Advanced bioreactor

Biological cleaning, removing E.coli, phosphorous, nitrogen and microplastic

With the advanced bioreactor, it is possible to go beyond
regulations to protect the environment. It is a biological process in combination with a unique membrane treatment. In addition to this, phosphorous and nitrogen is removed, thereby living up to the rules for special areas in MEPC 227(64). The advanced solution is for those who face the toughest challenges, including cruise ships in protected waters and ship owners with an ambitious environmental agenda.

This system exceeds the strictest IMO regulations.

How it works

The fundamental process used in our bioreactors is 100% biological. There is no dilution or consumables. Waste water is led through several chambers and in the process is cleaned biologically with naturally occurring bacteria. The bacteria use oxygen to convert sewage into CO2 and water, leaving a small residue of sludge.

The water is treated biologically via an activated sludge process with natural occurring bacteria. This is combined with an anoxic nitrogen removal and simultaneous phosphorus precipitation. The water is then passed through a membrane unit where it undergoes an ultrafiltration process to retain any solids, which also includes removing E.Coli and filtering any potential microplastic.

Systems for new builds

We deliver system for new build vessels of any type and size from navy ships to large passenger ships.

Retrofitted systems

We can custom build bioreactors and fit them into even the tightest spaces on existing vessels.

Design options

  • Available in painted black steel and stainless steel
  • Work with both gravity and vacuum systems
  • Vacuum equipment, grease separation and sludge handling systems available
  • CE and ATEX systems available
  • Tailor-made split units e.g. for retrofit projects
  • Flexible control and operational features to switch in and out of specific areas
  • Custom designed systems e.g. where space limitations disqualify the use of standard systems
  • Full SCADA interface available
  • Unique 30 degree inclination operational approval

Simple and easily maintained

  • Minimum maintenance requirements and easy access for inspections
  • Easy operation with minimal manual operation
  • Built-in cleaned water tank and inlet tank
  • Danish design
  • Fitted with quality components from European suppliers
  • Low power consumption

We can deliver auxiliary solutions or connect with existing systems

Grease separating units

A well dimensioned grease separation is essential for a well functioning water treatment system for both black and grey water. Besides reducing the organic load of the treatment plant, it also prevents grease from building up in the vessel tanks and piping.

Vacuum collection solutions

The majority of our treatment systems are delivered with a G&O vacuum collection integrated into the system control and structure.

Sludge handling solutions

Sludge handling procedures will become a requirement in future marine regulations. We can dewater the sludge to minimise the volume of tanks required for storing sludge, returning water to the sewage treatment plant for processing before discharge.

Sludge can be incinerated or disposed as solid waste.
