Containerized A²O-MBR Integrated Wastewater Treatment Plant 1

Containerized A²O-MBR Integrated Wastewater Treatment Plant 2

Containerized A²O-MBR Integrated Wastewater Treatment Plant

The QILEE A²O-MBR Series is our flagship solution for achieving the highest standards in nutrient removal and water reuse. This advanced system integrates the Anaerobic-Anoxic-Oxic
(A²/O) process-an enhancement over the A/O process for superior biological phosphorus removal-with the unparalleled solid-liquid separation of Membrane Bioreactor (MBR) technology.

Housed within a ruggedized shipping container, this all-in-one plant delivers exceptional effluent quality that consistently meets stringent reuse and discharge standards. It is the ultimate choice for projects requiring robust, reliable, and compact wastewater treatment with a focus on total nitrogen and phosphorus control.

Key Features & Benefits

Superior Nutrient Removal

The A²/O process is specifically designed for simultaneous and efficient removal of Total Nitrogen (TN) and Total Phosphorus (TP), alongside BOD and COD, effectively combating eutrophication.

Exceptional, Reusable Effluent

The MBR filtration barrier produces crystal-clear, disinfected water with turbidity < 0.2 NTU and undetectable suspended solids, making it ideal for high-quality non-potable reuse.

Ultra-Compact & Mobile

The system's footprint is minimized by consolidating biological treatment, and filtration into a single containerized unit, offering significant space savings.

Plug-and-Play & Rapid Deployment

Every unit is fully factory-integrated, tested, and shipped ready for operation. On-site work is minimized, drastically reducing installation time and civil costs.

Full Automation with Smart Controls

An intelligent PLC system manages the entire process, including recycle flows, aeration, and membrane maintenance. Optional cloud-based IoT monitoring enables real-time oversight and control.

Process Resilience

The high MLSS concentration within the MBR and the multi-stage biological process provide outstanding stability against flow and load fluctuations.

Key Features of QILEE Containerized Seawater Desalination System

The synergy between A²/O and MBR creates a superior treatment platform:

The A²/O Process provides a dedicated anaerobic zone at the head of the process, promoting the growth of PAOs (Phosphorus Accumulating Organisms). These organisms uptake volatile fatty acids and subsequently release phosphorus, leading to enhanced biological phosphorus removal in the aerobic zone, reducing chemical consumption.
The MBR Technology retains all biomass, including slow-growing nitrifiers and PAOs, within the bioreactor. This results in a more diverse and effective biomass population and completely independent control of hydraulic and solids retention times.
