In the ever-changing domain of wastewater treatment, Membrane Bioreactor (MBR) technology stands out as a robust and reliable membrane-based solution for industries seeking efficient and sustainable treatment options.
At GreenPebble Tech (GPT), we specialize in innovative and proprietary functionalized hollow fiber membrane bioreactor (MBR) technology. This technology integrates biological treatment with membrane filtration to deliver superior treated water quality.
The Advantages of Hollow Fiber MBR Technology
This technology uses ultrafiltration or microfiltration membranes instead of traditional secondary clarifiers. It retains suspended solids and microorganisms in the bioreactor. This creates a compact, high-performance system suitable for treating municipal and industrial wastewater. It can handle challenging streams from food and beverage, pharmaceuticals, and textiles.
Hollow fiber MBRs are particularly valued for their ability to handle variable loads while producing water suitable for reuse or safe discharge. As regulations tighten and water scarcity grows, adopting MBR can enhance operational efficiency and environmental compliance.
GPT's functionalized hollow fiber MBR system offers distinct benefits over conventional activated sludge processes. Here are the primary advantages:
Longer Membrane Life:
Inherently functional low-fouling membrane design allows longer backwash and chemical cleaning frequencies. This improves membrane lifespan to 10-15 years or more with proper maintenance, thus lowering replacement frequency and costs.
High Wastewater Recovery:
Exceptional effluent quality with removal rates exceeding 99% for suspended solids, BOD, and COD. This enables recovery rates of up to 95% or higher, facilitating water reuse in non-potable applications like cleaning, washing, flushing, or process cooling, thereby conserving valuable natural freshwater resources.
Complex Wastewater Treatability:
Our specifically engineered MBR can handle complex and recalcitrant wastewaters containing organics, inorganics, and pathogens efficiently. By maintaining high biomass concentrations up to 12,000 mg/L MLSS, our MBR can effectively degrade complex industrial pollutants without the need for extensive pre-treatment.
Lower Cost of Ownership:
Compact footprints cut land and construction costs by 50-70% compared to traditional systems. Energy-efficient operations, 30-50% less sludge, and reduced chemical use lower OPEX, resulting in favorable ROI with payback periods often under 3 years.
Additional distinct features include a smaller environmental footprint, automated operations for ease of use, and resilience to shock loads, ensuring consistent performance.

Applications of GPT's MBR Technology
GPT's MBRs have been successfully implemented in numerous applications and industrial segments. They are in continuous operation under demanding conditions without major issues.
Municipal Wastewater:
Upgrading existing plants to meet stringent discharge standards.
Industrial Sectors:
Treating effluents from food processing, pharmaceuticals, dairies, breweries, textiles, and chemical manufacturing.
Decentralized Systems:
For remote residential and commercial sites, hotels, or communities where space is limited.
Water Reuse Projects:
Producing reclaimed water for agriculture, industry, or groundwater recharge.
In food and beverage applications, MBRs manage high-organic loads effectively, converting waste into reusable resources.
How to choose the right type of MBR system?
Choosing the right Membrane Bioreactor (MBR) system for wastewater treatment depends on multiple technical, economic, and site-specific factors.
Some points to consider before choosing an appropriate MBR system is as follows:
Pilot test whenever possible (1–3 months) — fouling behaviour is site-specific.
Calculate Specific Energy Consumption (kWh/m³), not just air scour rate.
For submerged systems: choose modules with reinforced fibers with robust control of MLSS (<9 g/L).
Never undersize aeration: coarse bubble aeration is 50–70% of total energy in submerged MBRs.
Consider hybrid processes: e.g., ASP + MBR or MBR + Polishing Filtration for high-strength waste.
Case Study: MBR in Food and Beverage Wastewater Treatment
A successful commercial installation and commissioning of a 50 m³/hr capacity MBR from the food and beverage industry demonstrated the efficacy of Hollow Fiber (HF) MBR systems. Integrated with conventional pre-treatment, the HF MBR treated effluent with initial COD levels of 2,000-3,000 mg/L and BOD of 1,200-1,800 mg/L.
Key outcomes included:
Superior Performance:
The HF configuration achieved over 98% COD removal and 99% BOD reduction, outperforming Flat Sheet alternatives in flux stability and fouling resistance.
Operational Efficiency:
Membranes maintained high permeability with minimal cleaning, supporting longer life and lower maintenance.
Water Recovery:
Effluent met reuse standards, enabling more than 95% recovery for plant processes, reducing freshwater intake.
Cost Benefits:
Lower energy use (1.2-1.5 kWh/m³) and reduced sludge handling contributed to a 20-30% drop in ownership costs.
This implementation highlights GPT's MBR suitability for a challenging and complex food and beverage sector. Variable flows and high organics are common, delivering reliable treatment and sustainability gains.
