How the MBR System Works
Membrane Bioreactor (MBR) technology is an integrated biological treatment and membrane filtration process in a single compact system. The Oxymo Technology MBR system produces high-quality effluent within a single unit, compared to a conventional sewage treatment plant that requires secondary clarifiers and further disinfection steps.
Step 1 — Screening & Pre-Treatment
Raw sewage enters the system and passes through a fine screen that filters out large objects, rags, and debris. This prevents damage to the downstream membranes and lowers the organic loading to the bioreactor.
Step 2 — Bioreactor (Biological Treatment)
Screened wastewater passes to the aeration tank, where oxygen is provided to activated sludge microorganisms which break down dissolved organic matter such as BOD, COD, ammonia, and nutrients. The MBR system maintains a significantly higher Mixed Liquor Suspended Solids (MLSS) concentration than conventional systems, giving more efficient treatment in a smaller tank volume.
Step 3 — Membrane Filtration
The treated wastewater then flows through Oxymo’s PVDF hollow-fiber or flat-sheet MBR membranes. The pore size ranges from 0.01 to 0.1 micron, which filters the removal of suspended solids, bacteria, and many pathogens. This results in treated water that is clear and of good quality, and consistently has good effluent quality.
Step 4 — Permeate Discharge or Reuse
The filtered permeate exits the system with BOD < 10 mg/L, TSS < 5 mg/L, and turbidity < 1 NTU. The treated water may be reused for irrigation, flushing toilets, industrial cooling systems, and other approved water reuse purposes. The MBR STP plant is fully automated and can operate with minimal supervision, making it suitable for sites without full-time operators.
Key Benefits
Oxymo Technology MBR membranes produce high-quality treated water that meets or exceeds CPCB Class A and NGT discharge standards. An ultrafiltration barrier eliminates secondary clarifiers and lessens dependence on chemical disinfection. Effluent is suitable for water reuse — landscaping, toilet flushing, and industrial processes.
- Single compact unit: Biological treatment and filtration are integrated, which is ideal for housing societies, hotels, hospitals, and urban commercial complexes with high land cost. The package system can often be containerized or installed below ground.
- Durable reinforced PVDF membranes: Oxymo’s embedded-reinforced PVDF membranes withstand elongation of up to 300% without fiber breakage under standard operating conditions. Membrane life is 5–8 years, which decreases the frequency of replacement and lifecycle cost.
- Low sludge generation: Higher biological activity results in lower excess sludge than conventional activated sludge, reducing disposal costs and sludge infrastructure.
- Automated operation: The package MBR system operates continuously or intermittently with very few operator interventions; controls manage aeration and membrane backwashing, and trigger alarms automatically, which is valuable for decentralized STPs where skilled operators are not available on site 24 hours a day.
- Modular scalability: Sizes range from 1 KLD up to 500+ KLD, with the addition of more membrane modules or treatment units without significant civil construction.
MBR vs. Conventional STP
The selection of the appropriate sewage treatment plant (STP) depends on effluent quality, space, operating costs, and water reuse. Below is a quick comparison of a Conventional STP and an Oxymo Technology MBR plant:
| Parameter | Conventional STP | Oxymo Technology MBR Plant |
| Solid–liquid separation | Secondary clarifier (gravity) | Membrane barrier (0.01–0.1 µm) |
| Effluent BOD | 20–30 mg/L typical | < 10 mg/L |
| Effluent TSS | 30+ mg/L | < 5 mg/L |
| Turbidity | Variable | < 1 NTU |
| Footprint | Large | 30–50% smaller |
| Secondary clarifier | Required | Not required |
| Disinfection chemicals | Higher | Reduced |
| Sludge production | Higher | Lower |
| Reuse readiness | Needs tertiary polishing | Reuse-ready |
| Automation | Limited | Fully automated (PLC) |
The Takeaway:
An MBR STP plant produces higher quality treated effluent, requires less footprint, and can be used for water re-use applications. It is compact and automated, and is well suited to modern residential, commercial, municipal, and industrial wastewater treatment projects.
Applications
Oxymo Technology MBR systems are deployed across a wide range of sectors in India and internationally, wherever a reliable, compact sewage treatment plant is required:
- Residential complexes, apartments & housing societies
- Hotels, resorts & hospitality
- Hospitals & healthcare facilities
- Commercial complexes, malls & office parks
- Schools, colleges & institutional campuses
- Municipal sewage treatment for towns & urban local bodies
- Industrial townships & remote / containerized installations
For housing societies, NGT rules and local laws in many states in India mandate the installation and operation of an on-site STP in housing complexes exceeding a specific size. Oxymo’s package MBR system is compact enough to fit into spaces a conventional plant can’t, while still meeting CPCB Class A effluent standards.

FAQs
A sewage treatment plant (STP) treats residential, municipal, and industrial wastewater to remove pollutants and contaminants. It uses physical, biological, and chemical treatment methods to create treated water that meets specific standards and can be used in approved reuse, including irrigation, toilet flushing, cleaning, or safe discharge, as appropriate in local water use regulations.
MBR systems typically have a higher upfront cost than conventional activated-sludge systems of equal capacity, but recover it through lower land cost (30–50% smaller footprint), lower chemical use, lower sludge disposal, and effluent reuse. Typically, the total lifecycle cost is lower over a 10–15 year time frame. Please contact us for a site-specific comparison and factory price.
Oxymo Technology MBR systems are designed for low-maintenance and automated operation. Routine maintenance involves periodic membrane cleaning, system inspection, and replacement of consumables. Chemical cleaning is typically performed every 3-6 months, depending on the quality of the wastewater. Maintenance contracts and operator training are also available.
