Abstract

Air yang mengandung Fe harus diturunkan kandungannya dengan cara oksidasi, salah satunya aerasi. Proses oksidasi dilakukan agar senyawa Fe mudah mengendap. Dalam studi ini, metode yang digunakan adalah studi literatur, percobaan aerator dan penelitian di laboratorium, serta desain aerator itu sendiri. Aerator yang digunakan adalah tray aerator dan cascade aerator dengan variasi jumlah konsentrasi besi dalam larutan sampel. Parameter yang diukur meliputi nilai DO, konsentrasi Fe dan Mn dalam air, temperatur, serta pH air. Hasil penelitian menunjukkan bahwa tray aerator lebih baik dari cascade aerator dengan efisiensi penyisihan pada tray aerator sebesar 2% hingga 8%, sedangkan pada cascade aerator sebesar 1% hingga 8%. Begitu pula dengan penyisihan mangan, pada tray aerator sebesar 10% dan pada cascade aerator sebesar 9%. Nilai KLa pada tray aerator juga lebih tinggi, yaitu 0,0820/menit dibandingkan dengan cascade aerator sebesar 0,0799/menit. Dengan demikian, dapat diambil kesimpulan bahwa tray aerator lebih baik karena memiliki nilai KLa dan efisiensi penyisihan Fe dan Mn lebih tinggi dibandingkan dengan cascade aerator.

Water containing Fe must be reduced by oxidation, one of which is aeration. The oxidation process was carried out so that the Fe compounds easily precipitated. In this study, the methods used were literature study, aerator experiments and laboratory research, as well as the aerator design itself. The aerators used are tray aerator and cascade aerator with variations in the amount of iron concentration in the sample solution. Parameters measured included DO values, Fe and Mn concentrations in water, temperature, and water pH. The results showed that the tray aerator is better than the cascade aerator with a removal efficiency of 2% to 8% for the tray aerator, while for the cascade aerator it is 1% to 8%. Likewise with the removal of manganese, the tray aerator is 10% and the cascade aerator is 9%. The KLa value on the tray aerator is also higher, namely 0.0820/minute compared to the cascade aerator of 0.0799/minute. Thus, it can be concluded that the tray aerator is better because it has a higher KLa value and removal efficiency of Fe and Mn compared to the cascade aerator.
