The EVAC MBR (membrane bioreactor) is an advanced wastewater treatment process that can treat all wastewater streams to current standards.

Together with our international partner EVAC, HIFraser have access to collective worldwide experience in designing, supplying and servicing sewage treatment systems for the marine environment.

Using the latest technologies allows us to customise systems to suit individual requirements and provide both environmentally sustainable and economically efficient solutions.

The two main types of sewage treatment plants we offer are biological and physicochemical.

The key features of EVAC’s Advanced Membrane Bio-Reactor (MBR):

  • Fulfils IMO MEPC 159(55) requirements
  • Low power consumption
  • No dilution water required
  • No disinfection required
  • No dechlorination required
  • 10+ years expected lifetime for membranes
  • Low operation costs

The compact footprint of the membrane bioreactor makes it ideal for retrofit to existing vessels, as well as for installation on new ships. The quality of effluent is extremely high in all sea conditions and exceeds all current specifications.
