DuPont™ MBR Membrane Bioreactor System for Advanced Wastewater Treatment
Membrane Bioreactor (MBR) is an advanced wastewater treatment technology that combines biological treatment with membrane filtration to produce high-quality treated water. It is widely used for industrial wastewater treatment, municipal wastewater treatment, water reuse, and RO pretreatment.
WTB Water Solution PTE. Ltd., an Authorized Distributor of DuPont Water Solutions, supplies and exports advanced DuPont™ MemCor™ MBR and MemPulse™ MBR systems for industrial and municipal wastewater treatment projects worldwide.
What is MBR Technology?
A Membrane Bioreactor (MBR) combines the biological process of activated sludge treatment with membrane filtration. Unlike conventional activated sludge systems that rely on secondary clarifiers for solid-liquid separation, MBR uses membranes as a physical barrier to separate treated water from biomass.
This allows the system to maintain higher MLSS concentrations and achieve consistently high-quality effluent. DuPont states that MemCor™ MBR systems can operate at significantly higher MLSS concentrations than conventional activated sludge systems. DuPont
Key Benefits of DuPont™ MBR
1. High-Quality Treated Water
The membrane provides a physical barrier for suspended solids and produces consistently high-quality filtrate, making MBR suitable for demanding discharge and water reuse applications. DuPont
2. Compact Footprint
MBR eliminates the need for conventional secondary clarification and can significantly reduce the overall footprint of a wastewater treatment plant. DuPont
3. Lower Energy Consumption
DuPont's MemPulse™ MBR technology uses pulsed, plug-flow aeration designed to improve membrane cleaning efficiency and reduce aeration energy requirements. DuPont reports aeration reductions of up to 50% for the MemPulse™ system, depending on the application and operating conditions. DuPont
4. Excellent for Water Reuse
The high-quality effluent from MBR makes it an effective treatment step for applications where treated wastewater is intended for reuse or further RO treatment. DuPont
5. Modular & Flexible Design
DuPont MBR systems use modular membrane racks, allowing flexibility in system configuration and future capacity expansion. DuPont
6. Reduced Sludge Settling Problems
Because membrane filtration separates solids directly rather than relying on gravity settling, MBR is less dependent on sludge settleability than conventional activated sludge systems. DuPont
DuPont™ MemPulse™ MBR Technology
The MemPulse™ MBR system combines DuPont membrane filtration with a specialized pulsed aeration process. Large air bubbles move along the membrane surface, helping control solids accumulation while improving aeration efficiency.
DuPont's current MemPulse™ B50N module is designed for municipal wastewater, industrial wastewater, wastewater reuse, and RO pretreatment applications, with DuPont reporting specific energy consumption as low as 0.07 kWh/m³ in applicable configurations. Actual performance depends on wastewater characteristics and system design. DuPont
