The Brewery Wastewater Challenge
High BOD Load
Compliance Issues & Surcharge Fees
Limited Space for Equipment
Batch Operations & Inconsistent Flow
Breweries produce wastewater with exceptionally high organic loads—BOD (Biochemical Oxygen Demand) levels frequently range from 3,000 to 10,000 mg/L, far exceeding residential values and triggering municipal surcharge fees or compliance issues. Without effective treatment, surcharges and discharge restrictions can become a major operational and financial burden. Enereau’s nrPUR™ MBR system provides a compact, modular solution that delivers consistent, reliable results even under variable flows and loadings.
The Enereau Solution: nrPUR™ High-Strength MBR Systems.
>98% BOD Removal
Handles Variable Flows from Batch Production
Modular Design Fits Tight Spaces
Effluent Suitable for Safe Discharge or Reuse
Enereau’s nrPUR™ MBR is specifically designed to handle high-strength brewery wastewater with a compact footprint and low maintenance.
The system delivers over 98% BOD removal, producing final effluent typically under 5 mg/L for BOD, TSS, and TN making it ideal for safe discharge or water reuse. Its modular components are designed to fit within tight brewery footprints, enabling fast and flexible deployment. Low-energy ultrafiltration (UF) combined with automated backwash ensures robust performance with minimal operator intervention. To maintain membrane integrity and optimize throughput, continuous air scouring actively controls biofilm buildup, ensuring reliable operation even under high-strength, variable-flow conditions.
In addition to full scale on-site wastewater treatment Enereau also supplies pre- and post-treatment options. These include pH adjustment, fine screening, flotation, as well as polishing steps like UV disinfection and carbon filtration. These modular, stand-alone units can either support municipal discharge targets or form a part of a complete system.

The nrPUR™ MBR Technology
The nrPUR™ Membrane platform is a low-energy, self-cleaning ultrafiltration (UF) system for the treatment of low- to high-strength wastewater to high-quality discharge or reuse standards. The technology is highly flexible and suitable for both domestic and industrial wastewater. Configured around a series of modular process building blocks, nrPUR™ platform offers unparalleled flexibility and reliability for wastewater treatment on wastewater streams from 300 mg/L to 10,000 mg/L, producing effective TSS & BOD5 reduction of >98%, safe, reuse-quality water. When combined with our advanced polishing technologies the nrPUR™ MBR system can treat trace micro pollutants (e.g. Phosphorus, Ammonia, etc) to safe discharge levels.
