A purification device for water has a housing with a longitudinal axis, an upper and a lower end and a substantially round cross section. The device includes a first receptacle, arranged parallel to the longitudinal axis of the housing, for a first purification medium, and a second receptacle, which is also arranged parallel to the longitudinal axis of the housing, for a second purification medium. The receptacle for the second purification medium is arranged eccentrically with respect to the longitudinal axis of the housing.

Provided is a separation membrane leaf and a spiral wound module and an apparatus including the same, the separation membrane leaf comprising a separator, a supply-side flow channel material, and a permeation-side flow channel material comprising a tricot, the tricot comprising an adhesive part, and at least a part of the adhesive part being a low density part of the tricot, compared to the rest, wherein the tricot comprises at least one wale, at least one course, and an intersection point at which the at least one wale and the at least one course intersect, and the average distance between two intersection points arranged in parallel in the direction in which the wale of the low-density part is arranged is at least 1.25 times the average distance between two intersection points arranged in parallel in the direction in which the wale of the part other than the low-density part is arranged.

An emitter apparatus is mounted on a marine structure powered by wind or marine hydrokinetic energy to disperse a carbon dioxide sorbent such as sodium hydroxide. The sorbent can be generated by reverse osmosis of seawater with electrolysis of the brine, or delivered from an external supply. Suitable marine structures include offshore wind turbines, marine hydrokinetic generators, offshore oil platforms, merchant vessels, and other fixed and mobile structures. Effective capture is made by dispersing a fine mist or fog of aqueous sorbent from nozzles with a particle size from a nozzle of less than 100 microns. The sorbent reacts with atmospheric carbon dioxide forming carbonates and bicarbonates, which drift and fall to the ocean surface, reducing surface acidity and capturing additional atmospheric carbon dioxide via absorption at the local ocean surface. The resulting carbonates sink to the ocean floor and are there sequestered.

This reverse osmosis membrane processing method comprises adjusting processing-target water to a pH range of 4 to 8 and passing the water through a reverse osmosis membrane device. The reverse osmosis membrane processing method is characterized in that alkaline water having a pH of 9.5 or higher is brought into contact intermittently with the reverse osmosis membrane of the reverse osmosis membrane device. Raw water may be preprocessed with active carbon, or the like, to serve as the processing-target water. If the processing-target water has a pH of 9.5 or higher, this processing-target water may be used as the alkaline water.
