Preliminary treatment is necessary to break down persistent leachate compounds. Ozone can act directly or indirectly with organic material (Glaze 1986). Column batch reactor system use one liter volume. Ozone is pumped into the leachate in the form of fine bubbles. Variations include Ozone Pumping Flow, Ratio of high/diameter (t/d), and pH. Kinetic Reaction of oxygen dissolution in the average leachate is zero order. Increased pumping air discharge and increased pH makes ozone transfer process better. Best value occurs at pH 11, where the value of the reaction rate constant ozone 1.48. The average percentage of organic material allowance 31% COD and 26% TOC. The decline TOC and COD have a tendency to be influenced by the pH optimum 8-9. At alkaline pH makes carbonate (CO3) formed the greater, that make ozone compounds kill quickly. FTIR results showed the intensity of hydroxyl groups increased after ozone oxidation where the substitution of functional groups of organic matter associated with electrophilic addition reaction of oxygen atoms. Existence Fulfic acid also increased the effect compounds and Humic Acid, Humad large has been cut by radicals.}, issn = {2460-9919}, pages = {82--87} doi = {10.14710/teknik.v34i2.5630}, url = {https://ejournal.undip.ac.id/index.php/teknik/article/view/5630} }
