Compact Sewage Treatment Plant China Factory

Compact Sewage Treatment Plant

Introduction
For decentralized wastewater management, Hebei Huayu Environmental Engineering Co., Ltd offers compact sewage treatment plants that combine biological and physical processes in a small footprint. These plants serve rural communities, resorts, schools, and small residential developments where municipal sewers are unavailable or impractical.

Process Sequence

1. Primary Settlement

• Inlet Chamber: Removes coarse solids and floating debris through screening and grit separation.

• Settling Tank: Promotes gravity separation of settleable solids.

2. Biological Treatment

• Sequencing Batch Reactor (SBR): Operates in fill, react, settle, draw, and idle phases, providing flexibility for load variations.

• Moving Bed Biofilm Reactor (MBBR): Contains suspended carriers that support biofilm growth, enabling continuous aeration and treatment.

3. Secondary Clarification

• Settling Chamber: Returns biomass to the reactor and discharges clarified effluent.

4. Tertiary Polishing (Optional)

• Sand or Membrane Filtration: Further reduces solids and turbidity.

• Disinfection: UV or chlorination modules for pathogen reduction.

Key Features

• Compact Footprint: Skid-mounted or sectional prefabrication enables installation on tight sites.

• Low Power Demand: Energy-efficient blowers and variable-frequency drives reduce operational costs.

• Automated Operation: Programmable control of fill and aeration cycles adapts to varying influent characteristics.

• Odor Control: Sealed tanks and activated-carbon vent filters mitigate nuisance smells.

Materials and Assembly
Reactor and clarifier modules use FRP or coated carbon-steel for durability. Internals—including diffusers, mixers, and baffles—are accessible through manways for maintenance. Mechanical and electrical components are housed in weatherproof cabinets.

Applications
Ideal for remote lodges, construction camps, remote schools, and small apartment complexes, these plants provide effluent quality suitable for irrigation, landscape watering, or controlled discharge to local water bodies.

Maintenance
Hebei Huayu’s service packages cover sludge removal, diffuser cleaning, sensor calibration, and inspection of moving parts. Scheduled preventive-maintenance visits help maintain performance and regulatory compliance.
