  • Patent number: 10040533
    Abstract: A ballast water treatment apparatus for a ship includes a water collection part for collecting sea water, a forward osmosis process unit for producing ballast water and treatment water obtained by desalinating the sea water collected through the water collection part, and a ballast water tank for storing the ballast water produced by the forward osmosis process unit. Since the sea water is treated using a forward osmosis process, fresh water required within the ship can be supplied and the treated sea water can be used as ballast water. In addition, since waste heat and carbon dioxide generated in the ship are used to treat the sea water, the ballast water can be treated and produced in a low-cost and high efficient manner.

  • Patent number: 10016725
    Abstract: A forward osmosis process is provided, which includes separating a feed part and a draw solution part by a semi-permeable film. An ionic liquid is introduced into the draw solution part, and brine is introduced into the feed part. The brine has an osmotic pressure lower than that of the ionic liquid, so that pure water of the brine permeates through the semi-permeable film, enters the draw solution part, and mixes with the ionic liquid to form a draw solution. The draw solution was obtained out of the draw solution part to be left to stand at room temperature, so that the draw solution separated into a water layer and an ionic liquid layer.

  • Patent number: 9919272
    Abstract: The present invention relates to a separation membrane having both antibiotic and hydrophilic properties for water treatment and a preparation method thereof. In the separation membrane of the present invention, since an organic compound (antimicrobial and/or hydrophilic compound) is chemically conjugated to non-metal inorganic nanoparticles or metal nanoparticles, the nanoparticles are not eluted from the separation membrane even when the separation membrane is used for water treatment for a long period of time, so that the separation membrane may continuously maintain antimicrobial properties and high water permeability, is safe to the human body even when used for the treatment of drinking water, such as water purification, and exhibits characteristics in which stain resistance is also significantly enhanced due to antimicrobial and hydrophilic properties, which have been continuously imparted. Furthermore, high mechanical strength is exhibited by a metal or inorganic nanofiller introduced.
