PREOZONIZATION AS A BIOLOGICAL WASTEWATER TREATMENT INTENSIFICATION METHOD
DescriptionThe results of the research of wastewater treatment including pre-ozonization have been presented. The suitability of wastewater pre-barbotage in the storage tanks has been shown. Addition of ozone in small quantities (0,2 ÷ 0,02 g/m3) can improve the wastewater treatment results in the aeration process. Addition of ozone in small quantities doesn’t lead to the significant energy consumption at once. The treated wastewater transparency increases to 50 cm depth
