Abstract
Existing treatment leachate from Sarimukti Landfill doesn’t meet the quality standards of waste water.
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.
