World leaders in high recovery membrane solutions for maritime – ULTURA is the new name for the combined Rochem, Sepro Membranes and APTwater businesses. With over 40 years experience serving the major cruise lines, naval, yacht and offshore markets, ULTURA is a world leader in the development of specialist high recovery membrane technologies and systems for the most demanding marine environments to meet the latest International and EPA Vessel General Permit regulations.

Specialist in difficult to treat water in the marine sector – ULTURA offers a range of MBR, reverse osmosis and desalination solutions designed and serviced by a dedicated global network of marine specialists and field engineers.

Our range of technologies and services include: High quality drinking water through desalination known as our Reverse Osmosis Fresh water Generators. They use our patented Plate Tube (PT) Modules for small systems and our Space Tube (ST) Module for large systems. ULTURA also offers a highly effective gray and blackwater treatment using our Rochem designed and build Bio-Filt. It is a highly efficient and small footprint Membrane Bioreactor.

High quality drinking water
At ULTURA we provide seawater desalination that delivers high quality drinking water. Our reverse osmosis freshwater generators utilize patented open flow channel modules, Plate Tube (PT) module for small systems and Spacer Tube (ST) modules for large systems. These modules operate effectively and economically even at increased turbidity and Silt Density Index (SDI) levels for reverse osmosis. Systems capacities range from 200 liter/day up to 600,000 liters/day.

The benefits of our reverse osmosis freshwater generators

  • Cleans, sterilizes and desalinates seawater creating high quality, pure potable water
  • Uses our patented Plate Tube (PT) module for small systems and our Spacer Tube (ST) module for large systems
  • Low energy requirements with up to 70% energy savings
  • Proven reliability, low noise emitting, easy to operate
  • Approved by all applicable classification societies
  • No treatment chemicals needed
  • Self-controlled for continuous safe operation
Grey and black wastewater
Our Bio_Filt is a highly efficient and small footprint membrane bioreactor used for the treatment of gray and black water. Its innovative treatment technology replaces aerobic biological sewage plants aboard ships and in hotel complexes and villages. Based on a high-density biological process combined with a patented FM flat membrane module, Bio-Filt produces pure, clean discharge without requiring additional chlorination or other chemical treatment.
