Domestic Wastewater Treatment Solutions
Domestic sewage – from rural villages, scenic spots, and unsewered areas – requires efficient, decentralized treatment. Our integrated and modular solutions eliminate water pollution, reduce footprint, and enable water reuse for agriculture and landscaping. Tailored technologies from A²/O-MBR to constructed wetlands meet Grade 1A standards.
Technology & Application Routes

Decentralized / Small-scale
- A²/O-MBR membrane process: simultaneous COD, NH₃-N, TN & TP removal
- Integrated pre-treatment, bio-reactor, ultrafiltration & disinfection
- Compact footprint, ideal for villages, resorts & service areas
- Intelligent aeration & remote monitoring module
- Effluent ready for direct reuse or safe discharge

Rural Areas with Land Resources
- Biological aerated filter (BAF) + constructed wetland combination
- Eco-friendly synergy of soil, plants & microorganisms
- Low-cost natural polishing, minimal energy demand
- Ideal for decentralized villages & agricultural communities
- Enhanced biodiversity & landscape integration

High-Altitude / Water-Scarce Regions
- Non-powered physicochemical synergy + anaerobic fermentation
- Vacuum collection & low-temperature resistant design
- Stable operation even under freezing conditions
- Resource recovery: biogas & soil conditioner
- Minimal maintenance and zero energy consumption options
Core Advantages & Equipment
Integrated Modular Design
Buried/above-ground plants – carbon steel epoxy or stainless steel. Prefabricated MBR, intelligent blowers, UV/chlorine disinfection.
High Treatment Performance
Grade 1A effluent (COD≤50mg/L, NH₃-N≤5mg/L). Reuse for irrigation, landscaping, or industrial cooling.
Smart O&M
Remote monitoring & predictive maintenance. Energy efficiency up to 20% lower than conventional plants.
Process & Equipment Configuration
Small / Medium decentralized treatment (A²/O-MBR)
- Process flow: Pre-treatment → Anoxic/Anaerobic/Oxic → MBR membrane → UV disinfection
- Core equipment: Integrated buried unit, MBR cassette, intelligent aeration, backwash system, remote control
- Benefits: Excellent nitrogen/phosphorus removal, low sludge yield, small footprint, fully automatic
- Typical capacity: 5 – 500 m³/day, perfect for residential clusters, hotels, highway stops
BAF + Constructed Wetland (Low-cost ecological)
- Process: BAF pre-treatment → subsurface flow wetland → polishing pond
- Equipment: BAF reactor, distribution system, wetland media & aquatic plants
- Advantages: Almost zero energy, natural oxygenation, habitat creation
- Suitability: Villages with available land, seasonal tourist areas, remote communities
High-Cold / Arid Regions (Non-powered synergy)
- Technology: Anaerobic baffled reactor + physicochemical filtration + passive aeration
- Core units: Vacuum collection system (optional), subsurface infiltration bed, anaerobic digester
- Performance: Freeze-resistant operation, pathogen reduction, biogas recovery for cooking
- Ideal for: Tibetan plateau, northern rural areas, water-deficient provinces
Proven Results & Case Example
Compliance & Reuse Standards
Effluent consistently meets GB18918-2002 Grade 1A / 1B (COD ≤50 mg/L, NH₃-N ≤5-8 mg/L). Treated water is safely reused for farmland irrigation, green space watering, or surface water discharge.
Yanghe Town, Anyang County Project
Capacity: 1,000 m³/day · Serves multiple villages · Technology: A²/O + MBR + UV disinfection. The plant has been operating for 3+ years with stable Grade 1A effluent, supplying irrigation water for surrounding farmland. Remote monitoring reduced on-site labour by 70% and energy cost by 18% compared to conventional SBR.
✓ SS reduction from 200mg/L to <5mg/L · NH₃-N removal >96% · zero odor complaints
Customer Feedback
"We operate 4 beach resorts across Palawan and needed reliable wastewater treatment without spoiling our landscapes. Their 200 m³/day integrated MBR systems were installed in just 3 weeks — now we reuse every drop for our tropical gardens. After 2 years of continuous operation, zero downtime and remote monitoring means our maintenance team handles everything from a tablet."

"As County Environmental Officer, I evaluated five international suppliers before choosing this solution for our 12 rural villages in Kiambu. The BAF + constructed wetland hybrid system treats 800 m³/day with almost zero electricity — our communities now have clean water and the wetlands attract birds we haven't seen in years. Maintenance? We just harvest the reeds twice a year. The county government is now funding expansion to three more districts based on our results."

"We needed wastewater treatment for 5 desert eco-lodges in Wadi Rum where temperatures swing from -5°C to 45°C and grid power is non-existent. Their non-powered anaerobic treatment system was custom-engineered for our conditions — it's been running 18 months straight through freezing nights and scorching days with zero energy input. Our guests don't even know it's there. We're now planning to specify the same system for our new Red Sea camp development."
