Domestic Wastewater Treatment Solutions | EcoClear Water

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

Compact MBR plant

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
Constructed wetland

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-cold area unit

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

Frequently Asked Questions

+ What's the typical footprint for an MBR system?
Our integrated MBR units are compact: for 100m³/day, only 30-40m² footprint. Buried design saves land for landscaping.
+ Can treated water be reused for irrigation?
Absolutely. Grade 1A effluent meets national standards for agricultural and landscape reuse; we can add UV/chlorine to ensure microbiological safety.
+ How is the system managed in cold regions?
For high-altitude or freezing areas, we use non-powered physicochemical synergy plus buried insulated tanks, ensuring biological activity remains active.
+ What are the maintenance requirements?
Remote monitoring reduces on-site work. MBR systems require membrane cleaning every 3-6 months. Constructed wetlands need periodic plant harvesting, very low O&M.
+ Which certifications do your products hold?
CE, ISO9001, and national environmental protection certifications. Each unit is tested for hydraulic and pollutant removal performance.
+ Can I upgrade an existing septic tank system?
Yes, we provide retrofit solutions – adding MBR or BAF/wetland polishing to upgrade effluent from septic to Grade 1B/1A standard.
+ What is the typical delivery time?
Standard skid-mounted systems: 20-30 days. Custom projects including civil works: 45-60 days.
+ Do you offer financing or leasing?
Yes, for municipal and rural centralized projects we can arrange flexible payment plans, BOT or leasing models.
