Wastewater treatment
First Claim
1. A vessel for treating wastewater offshore, the vessel being positioned on the surface of a body of water and comprising:
- a hull;
a wastewater treatment system disposed at least partially within the hull, the wastewater treatment system being capable of treating at least 20 million liters per day of wastewater to yield end products comprising sludge and treated wastewater;
a wastewater intake in fluid communication with the wastewater treatment system;
an outlet for removing treated wastewater from the vessel; and
a mixing system for mixing at least one of the end products with water from the body of water, the mixing system comprising a mixing tank located on the vessel and comprising an inlet and an outlet.

Abstract
Offshore facilities, systems, and methods for treating wastewater have been developed. An offshore wastewater treatment facility include wastewater treatment components (for preliminary treatment, primary treatment, secondary treatment, and/or advanced treatment); a means for moving wastewater from a land-based site to the facility; a means for removing treated wastewater from the facility; and a means for removing sludge from the facility. A method of treating wastewater includes: transporting wastewater from a site on land to a wastewater treatment facility located offshore in a body of water, and subjecting the wastewater to preliminary treatment, primary treatment, secondary treatment, and/or advanced treatment.

15. A wastewater treatment facility situated in a body of water located offshore from a land-based wastewater collection system, the wastewater treatment facility comprising:
-
(a) a wastewater treatment component being capable of treating at least 20 million liters per day of wastewater, the component being selected from the group consisting of;
a primary treatment system for reducing the amount of suspended solids or greases in wastewater;
a secondary treatment system comprising bacteria capable of reducing the amount of organic matter contained in wastewater;
a disinfecting treatment system comprising a means for killing a microorganism; and
a nutrient removal system comprising a means for removing a nutrient comprising nitrogen or phosphorous from wastewater;(b) a means for moving wastewater from the land-based wastewater collection system to the wastewater treatment facility; (c) a means for removing treated wastewater from the wastewater treatment facility; and (d) a means for removing sludge from the wastewater treatment facility; wherein neither the means for removing treated wastewater from the wastewater treatment facility nor the means for removing sludge from the wastewater treatment facility operate to discharge sludge or treated wastewater into the body of water. - View Dependent Claims (16, 17, 18, 19)

20. A wastewater treatment facility situated in a body of water located offshore from a land-based wastewater collection system, the wastewater treatment facility comprising:
-
(a) at least a first wastewater treatment component and a second wastewater treatment component, each of the components being capable of treating at least 20 million liters per day of wastewater, and being selected from the group consisting of;
a primary treatment system for reducing the amount of suspended solids or greases in wastewater;
a secondary treatment system comprising bacteria capable of reducing the amount of organic matter contained in wastewater;
a disinfecting treatment system comprising a means for killing a microorganism; and
a nutrient removal system comprising a means for removing a nutrient comprising nitrogen or phosphorous from wastewater;(b) a means for moving wastewater from the land-based wastewater collection system to the wastewater treatment facility; (c) a means for removing treated wastewater from the wastewater treatment facility; and (d) a means for removing sludge from the wastewater treatment facility. - View Dependent Claims (21, 22, 23)
