Waste Water Treatment System in Oasis of the Seas Cruise Ship

Cruise ships operators around the world have been criticized by the amount of waste water which they discharge into the sea. In the United States of America, all cruise ships or ships in general must meet the Alaska State Discharge Standards before their solid wastes and treated water can be discharged off the ship. Alaska standards are the most stringent regulation in the world. Even though the Oasis of the Seas spends most of her operating time in the Caribbean waters, she must meet the standards. Treated waste water that meets the standards can be released into the sea whereas the disposal of solid wastes can be done in an approved land based facilities.
The installation of Advanced Waste Water Treatment System in Oasis of the Seas was done by Headworks Bio Inc. The company uses Moving Bed Bio Reactor (MBBR) and Return Activated Sludge technologies in the system to purify hotel grey water; galley water; laundry and black water from the ship. Before these waters are fed into the Integrated Fixed Film in Activated Sludge (IFAS) , they have to be blended and separated from solid wastes. After passing through the IFAS bioreactor, the treated water will enter Positive Air Flotation Units and Secondary Polishing Barrier for further purification processes. The treated water still has to flow through the UV or Oxidation Disinfection Stage to finally meet the Alaska and IMO standards.  
This Cleansea Shipboard Water Treatment technology from Headworks Bio is based on Hydroxyl patented processes. The side products of this waste-water treatment system are the solids that can be fed into an incinerator or packed into bags for land based disposal.
In my personal opinion, even though the effluent water is now free from harmful components, it should not be pump into coastal areas that is very close to the coral reef environment. This is to maintain the salinity of the seawater in the coral reef areas in a stable level that allows marine creatures to thrive well without any disturbances from any human activities. by Charles Roring
