PURPOSE: A water purifier in which electrolysis separately produces weak alkaline water and strong alkaline water for medical use is provided. CONSTITUTION: A water purifier separates acidic water and alkaline water generated in a first electrolysis process to eject acidic water to an acidic water vent (14). Alkaline water is only flowed into a second housing (20) to produce acidic water, strong alkaline water and weak alkaline water. The separated acidic water is ejected to the acidic water vent (24). The strong alkaline water vent (25) uses a first solvalve (27) to separate a first outlet (28) of drinkable water for medical use and a second outlet (28a) of water for disuse. When producing water for medical use like strong alkaline, weak alkaline water falling under general drinking water is ejected to a vent (29) by using a second solvalve (31) without using a filter (30) by activated charcoal.

Abstract:
PURPOSE: An electrolysis purification treatment method of wastewater is provided to minimize unnecessary power consumption, and to prevent the generation of untreated source water as the appropriate power is supplied even if the contamination load increases. CONSTITUTION: An electrolysis purification treatment method of wastewater uses an electrolysis purification facility. The electrolysis purification apparatus comprises an electrolysis processing basin(10), a direct current supply(31), and a power supply controller(30). The concentration of residual free chlorine of treated water discharged after purification by electrolysis in an electrolysis treatment basin is measured using a residual free chlorine meter(40). The electric energy supplied to DC supply is reduced using the power supply controller so as to be inversely proportional to measured concentration of the residual free chlorine. The concentration of residual free chlorine is divided into multiple sections. The respectively different electric energy is allocated to each section.
