Abstract
The water purification process includes the steps of flocculating organic substances in a polluted water by adding a flocculant; and heating the polluted water or a supernatant obtained from the polluted water. The water purifying apparatus includes a flocculant adding unit configured to add a flocculant to a polluted water containing organic substances; and a heating unit configured to heat the polluted water or a supernatant obtained from the polluted water. Thus, organic acids contained in the polluted water can be removed from a large amount of the polluted water at high speed.
