Compact Sewage Treatment Plant
For communities, resorts, and small industrial facilities requiring decentralized sanitation solutions, Hebei Huayu Environmental Engineering Co., Ltd supplies compact sewage treatment plants that effectively treat domestic and light-industrial wastewater in a small footprint.
Process Flow
– Primary Treatment: A small inlet chamber removes coarse solids and grit.
– Biological Reactor: A compact MBBR or SBR module degrades organic load with attached-growth biomass, achieving BOD₅ removal above 85%.
– Secondary Clarification: Settles biomass, returning a portion as return activated sludge (RAS) and discharging effluent.
– Tertiary Treatment: Optional sand or membrane filtration and UV disinfection deliver effluent suitable for irrigation or nonpotable reuse.
Key Features
– Modular Skid: Factory-assembled units arrive ready for connection to local sewerage and power.
– Energy Efficiency: Low-energy blowers and submersible pumps minimize operational costs.
– Low Odor Design: Sealed tanks and vent scrubbers reduce nuisance odors.
Materials and Construction
Tank modules are constructed of FRP or pre-cast concrete with internal coatings resistant to sulfide corrosion. All mechanical equipment is selected for continuous submersion service where applicable.
Use Cases and Support
Ideal for rural villages, remote lodges, and small campuses, these compact plants provide reliable treatment without reliance on large municipal infrastructure. Hebei Huayu Environmental Engineering Co., Ltd offers site customization, commissioning, and long-term service agreements to maintain performance and regulatory compliance.
