed underground structure, achieving high treatment efficiency while saving surface space and maintaining a clean environment.

Working Principle

The equipment treats wastewater through a series of integrated physical, chemical, and biological processes.

• Sedimentation Section: Removes suspended solids and large particles by gravity.

• Biological Treatment Zone: Decomposes organic pollutants using aerobic or anaerobic microorganisms.

• Filtration and Disinfection: Further purify the effluent and eliminate pathogens to meet discharge or reuse standards.
  The treated water is discharged or reused, while sludge is collected and removed periodically.

Main Components

• Inlet Chamber: Balances and distributes incoming wastewater evenly.

• Sedimentation Tank: Separates suspended solids through gravity settling.

• Biological Reaction Zone: Performs aerobic, anoxic, or anaerobic treatment.

• Filtration Unit: Removes fine particles and improves effluent clarity.

• Disinfection Chamber: Ensures compliance with discharge or reuse standards.

• FRP Tank Body: Lightweight, anti-corrosive structure with full sealing and long service life.

• Sludge Storage and Discharge System: Collects and removes settled sludge.

• Ventilation and Access Covers: Maintain system safety and allow inspection.

• Electrical Control Cabinet: Integrates control, monitoring, and automation functions.
