Living in an underwater habitat requires gas treatment; an input of oxygen, the disposal of carbon dioxide and pollutants, and one kind of ‘carrier’ or inert gas (nitrogen or helium). Industrial divers live in a pressure complex on a support vessel and all air treating is done outside the habitat on the vessel. It seems there are not too many references of air being treated inside an underwater habitat. If we are mistaken do not hesitate to comment this article accordingly.
Several years ago Benjamin proposed a system of sensors inside the habitat measuring all necessary parameters like oxygen, carbon dioxide etc. and communicating among each other. Last days we talked about it again and found out, that it would still be a good solution. So we decided to publish it here again. Below you find the original thread, translated from German: Continue reading “Wireless Sensor Network (WSN)”
(Updated 04 April, 2017) In our undersea station one of the ways to absorb Carbon dioxide from the air and to produce oxygen instead might be beside classic scrubbers the Biocoil reactor that was first introduced by a science class of Cascade High School in the US. It looks like a quiet simple system based on Chlorella algae and it was used in Lloyd Godson’s ‘BioSub’ project in 2007.

The Triton is a sort of artificial gill that would extract oxygen from the water for you in an on-demand fashion as you swim, obviating the need for bulky SCUBA gear. Is this really possible? Find the answer on Deep Sea News.
Longer stays in an underwater station require systems to filter out Carbon Dioxide (CO2) from the air that is exhaled by the aquanauts. These CO2 scrubbers generally consist of a fan that pulls air through a canister filled with Carbon Dioxide (CO2) adsorbent, such as Sodasorb or Sodalime.
