“…Nilai awal kadar Mn jauh lebih kecil jika dibandingkan dengan kadar awal pada kadar Fe. Terjadinya penurunan kadar besi pada aerasi tray aerator karena adanya kontak antara air dengan udara yang membentuk endapan Fe(OH3) (Joko & Rachmawati, 2016). Hasil di atas menunjukan terjadi penurunan sesuai dengan reaksi aerasi seperti:…”

The problem that is often found in water well is the high content of iron (Fe) and manganese (Mn). This study aims to decrase the content of Fe and Mn in water well with aeration and filtration systems. Aeration used is a multilevel tray aerator by using a tray within 50 cm, while the filtration media used are activated carbon and zeolite sand with a height of 70 cm each. The results showed that the aeration process with tray aerator was able to reduce Fe levels up to 98.34% and Mn reached 97.40%. In the filtration process with activated carbon can reduce Fe levels by 98.48% and Mn by 98.25%. In the filtration process with zeolite sand media can reduce Fe levels by 98.43% and Mn by 97.44%.

“…Baik hidroksida besi (valensi 2) maupun hidroksida mangan (valensi 2) masih mempunyai kelarutan yang cukup besar (Asmadi dkk, 2011). Semakin bertambahnya waktu injeksi udara ke dalam air baku akan semakin memaksimalkan terjadinya kontak air dengan udara sehingga oksigen terlarut akan semakin banyak (Joko dan Rachmawati, 2016). Asmadi dkk (2011) mengatakan untuk mengoksidasi setiap 1 mg/l kadar besi (Fe) dibutuhkan 0,14 mg/l oksigen dan setiap 1 mg/l mangan (Mn) dibutuhkan 0,29 mg/l.…”

Groundwater if allowed to form a yellow precipitate indicates that contains high levels of Fe and Mn are high, so we need a method that is good in quality and economical way to improve the quality of groundwater. Experimental research that aims to determine the effect of aeration is terraced with a combination of sand, activated carbon and zeolite filter. Examination of the samples is done continuous sampling every 1 hour within 5 hours of the treatment 1 (aeration 2 levels followed by a sand, activated carbon, and zeolite filter), the treatment 2 (aeration 2 levels with a combination of zeolite followed by a sand, activated carbon, and zeolite filter), and the treatment 3 (sand, activated carbon, and zeolite filter). The best decreased levels of Fe is to use the treatment 1 with an efficiency decrease of 47,22 %. Whereas decreased levels of Mn best is on each treatment with the efficiency of a decrease of 100 %. Statistical analysis showed that there are differences in the levels of Fe in the tool 1, tool 2 and the tool 3 p (0.028 < 0.05). There is no difference in the levels of Mn on treatment 1, treatment 2, and treatment 3 p (0146 > 0.05).Keywords : Groundwater, Fe, Mn, Multilevel aeration, Sand activated carbon zeolite filterAbstrakAir tanah yang jika dibiarkan membentuk endapan kuning menunjukkan bahwa masih mengandung kadar Fe dan Mn yang tinggi, sehingga diperlukan suatu metode yang baik dalam kualitas dan ekonomis untuk meningkatkan kualitas air tanah. Penelitian yang bersifat eksperimen ini bertujuan untuk mengetahui pengaruh aerasi bertingkat dengan kombinasi saringan pasir, karbon aktif dan zeolit. Pemeriksaan sampel dilakukan secara continuous sampling setiap 1 jam sekali dalam 5 jam pada alat 1 (aerasi 2 tingkat dilanjutkan dengan saringan pasir, karbon aktif, dan zeolit), alat 2 (aerasi 2 tingkat dengan kombinasi zeolit dilanjutkan dengan saringan pasir, karbon aktif, dan zeolit), dan alat 3 (saringan pasir, karbon aktif, dan zeolit). Penurunan kadar Fe yang tertinggi ialah menggunakan alat 1 dengan efisiensi penurunan sebesar 47,22 %. Sedangkan penurunan kadar Mn yang terdapat pada setiap alat dengan efisiensi penurunan sebesar 100 %. Hasil uji statistik menunjukkan bahwa ada perbedaan konsentrasi Fe pada alat 1, alat 2 dan alat 3 p (0.028 < 0.05). Tidak ada perbedaan konsentrasi Mn pada alat 1, alat 2 dan alat 3 p (0.146 > 0.05).

“…The effectiveness of aeration in reducing COD levels can be increased by adding an adsorbent contact medium (Joko & Rachmawati, 2016). Based on previous research, many have used tray aerators to treat laundry's wastewater, but manganese using manganese has not been found in previous studies though manganese can reduce COD.…”

COD level of Pojok Laundry’s wastewater did not meet the quality standard regulated in the Special Region of Yogyakarta Regulation No. 7 of 2016 (>150 mg/l) which was 442.5mg/l. This study was aimed to decrease COD levels using the tray aerator method. Manganese greensand with a diameter of 0.25 mm and a thickness of 2.4 cm/tray was also added. This type of research was a quasi-experimental with Nonequivalent Control Group Design. The sample in this study amounted to 50 samples with 5 treatments (30, 45, 60, 75, and 90 minutes), and 5 repetitions. Samples were taken from the washing machine outlet pipe. There were two groups, where the control group was only given aeration and the treatment group was given aeration with the addition of manganese greensand. Data analysis using the two-way ANOVA test showed that there was an effect of time variations on the decrease in COD levels (p<0.05), there was a difference in the average of decreased levels of COD between the control and treatment groups (p<0.05). The average decrease in COD levels after treatment with a time of 30, 45, 60, 75, and 90 minutes, respectively, was 195.7 mg/l (28.80%); 299.0 mg/l (43.63%); 372.1 mg/l (54.79%); 438.3 mg/l (64.61%); and 513.8 mg/l (75.45%). The decrease in COD levels increased with time. The conclusion of this research was that tray aerator with manganese greensand addition can reduce COD levels with the highest reduction up to 76.69% (90 minutes treatment, detergent usage: 30 g).
