Conventional bioreactor

Biological cleaning, removing E.coli

The bioreactor is a 100% biological treatment system,
which uses a fixed biofilm combined with UV treatment for
a sustainable solution. The system can handle all grey and
black water from any vessel or offshore facility with no need
for filters, dilution or chemicals during normal treatment.

This system lives up to IMO requirements.

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.

Before going into the cleaned water tank ready for discharge, the water passes through a UV filter to kill any remaining bacteria, including E.coli. The process is entirely free of manmade chemicals.

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.

  • 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 treatment systems we deliver 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.
