Preliminary ozonation of water, in this case, is carried out with ozone concentration 1.5-10 g/cu.m for 25-30 min. Filtering carbon material from the two steps is regenerated by water stream directed from below upward with velocity 15-25 m/h and simultaneously feeding air in amount 2-3 cu.m per 1 cu.m of fed water for 20-30 min with periodicity 24 h. Additional regeneration of second-step carbon material is performed by treating material with boiling water heated by 120-200 C steam passed through water from below upward in amount 0.5-1 kg/h per 1 kg of material for 20-60 min with periodicity 240- 360 h followed by washing the bed with water-air mixture in above- indicated proportion.
