Abstract: The present invention relates to water treatment process using pyrophylite ceramic membrane which purifies contaminant from wastewater by applying the pyrophylite ceramic membrane with immersion type, more particularly, in the water treatment process using the pyrophylite ceramic membrane including pyrophylite with 80 weight and alumina with 20 weight, characterized that comprises a S-1 step which pyrophylite ceramic membrane 10 is embedded and raw water is supplied to a reactor 100 blocked from outside, a S-2 step which obtains permenate water by operating suction pump 130 connected with the pyrophylite ceramic membrane 10, a S-3 step which recovers gas generated from the reactor 100 and a S-4 step which circulates part of gas generated from the reactor 100 to the reactor 100.
