Challenges Brought by Upgraded Sewage Discharge Regulations in Southeast Asia
Since 2023, many countries in Southeast Asia have tightened environmental protection standards:
- Thailand: The newly revised "Water Act" requires BOD < 20mg/L.
- Indonesia: The Jakarta Bay project mandates a total nitrogen removal rate of over 70%.
- Singapore: PUB has launched the NEWater recycled water certification.
Traditional treatment processes are facing the crisis of elimination! Baihui Pu Environmental Protection helps customers easily meet standards through a three-level enhanced process and intelligent control.
Core Technology Analysis of Baihui Pu Skid-mounted Equipment
1. Composite A3O-MBR Process
Raw water → Bar screen → Equalization tank → Anaerobic tank → Anoxic tank → Aerobic tank
↑ ↓ ↑
Carbon source addition Nitrate-rich liquid recirculation Membrane separation system
▷ Dual enhancement of nitrogen and phosphorus removal: Patent fillers in the anoxic section improve denitrification efficiency
▷ Membrane system advantages: 0.1μm pore size hollow fiber membrane, effluent SS < 5mg/L
2. Intelligent Control Center
- PLC system automatically regulates:
⚫ Aeration volume (based on real-time feedback from DO sensors)
⚫ Chemical phosphorus removal agent dosage (based on online TP monitoring)
⚫ Membrane fouling control (intelligent backwashing program)
Customized solutions for special scenarios in Southeast Asia
Scenario 1: Island resort
➤ Configure seawater desalination pretreatment module
➤ The effluent meets the non-potable reuse standard of ISO 30500 and is used for landscape irrigation
Scene 2: Muslim Community
- Avoid designs featuring pigs, dogs, and other animals on the equipment's appearance.
- Obtain Halal Assurance System (HAS 23000) certification for production.
Scene 3: Flood-prone Area in the Rainy Season
► Flood-resistant Design: Control cabinet elevated by 1.5 meters
► Emergency Mode: Automatically switch to high-flow bypass during heavy rainstorms
Successful Case: Wastewater Treatment Project for a Food Factory in Vietnam
Background:
✔ Daily treatment capacity: 300 tons
✔ Requirement: Meet the QCVN 14:2020/BTNMT Class A standard
