As cities continue to grow, sewage treatment has become a crucial aspect of environmental protection. To tackle the rising issue of water pollution, MABR (Membrane Aerated Biofilm Reactor) sewage treatment technology has emerged. With its high efficiency, environmental benefits, and energy-saving features, it represents a cutting-edge solution in the field of sewage treatment.

What is MABR Technology?

MABR technology blends the advantages of oxygen-permeable membranes and biofilm methods. Its innovative design allows for simultaneous nitrification and denitrification within the same reactor, significantly enhancing wastewater treatment efficiency. In this system, a biofilm forms on the outer surface of the membrane, and oxygen is supplied through the membrane itself. This unique mechanism enables bubble-free aeration, minimizing energy consumption and reducing the environmental impact associated with traditional aeration methods.

How Does MABR Work?

The MABR wastewater treatment process begins with sewage passing through a grating system to remove floating debris and sediment. It then enters a regulating tank for adjustments in water quality and quantity. Following this, a lifting pump directs the sewage into the MABR membrane tank, where organic pollutants are degraded, and ammonia nitrogen is removed through direct contact with the multi-layered biofilm of the MABR.

Inside the biofilm, different zones exists in the order of aerobic zone, active anaerobic zone, and active anoxic zone, all exists within one system, facilitating the growth and metabolism of diverse microorganisms. This collaboration significantly enhances the overall sewage treatment effectiveness.

Advantages of MABR Technology

MABR wastewater treatment equipment offers numerous benefits:

1. High Efficiency: MABR’s direct oxygen transfer yields efficient and stable biofilm development. The unique biofilm ensures stable effluent water quality, with significant reductions in parameters like COD (Chemical Oxygen Demand) and TN (Total Nitrogen).

2. Compact Design: The system occupies minimal space, which is advantageous for urban installations.

3. Low Energy Consumption: MABR operates automatically, and requires significantly less power to operate, reducing both operational costs and maintenance challenges.

4.Reduced Sludge Production: The technology decreases the generation of residual sludge, improving economic and environmental outcomes.

Real-World Applications

MABR technology is successfully being implemented across various sectors, including surface water quality improvement, municipal wastewater treatment, rural sewage handling, and aquaculture wastewater recycling. For instance, in Tianjin’s Beiyubao Industrial Park, an MABR upgrade project greatly enhanced the stability and quality of sewage treatment while also cutting both energy consumption and operating costs.

Looking Ahead

With ongoing technological advancements and a heightened awareness of environmental issues, MABR sewage treatment equipment is poised to play an even more significant role in the future. It not only addresses water pollution effectively but also supports the sustainable development of communities. By deploying MABR technology, we take an important step toward creating cleaner, healthier water bodies and promoting ecological balance.
