[ABSTRAK
Meningkatnya air limbah minyak bumi, maka diperlukan pengolahan yangbaik. Proses fotolisis merupakan pengolahan yang tepat dan penambahan katalisTiO2 untuk mempercepat prosesnya. Objek studi penelitian ini adalah Air limbahproduksi minyak bumi dan gas pada Instalasi Pengolahan Air Limbah (IPAL) diPT. Pertamina (Persero) RU III, Plaju, Sumatera Selatan. Penelitian eksperimentaldilakukan pada skala laboratorium. Proses ini dilakukan dengan menyinari sampelair limbah dengan lampu UV dan ditambahkan katalis TiO2. Katalis TiO2memiliki ukuran partikel hingga mencapai 5 μm, tingkat disperse rendah, dantingkat kemurnian 100%. Air limbah produksi memiliki debit 40 m3/jam dengankualitas influen rata-rata COD 1035,7 mg/l; Fenol 246,6 mg/l; Suhu 28,8oC; pH8,95; Amonia 0,076 mg/l; Sulfida 246,6 mg/l; dan tidak terkandung Minyak danLemak didalamnya. Variasi yang dilakukan pada penelitian ini dosis katalis,waktu kontak, dan pH. Konstanta degradasi COD pada hubungan waktu kontaktehadap removal COD yaitu k = 0,0074 min-1 pada pH 4. Kondisi optimumpengolahan berada pada pH 4, dosis optimum100,8 ppm, dan waktu kontak 150menit mencapai removal 69,154%.
ABSTRACT
The increase of petroleum wastewater needs the better treatment.Photolysis is the proper processing with catalyst TiO2 to accelerate the process.The object study is Wastewater of Oil and gas Refinery Production at WasteWater Treatment Plant (WWTP) at PT. Pertamina (Persero) RU III, Plaju, SouthSumatera. This experimental research conducted in laboratory scale. This processis carried out by irradiating the sample by UV rays which has been added TiO2catalyst. The size of catalyst TiO2 is up to 5 μm, has low disperse, and 100%purity. Wastewater discharge production has 40 m3/day with the quality ofinfluent COD 1035.7 mg/l, Phenol 246.6 mg/l, Temperature 28.8oC, pH 8.95,Ammonia 0.076 mg/l, Sulfide 246.6 mg/l, and there wasn?t oil in it. This processis carried out by irradiating the sample by UV rays which has been previouslyadded TiO2 catalyst. Variations to be conducted in this study is the catalystdosage, contact time, and pH. The constant degradation of COD on therelationship of time contact against the removal of COD that is k =0.0074 min-1 atpH 4. Treatment optimum condition at pH 4, catalyst dosage 100,8 ppm, andcontact time 150 minutes has reached 69.154% of COD removal;The increase of petroleum wastewater needs the better treatment.Photolysis is the proper processing with catalyst TiO2 to accelerate the process.The object study is Wastewater of Oil and gas Refinery Production at WasteWater Treatment Plant (WWTP) at PT.
