BioBarrier® Marine MBR Membrane Bioreactor

Advanced Membrane Bioreactor Wastewater Treatment for Vessels and Offshore Platforms

The BioBarrier Marine MBR is a high-performance membrane bioreactor (MBR) system designed to deliver ultra-clean, disinfected effluent from marine wastewater. Combining biological treatment with advanced membrane filtration, it provides one of the highest levels of wastewater purification available for ships, yachts, and offshore facilities.

Why Choose the Marine BioBarrier System?

Exceeds IMO Standards

Engineered to surpass IMO MEPC.227(64) requirements, including nutrient removal for sensitive discharge zones and environmentally focused operations.

Supports Full Onboard Treatment

Ideal for total blackwater and graywater applications, as well as water reuse processes onboard.

High Treatment Efficiency

Removes 99.9% of pollutants and contaminants typically found in vessel sewage streams.

How It Works

  • Wastewater enters the biological treatment zone, where naturally occurring microbes break down organic matter
  • It then flows through a submerged ultrafiltration membrane, which physically separates solids, bacteria, and viruses
  • The result is crystal clear, disinfected effluent- ready for overboard discharge or reuse
  • Fully automated controls and minimal operator involvement ensure safe, consistent performance
