Airport Wastewater Treatment Project in Africa | Mejec SB Integrated Sewage Treatment System

As passenger traffic continues to grow across Africa, airports require reliable wastewater treatment systems to ensure environmental compliance while maintaining uninterrupted daily operations. To support this demand, Mejec successfully supplied its SB Series Integrated Wastewater Treatment System for an international airport domestic sewage treatment project in Africa.

Designed for stable operation, easy installation, and efficient biological treatment, the project demonstrates how Mejec's integrated wastewater treatment technology can provide dependable solutions for large-scale public infrastructure.

Project Overview

Reliable Wastewater Treatment for Airport Operations

Airports generate continuous domestic wastewater from passenger terminals, offices, restaurants, restrooms, and service facilities. These wastewater flows require consistent treatment performance despite daily fluctuations in water volume.

The Mejec SB Series Integrated Sewage Treatment System was selected because of its compact structure, modular design, and reliable biological treatment performance. Multiple treatment units were installed to match the airport's wastewater demand while allowing future capacity expansion if required.

The integrated design also minimizes civil construction work, shortens installation time, and simplifies operation and maintenance, making it particularly suitable for busy transportation hubs.

Advanced MBBR and MBR Biological Treatment Technology

The project utilizes a combination of Moving Bed Biofilm Reactor (MBBR) and Membrane Bioreactor (MBR) technologies.

MBBR Process

The MBBR system uses suspended biofilm carriers to increase microbial growth, delivering:

• High biological treatment efficiency

• Strong resistance to hydraulic and organic load fluctuations

• Stable long-term operation

• Reduced sludge production

MBR Process

The membrane filtration system further enhances water quality by effectively removing suspended solids and microorganisms, producing clear treated effluent suitable for strict discharge standards.

This technology combination ensures reliable wastewater treatment performance while maintaining a compact equipment footprint.

Stable Effluent Quality

The Mejec SB Series system consistently achieves the project's required discharge standards:

• COD ≤ 50 mg/L

• BOD₅ ≤ 10 mg/L

• NH₃-N ≤ 5 mg/L

• SS ≤ 10 mg/L

Stable effluent quality helps protect surrounding ecosystems while supporting sustainable airport operations.

Advantages of the Mejec SB Integrated Wastewater Treatment System

The SB Series offers several advantages for airport wastewater treatment applications:

• Modular integrated design for fast installation

• Compact footprint with reduced civil engineering costs

• High-efficiency MBBR and MBR biological treatment

• Stable performance under variable wastewater loads

• Low maintenance requirements

• Easy transportation and deployment

• Flexible capacity expansion through multiple units

• Suitable for remote or infrastructure-limited locations

Suitable Applications

In addition to airports, the Mejec SB Series Integrated Wastewater Treatment System is widely used in:

• International airports

• Hotels and resorts

• Tourist attractions

• Industrial facilities

• Commercial complexes

• Schools and universities

• Hospitals

• Residential communities

• Government facilities

• Remote infrastructure projects

Conclusion

The successful implementation of the Mejec SB Series Integrated Wastewater Treatment System at this African international airport demonstrates its ability to deliver reliable, high-quality domestic sewage treatment for demanding public infrastructure projects.

By combining advanced MBBR and MBR biological treatment technologies with an integrated modular design, Mejec provides efficient, scalable, and environmentally responsible wastewater treatment solutions for airports and other large-scale facilities worldwide.
