Abstract: PURPOSE: A water treatment system by forward osmosis system and a control method thereof effectively control magnetic particles by arbitrarily controlling the position of each magnet and effectively prevent the magnetic particles from sticking to the surface of a separation film to bring about membrane fouling when the magnetic particles are used as an induction solute. CONSTITUTION: A water treatment system by forward osmosis system has a forward osmosis module (100) separated into an inflow water part (110) and an induction liquid part (120) by a separation film. The water treatment system uses induction liquid including magnetic particles as an osmosis induction solute. One part of the inflow water part accommodates a first magnet (111) and one part of the induction liquid part accommodates a second magnet (121). The gap between the first magnet and the separation film (130) of the forward osmosis module is greater than the gap between the second magnet and the separation film of the forward osmosis module. The repulsive force between the second magnet and the first magnet separates magnetic particles in the induction liquid from the separation film.

Abstract: PURPOSE: An advanced sewage-wastewater treatment system and a method are provided to reduce the energy used in a process remarkably since a pressure is not applied to a membrane in use at the time of separation and to prevent a membrane entanglement phenomenon since the degree of membrane contamination generated by a pollution source water flowed in is not serious. CONSTITUTION: An advanced sewage-wastewater treatment system comprises a normal osmosis module (300): an induced solution separating apparatus (400), and an ammonia removal apparatus (500). A normal osmosis module is installed at a rear end of the first precipitation tank (200) which treats the inflow water flowed through a settling basin (100) by the first precipitation. A normal osmosis module comprises an inflow water part (310) in which the first processed water treated in the first precipitation tank is flowed in, a membrane (320) passing the water only in the first processed water due to a normal osomosis phenomenon by an osmotic pressure difference, and an induced solution part (330) in which an induced solution inducing an osmotic pressure difference at the boundary of a membrane. An induced solution separating apparatus separates an induction solution and water from a diluted induction solution which is discharged from an induction solution part of a normal osmosis module, supplies the separated induction solution again to an induction solution part of a normal osmosis module, and discharges the separated water to outside.
