DRAW SOLUTE RECOVERING APPARATUS FOR FORWARD OSMOSIS PROCESS

摘要

PURPOSE: An induction solute collecting apparatus in a forward osmosis process is provided to maximize the energy efficiency in the forward osmosis desalination process by efficiently collecting ammonia and carbon dioxide in the form of ammonium salt without consuming additional water or with drastically small amount of water on the contrary to the conventional method. CONSTITUTION: An induction solute collecting apparatus in a forward osmosis process comprises a chamber(10); a gas injection part(20a) consisting of pipes; a charging unit(30); and an insulating waterproofing unit(40a) in a plate form. The gas injection part penetrates into one side of the chamber, and is separated from the other side. The charging unit is formed in the chamber higher than the gas injection part. The charging unit consists of at least one of a charging material or a coil. The insulation waterproofing part is positioned between the gas injection part and the charging unit within the chamber. The insulation waterproofing part is fixed to one side within the chamber, and separated from the other side. A heater(21a) is formed on the outside of the gas injection part.
