Abstract:
1. A submerged-type, electrosorption-based water purification apparatus, comprising: a plurality of electrosorption-based purification reactors including a negative electrode for adsorbing and desorbing cations and a positive electrode for adsorbing and desorbing anions, among inorganic ions in water, and arranged in a tandem or parallel array; an inflow water storage/purification reaction bath a DC power supply system for supplying a positive and negative DC voltage of 0.1 to 2.0 volts to the electrosorption-based purification reactor via voltage-applying lines; a suction pump for forming a flow path of water by reduced pressure, in the arrow direction a three-way valve for transferring desalination water produced during a purification operation to a desalination water storage tank, and transferring discharged regeneration solution to a regeneration solution storage tank upon a regeneration operation; an electrical conductivity meter for setting reference conditions to conduct separate operation of the purification operation and regeneration operation and constantly monitoring the water quality of outflow water; and a control panel providing at least one function of operation setting conditions of the three-way valve, indication of electrical conductivity values, pump starting operation, adjustment of applied voltage, and indication of current values upon operation of the apparatus, wherein the electrosorption-based purification reactor is submerged in water to be treated.
