Inside the Bioreactor.
Advanced Nutrient Removal.

It's not just a tank; it's a highly engineered ecosystem. Our A/O (Anoxic/Aerobic) configuration ensures complete Biological Nutrient Removal (BNR), destroying both organics and ammonia.

01

Anoxic Zone (Denitrification)

Oxygen is depleted here. Heterotrophic bacteria strip oxygen from nitrate (NO3-), converting it into harmless nitrogen gas (N2), effectively removing Total Nitrogen (TN) from the sewage.

02

Aerobic Zone (Nitrification)

Heavy aeration provides oxygen for aerobic bacteria to digest organics (BOD/COD) and convert toxic ammonia (NH3) into nitrate, which is then recirculated back to the Anoxic zone.

03

MBR Membrane Zone

Submerged directly in the high-MLSS sludge, the 0.1µm membrane acts as a physical barrier, drawing out crystal-clear water while keeping 100% of the bacteria inside the reactor.

How the Packaged Membrane Bioreactor (MBR) Works (Engineering Details)

Step 1: Mechanical Screening & Equalization. Raw domestic or medical sewage enters through a fine bar screen (1-2mm) to remove hair, plastics, and debris. The wastewater is temporarily held in an Equalization (EQ) tank to absorb peak flow shocks, a critical step for any containerized sewage treatment plant.

Step 2: Biological Denitrification (Anoxic Zone). The sewage is pumped into the Anoxic tank where oxygen is depleted. Here, specific heterotrophic bacteria utilize the organic carbon in the wastewater to strip oxygen from nitrate (NO3-), converting it into harmless nitrogen gas (N2). This process is essential for meeting strict biological nutrient removal (BNR) standards.

Step 3: Nitrification & Membrane Filtration (Aerobic Zone). The water flows into the heavily aerated MBR tank, which maintains a massive Mixed Liquor Suspended Solids (MLSS) concentration of 8,000 to 12,000 mg/L. Aerobic bacteria digest the remaining organics and convert ammonia to nitrate. Submerged directly within this sludge are the Kubota or Toray flat sheet MBR cassettes. A slight vacuum draws clear water through the 0.1μm pores, leaving 100% of the sludge and bacteria behind.

Step 4: Permeate Extraction & Disinfection. The highly purified permeate is extracted by suction pumps. Because the MBR membrane acts as an absolute physical barrier against pathogens, the effluent only requires a final UV polish or light chlorination before it is discharged or directly reused for unrestricted urban irrigation.

/ MODULE-08B / MICRO-ANATOMY

Submerged
Filtration Dynamics.

Unlike traditional settling clarifiers that rely on gravity, the MBR cassette is submerged directly into the high-concentration activated sludge. A suction pump creates a gentle vacuum, pulling pure water through the 0.1µm pores while air bubbles constantly scour the membrane surface to prevent clogging.

Hardcore FAQ.
Engineering-Grade Answers.

Flat Sheet (FS) is ideal for remote camps or high-grease environments because it requires zero backwashing and is virtually unbreakable. Hollow Fiber (HF) is chosen for large municipal projects where an extremely compact footprint is the priority.
For sensitive hospitality environments, we deploy our Underground Packaged MBR. The entire biological process is buried and sealed, with exhaust air routed through an integrated Active Carbon scrubber, ensuring absolutely zero odor at the surface.
Seeding the tanks with local activated sludge typically takes 2-4 weeks to reach the target 8,000 mg/L MLSS concentration. We provide a complete biological acclimatization manual and remote video guidance to ensure a successful startup.
Because MBR operates at a very high Sludge Retention Time (SRT) and MLSS concentration, the biological digestion is highly efficient. This means sludge production is drastically lower than conventional plants, requiring vacuum truck removal only every 3-6 months.
Yes. The 0.1μm to 0.4μm membrane pores act as an absolute physical barrier to bacteria and most pathogens. We combine this with robust UV and heavy Chlorination dosing to ensure zero viral load in the final effluent.
We provide a comprehensive 12-month mechanical warranty on all pumps, blowers, and PLC components. The MBR membrane cassettes carry a 3-year pro-rated OEM warranty, provided standard CEB cleaning protocols are followed.
For our containerized units, zero civil engineering is required. You simply pour a flat concrete slab, drop the container into place, and connect the main inlet, outlet, and power supply. It is a true plug-and-play solution.
