• Advanced Waste Water Treatment

Membrane Bioreactor

G&O Advanced Waste Water Treatment Plant in Full Compliance with IMO MEPC 227(64) Regulations

Advanced design

Gertsen & Olufsen A/S is a maritime solutions provider meeting the toughest requirements. We combine the use of cost-effective solutions with cutting edge technology, without compromising of the environmental concerns. Gertsen & Olufsen is using an activated sludge process combined with an anoxic nitrogen removal and simultaneous phosphorus precipitation.

Sludge, solids as well as E-Coli separation before ultrafiltration/membrane unit combined with a biological oxidation unit. The membrane sewage treatment design and technology are based on the thorough and operational experiences gained with more than 900 conventional units delivered and in operation worldwide since 2002. This has proven that G&O sewage treatment plants offer high efficiency, fully operational flexibility of the vessel and low maintenance requirements. 

Additional key features: 

  • 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.
  • Tailor-made split units – e.g. for retrofit projects.
  • Minimum maintenance requirements 
  • Danish design, made in EU, fitted with high-end quality components from reliable long term European suppliers
  • Designed for gravity and vacuum systems.
  • Low power consumptions.
  • Easy operation/minimum manual operation.
  • Easy access for inspections.
