Pengolahan Limbah Cair Industri Pestisida menggunakan Advanced Oxidation Process untuk Reduksi Chemical Oxygen Demand

Abstract

Limbah Cair Industri Pestisida memiliki karakteristik awal kadar COD dalam rentang 100.000 – 200.000 mg/l. Tujuannya mengidentifikasi karakteristik limbah cair industri pestisida, menentukan efektifitas metode Advanced Oxidation Process dan menghitung total biaya AOP skala industri. Uji AOP Photo Fenton dan Fenton limbah cair industri pestisida sebanyak 250 ml dicampurkan dengan FeSO4 dan H2O2 dengan variasi rasio 1:2 dan 2:1 serta variasi waktu 30, 60 dan 90 menit kemudian uji parameter COD dan warna. Analisis data variasi dihitung secara kuantitatif, statistik dan ekonomi. Hasil penelitian menunjukan karakteristik awal COD 118.000 mg/L, warna 16.000 Pt-Co, pH 9,2 dan suhu 28,7°C. Efisiensi penyisihan terbaik sebesar 40,7%. Total biaya keseluruhan berdasarkan analisis life cycle cost terbaik adalah Fenton sebesar Rp.12.306.330.000. Berdasarkan hasil penelitian secara mekanisme perlakuan Photo Fenton paling baik dalam mereduksi kadar COD dan warna dalam limbah cair industri pestisida.

Pesticide Industrial Liquid Waste has initial characteristics of COD levels in the range of 100,000 – 200,000 mg/l. This study aims to identify the characteristics of pesticide industrial liquid waste, determine the effectiveness of the Advanced Oxidation Process method and calculate the total cost of industrial-scale AOP. Photo Fenton and Fenton AOP tests of 250 ml of pesticide industrial liquid waste were mixed with FeSO4 and H2O2 with ratio variations of 1:2 and 2:1 and time variations of 30, 60 and 90 minutes then COD and color parameter tests. Analysis of variation data was calculated quantitatively, statistically and economically. The results showed the initial characteristics of COD 118,000 mg/L, color 16,000 Pt-Co, pH 9.2 and temperature 28.7°C. The best removal efficiency was 40.7%. The total cost based on the best life cycle cost analysis was Fenton amounting to Rp. 12,306,330,000. Based on the research results, the Photo-Fenton treatment mechanism is the best at reducing COD and dye levels in pesticide industrial wastewater.
