Abstract
Air limbah Personal Care masuk dalam kategori pharmaceuticals dan personal care products (PPCPs). Pengolahan biologis tidak dapat digunakan dalam pengolahan limbah jenis ini karena bersifat non polar. Pengolahan jenis limbah ini dapat dilakukan secara elektrokimia dengan menggunakan proses elektrokoagulasi (EC) dan elektrooksidasi (EO). Proses EC dilakukan dengan menggunakan konfigurasi elektroda Al-Al dan konfigurasi elektroda Fe-Fe sebagai anoda dan katoda. Elektrokoagulasi dilakukan dengan metode continue. EO dilakukan dengan sistem batch resirculation menggunakan air limbah efluen proses EC konfigurasi elektroda Al-Al dan Fe-Fe dengan material elektroda anoda Boron Doped Diamond (BDD), Ti/Pt dan Ti/IrO2 dan penggunaan kuat arus dalam proses EO yaitu 0,6 A, 0,7 A, 0,8 A dan 1,0 A. Parameter yang di ukur dalam proses EC yaitu COD, TSS, Turbidity dan pH, sedangkan dalam EO dilakukan pengukuran COD dan pH. Konfigurasi elektroda Al-Al dan Fe-Fe mempunyai keefektifan yang sama dalam menyisihkan COD, TSS, dan Turbidity dalam EC menggunakan air limbah personal care. Konfigurasi Al-Al menyisihkan COD, TSS dan Turbidity sebesar 76,1% (5,41 g), 90,3% (6,10 g), dan 82,6%; sementara konfigurasi Fe-Fe menyisihkan COD, TSS dan Turbidity sebesar 78,9% (5,78 g), 93,3% (6,62 g), dan 82,7%. Konfigurasi Fe-Fe menghasilkan perubahan nilai pH (4,8-6,65), sedangkan konfigurasi Al-Al tidak mengalami perubahan nilai pH. Elektroda anoda BDD dalam EO menghasilkan penyisihan COD yang efektif dibandingkan anoda Ti/Pt dan Ti/IrO2. Efisiensi penyisihan COD efluen EC(Al-Al) masing-masing adalah 70,46% (3,08 g), 34,30% (1,55 g) dan 39,71% (1,80 g); sementara dengan efluen EC(Fe-Fe) menghasilkan efisiensi penyisihan COD masing-masing adalah 73,28% (3,35 g), 56,99% (2,73 g) dan 39,83% (1,80 g) menggunakan anoda BDD, Ti/Pt dan Ti/IrO2. Peningkatan kuat arus memberikan pengaruh signifikan terhadap penyisihan COD. Anoda BDD menghasilkan penyisihan COD yang efektif dibandingkan dengan elektroda Ti/Pt dan Ti/IrO2 dengan kuat arus 0,6 A, 0,7 A 0,8 A dan 1,0 A. Dari keseluruhan uji elektrokoagulasi, konfigurasi elektroda Al-Al dan Fe-Fe efektif dalam meremoval COD, TSS, dan Turbidity. Namun, peningkatan nilai pH terjadi dengan menggunakan konfigurasi elektroda Fe-Fe. Hasil uji elektrooksidasi dengan kuat arus 1,0 A dan elektroda BDD menggunakan efluen EC konfigurasi elektroda Fe-Fe memberikan hasil optimum dalam mendegradasi COD dari air limbah personal care.

Personal Care wastewater is in pharmaceuticals and personal care products (PPCPs). Biological processing hard to use for treatment personal care wastewater because of character this waste is non-polar wastewater. Processing of this wastewater can be used electrochemically by using electrocoagulation (EC) and electrooxidation (EO) processes. The EC process is carried out using Al-Al electrode configuration and configuration of Fe-Fe electrodes as anode and cathode. Electrocoagulation was carried out using the continue method. EO is done with a batch resirculation system using EC effluent configuration of Al-Al and Fe-Fe electrodes with anode Boron Doped Diamond (BDD, Ti/Pt and Ti/IrO2 and. The use of current in the EO process is 0.6 A, 0.7 A, 0.8 A and 1.0 A. The parameters measured in the EC process are COD, TSS, Turbidity and pH, while COD and pH is measured in EO.
Configuration electrode of Al-Al and Fe-Fe have the same effectiveness in removing COD, TSS, and Turbidity in EC using personal care wastewater. Al-Al configuration gives result of removal COD, TSS and Turbidity at 76.1% (5.41 g), 90.3% (6.10 g), and 82.6%; while the Fe-Fe configuration gives result of removal COD, TSS and Turbidity by 78.9% (5.78 g), 93.3% (6.62 g), and 82.7%. The configuration of Fe-Fe resulted in changes in pH values (4.8-6.65), while the Al-Al configuration did not change the pH value (4.8-4.9). The variation of the BDD anode electrode in EO resulted in effective COD removal compared to Ti/Pt and Ti/IrO2 anode electrodes. The removal efficiency of effluent COD (ECAl-Al) was 70.46% (3.08 g), 34.30% (1.55 g) and 39.71% (1.80 g), respectively; while effluent (ECFe-Fe) produces COD removal efficiency of 73.28% (3.35 g), 56.99% (2.73 g) and 39.83% (1.80 g) using anodes BDD, Ti/Pt and Ti/IrO2. The increase in current strength has a significant influence on the allowance for COD. BDD anodes produce effective COD allowance compared to Ti/Pt and Ti/IrO2 electrodes with a current strength of 0.6 A, 0.7 A 0.8 A and 1.0 A.
As the result, the configuration of Al-Al and Fe-Fe electrodes in electrocoagulation was effective in remove COD, TSS, and Turbidity. However, using configuration Fe-Fe electrode increase pH value. The results of using 1.0 A and BDD electrode in electrooxidation using EC effluent configuration of Fe-Fe electrodes provide optimum results in degradation COD from personal care wastewater.
