STUDI OZONISASI SENYAWA ORGANIK AIR LINDI TEMPAT PEMROSESAN AKHIR SARIMUKTI

Existing treatment leachate from Sarimukti Landfill doesn’t meet the quality standards of waste water.<br />Preliminary treatment is necessary to break down persistent leachate compounds. Ozone can act directly or<br />indirectly with organic material (Glaze 1986). Column batch reactor system use one liter volume. Ozone is<br />pumped into the leachate in the form of fine bubbles. Variations include Ozone Pumping Flow, Ratio of<br />high/diameter (t/d), and pH. Kinetic Reaction of oxygen dissolution in the average leachate is zero order.<br />Increased pumping air discharge and increased pH makes ozone transfer process better. Best value occurs at pH<br />11, where the value of the reaction rate constant ozone 1.48. The average percentage of organic material<br />allowance 31% COD and 26% TOC. The decline TOC and COD have a tendency to be influenced by the pH<br />optimum 8-9. At alkaline pH makes carbonate (CO3) formed the greater, that make ozone compounds kill<br />quickly. FTIR results showed the intensity of hydroxyl groups increased after ozone oxidation where the<br />substitution of functional groups of organic matter associated with electrophilic addition reaction of oxygen<br />atoms. Existence Fulfic acid also increased the effect compounds and Humic Acid, Humad large has been cut by<br />radicals
