Do Cruise Ships Recycle Air

Its standard practice for the air conditioning systems of cruise ships to mix outside air with inside air to save energy.

Do cruise ships recycle air. Free cancellation before 48 hours. In ships you cannot filter the air well enough to stop viruses Health experts have warned about the potential for cruise ship outbreaks for years. Ryan David Kennedy PhD from John Hopkins University Bloomberg School of Public Health conducted a study on behalf of campaign group Standearth analysing the air pollution levels on board 4 different cruise ships over a 2-year span.

The wastewater treatment systems onboard the ships produce near-potable water quality. Chen stated that cruise ships could minimize the risk of transmission by simply using exclusively outside air and not recirculating it within the system -- a technique known as 100 percent fresh. Cruise ships generate high levels of air pollution that could endanger the health of passengers staff and port communities according to an undercover report released Thursday.

Such as onboard incineration plants recycling. Yes there are ships which do that. SOLAS mandates air circulation in all ships.

The problem is that these systems cant filter out particles smaller than 5000 nanometers. 10 of air pollution in the port city of Marseilles can be directly contributed. Rather than taking in a big breath of fresh air cruise lovers might actually be inhaling pollution on.

Ships used to be cooled by opening portholes but this rarely happens on modern ships. A ships ventilation system which relies on recirculated air filtered by medium-strength air filters is an efficient way of spreading virus particles from room to room aboard a ship said Chen. It keeps down the biggest risk to a ship and its cargo which is moisture.

Feb 13 2013. 40 facilities and activities. I would think on the cruise they would have no reason to recirculate air like airplanes do.
