  • Advanced Oxidation Processes (AOPs) method has been applied and is growing in number of textile wastewater treatment. Textile industries are commonly using synthetic dyes in the dyeing process and will produce coloured-wastewater that is still contain of organic compound and is hard to be degraded. One of most frequently used synthetic dyes in textile industries is direct dyes. Direct dyes wastewater consists of azo bound whereby difficult to eliminate the colour and the concentration itself, thus an appropriate treatment such as AOPs is considered. The AOPs process to degrade direct dyes wastewater in this research uses a combination of H2O2 with catalyst MnO2. Parameter variation that carried out, are the variation of the ratio of wastewater and H2O2 volume, namely 1:1; 2:1 and 1:2. Whilst the using of mass of catalyst MnO2 is 1 g for each sample variation, namely 1 g for 250 ml and 500 ml H2O2. The results obtained after the BOD, COD and pH tests, are 230 mg/l, 784 mg/l and 5,26 respectively. This result is showed by the sample with variation 2:1 which is delivering the lowest values of BOD, COD and pH amongst the three sample variations mentioned
  • ABSTRAK: Metode AOPs (Advanced Oxidation Processes) telah banyak digunakan dan semakin berkembang untuk diaplikasikan pada pengolahan limbah tekstil. Perusahaan tekstil biasanya menggunakan zat warna sintetis dan menghasilkan limbah berwarna yang masih mengandung senyawa organik dan sulit untuk didegradasi. Salah satu zat warna yang paling sering digunakan adalah zat warna direk. Limbah zat warna direk mengandung ikatan azo yang sulit untuk didegradasi sehingga membutuhkan penanganan yang tepat seperti dengan metode AOPs. Proses AOPs untuk mendegradasi zat warna direk pada penelitian ini menggunakan kombinasi larutan H2O2 dengan katalis MnO2. Parameter yang dilakukan antara lain variasi perbandingan volume limbah dengan larutan H2O2 50% yaitu 1:1; 2:1 dan 1:2. Sedangkan massa MnO2 yang digunakan adalah 1 g untuk setiap variasi perbandingan yang dilakukan, yaitu 1 g untuk 250 ml dan 500 ml larutan H2O2. Setelah dilakukan pengujian dengan parameter BOD, COD dan pH diperoleh hasil BOD, COD dan pH terendah pada sampel percobaan dengan variasi 2:1, yaitu sebesar 230 mg/l, 784 mg/l dan 5,26.Kata Kunci: AOPs; degradasi; H2O2/MnO2; limbah tekstil; zat warna direk ABSTRACT: Advanced Oxidation Processes (AOPs) method has been applied and is growing in number of textile wastewater treatment.
