What is Municipal Sewage Treatment?
Municipal sewage treatment is the systematic process of removing contaminants from domestic, commercial, and urban wastewater to produce clean effluent safe for environmental discharge or water reuse, protecting public health, aquatic ecosystems, and water resource sustainability.
As urbanization accelerates globally, Municipal Wastewater Treatment Project has become essential infrastructure, and choosing a professional Municipal Sewage Treatment Project EPC Contractor is critical to stable, efficient, and long-life operation. Center Enamel, with advanced anaerobic technologies, high-performance GFS Tanks, and full-cycle EPC capabilities, provides reliable, low-carbon, and cost-effective solutions for municipal sewage treatment worldwide.
What is Municipal Sewage?
Municipal sewage mainly consists of domestic wastewater, commercial and catering drainage, public institution sewage, and a small portion of urban stormwater runoff. It contains high concentrations of organic matter, nitrogen, phosphorus, suspended solids (SS), pathogens, oils, and detergents. Direct discharge causes eutrophication, black and odorous water, pathogen spread, and severe damage to rivers, lakes, and coastal environments. Therefore, standardized collection and treatment are essential for urban ecological safety.
Core Objectives of Municipal Sewage Treatment
- Remove organic pollutants (COD, BOD₅) to prevent oxygen depletion in water bodies.
- Reduce nitrogen and phosphorus to control algal blooms.
- Eliminate suspended solids and sludge to avoid pipeline blockage and sediment accumulation.
- Kill pathogenic microorganisms to protect public health.
- Recycle water and energy to support low-carbon and circular-economy development.
Key Anaerobic Technologies Used in Municipal Sewage Treatment
Anaerobic treatment is widely applied in Municipal Wastewater Treatment Project due to low energy consumption, high organic removal efficiency, and biogas recovery capability. Center Enamel integrates four mature, high-efficiency anaerobic processes to meet different scales, water qualities, and site conditions.
1. IC (Internal Circulation) Process
IC is a high-rate anaerobic reactor with two-stage reaction and biogas-driven internal circulation, strengthening mass transfer and improving load capacity by 3–5 times over traditional reactors. It features a small footprint and high COD removal, ideal for large-scale, land-scarce municipal plants.
2. CSTR (Completely Stirred Tank Reactor) Process
CSTR uses mechanical stirring to achieve full mixing, avoiding sediment and scum formation. It has strong adaptability to high-SS and complex municipal sewage, ensuring stable operation and continuous biogas production, suitable for centralized treatment plants and zero-waste systems.
3. UASB (Upflow Anaerobic Sludge Blanket) Process
UASB relies on a dense granular sludge blanket; wastewater flows upward for full contact and degradation. With high efficiency, stable performance, and low investment, it is widely used in global municipal and industrial wastewater projects, especially for liquid-phase sewage treatment.
4. USR (Upflow Solid Reactor) Process
USR integrates concentration, reaction, and sedimentation with a simple structure and low energy consumption. It is compact, easy to operate, and cost-effective, suitable for small-to-medium municipal plants, town projects, and renovation sites.
Core Equipment Provided by Center Enamel
Center Enamel supplies a complete equipment package for Municipal Wastewater Treatment Project, with GFS Tanks as the flagship core equipment.
GFS Tanks (Glass-Fused-to-Steel Tanks)
GFS Tanks are manufactured by fusing high-quality enamel to special steel plates at over 820℃, forming a durable, inert composite structure.
Extreme corrosion resistance: Stable in pH 1–14, resisting acid, alkali, salt, and organic corrosion, with a service life of over 30 years.
Excellent structural stability: Bolted modular design provides superior seismic and UV resistance, adapting to diverse climates.
Fast installation: Factory prefabricated and bolt-assembled on site, no welding or long curing period, shortening construction time.
High customization: Flexible volume and specification for anaerobic reactors, equalization tanks, storage tanks, and sludge tanks.
Fusion Bonded Epoxy (FBE) Tanks
Used for equalization, treated water storage, and non-anaerobic sections, with cost-effective, uniform, and durable coating.
Biogas & Odor Control Equipment
Double-membrane gas holders safely collect biogas for power generation or heating; aluminum dome roofs resist corrosion, control odor, and prevent rainwater dilution.
Supporting Process Equipment
Grilles, pumps, mixing systems, aeration systems, and automatic monitoring ensure stable full-process operation.
