Title:
PHYSICAL WATER PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/075511
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a physical water purification system having a performance deterioration prevention function that compensates for a performance deterioration problem occurring when a physical water purification system according to the prior art is used and that can reflect various domestic and overseas water quality characteristics, and provided is a photocatalytic oxidation apparatus which disinfects Legionella bacteria or general bacteria found in coolant or contaminated water, decomposes organic contaminants, prevents pipe corrosion through dissolved oxygen removal and can also remove scale components, wherein, to activate the chemical reaction of the photocatalytic oxidation apparatus, photocatalyst particles themselves are generated through the processes of alkali and heat treatment of Nb-Ti laminates and alloy rods and can be used semi-permanently. The present invention also relates to: an electrolysis device capable of more efficiently removing scale components; and a physical water purification system for performance deterioration prevention, comprising a scraper using an insulating material plastic or ceramic plate used to solve electrical discharge problems, and a ball filter device which can improve turbidity by filtering turbid substances or scale particles.
