Municipal Wastewater Treatment Solution
Longdai’s solutions for municipal and decentralized wastewater treatment projects are designed around each project's treatment scale, influent quality, effluent standard, site conditions, and reuse needs which run from process design and equipment configuration to installation and commissioning. Treatment capacities range from 10 to 50,000 m³/d. Process selection and system configuration follow the actual project conditions, and we supply standalone equipment, complete process packages, and EPC engineering services. The equipment scope can include screening equipment, clarifiers, sludge dewatering equipment, biological treatment equipment, and tertiary filtration systems.
| Scenario | Capacity | Process | Key Considerations |
| Rural | 10–50 m³/d | Integrated AO wastewater treatment solution | Low energy consumption, unattended operation |
| Resort | 20–200 m³/d | Integrated AO or MBR wastewater treatment solution | Odour control and landscape integration |
| Residential | 200–1,000 m³/d | A²/O wastewater treatment solution | Large peak-to-average flow variation |
| School / Hospital | 100–800 m³/d | A²/O or MBR wastewater treatment solution | Enhanced disinfection for medical wastewater |
| Industrial park | 500–5,000 m³/d | A²/O or MBR wastewater treatment solution | Separate domestic sewage from industrial wastewater |
| Municipal Wastewater treatment plants | 1,000–50,000 m³/d | Complete municipal wastewater treatment solution | Class 1A effluent standard + sludge reduction |
