Abstract

The effluent discharged from the batik textile industry often contains azo compounds and organic contaminants. One method employed to address these pollutants is the Electrofenton (EF) technique. This study aims to assess the effectiveness of electrofenton in reducing both color content and COD (Chemical Oxygen Demand) in batik dyeing effluent. The Electrofenton process was conducted in batch mode, varying electrode distances at 4 cm and 6 cm, H2O2:FeSO4 molarity ratios of (10:0.05) and (10:0.1), and electric voltage strengths at 6 volts and 8 volts. The research revealed that employing an electric voltage of 8 volts, an electrode distance of 4 cm, a contact time of 120 minutes, and a Fenton dosage molarity of 10:0.05 M resulted in a remarkable removal efficiency of 97.8% with a final concentration of 103 mg/L for color content. Additionally, for COD, employing the same parameters led to a removal effectiveness of 90.1%, with a final concentration of 730 PtCo. The impact of Fenton dosage on COD removal was statistically analyzed using the t-test. The computed t-value of 3.444 surpassed the tabulated t-value of 2.776, indicating a significant influence of Fenton dosage on COD removal.

Abstract

Elektrokoagulasi merupakan teknologi pengolahan limbah cair menggunakan tegangan listrik. Elektrokoagulasi memanfatkan prinsip elektrokimia untuk mengendapkan berbagai pengotor didalam limbah baik bahan organik maupun anorganik. Penelitian ini bertujuan untuk mengetahui pengaruh variasi jarak elektroda dan waktu proses elektrokoagulasi terhadap persen removal COD, TSS dan Intensitas warna. Pada penelitian ini menggunakan elektroda Al-Zn dengan ukuran 5x10 cm dan reaktor elektrokoagulasi 20x16x16 cm. Jarak elektroda pada proses elektrokoagulasi ini divariasikan yaitu pada jarak 2, 4 dan 6 cm. Waktu proses yang digunakan yaitu selama 220, 240, 260, 280 dan 300 menit. Tegangan listrik dalam proses elektrokoagulasi yang digunakan 12 volt. Hasil penelitian menunjukkan Persen removal COD dan Intensitas tertinggi pada lama waktu elektrokoagulasi 300 menit yaitu 93,49% dan 95,5%. Sedangkan untuk persen removal TSS lama waktu elektrokoagulasi terbaik pada 280 menit sebesar 78,71%. Jarak antar elektroda terbaik menghasilkan persen removal COD, TSS, dan intensitas warna, pada jarak terbaik pada 2 cm.

Abstract

Waste treatment can be done in variousways. One of the methods that can be used isthe coagulation and flocculation method. Thecoagulant used can be either a chemicalcoagulant or a natural coagulant. Naturalcoagulants can be used in wastewatertreatment for % removal of BOD and %removal of COD. By using moringa seedcoagulant, it showed % removal of BOD of90.12% and % removal of COD in thepharmaceutical industry waste a maximum of71.23%. Through the use of tapioca starchcoagulants, % removal of BOD and CODwas 95.25% and 94.63%. The use of smallcrab chitosan coagulant showed % removalof both BOD and COD’s results was 32%and 31%.
