Groundwater Processing Equipment into Clean Water with a CombinationProcess of Aeration-Upflow Filtration (a Design). In areas that have not received clean water services, residents usually use well water, river water which sometimes even often the water used does not meet the standards of healthy clean water. To treat well water/ ground water is usually the community. build a processing unit in the form of a sand filter. The problem that is often encountered in treatment is cleaning the filter media. This condition is often difficult for the community to do because it requires time and energy, resulting in the sand filter that is supposed to be operational continuously and finally stops and is not even used at all. To overcome this problem, it can be done by improving the design of water treatment units with a system of combination of aeration and upflow flow filtration. This study is to determine the ability of the tool to improve the quality of shallow groundwater in terms of turbidity, Fe, Mn, color and odor to clean water and saturation point of filtering. Research Design is a "quasi-experiment" in the form of "Time Series Design" using a "pre and post test" design without control. The tool is designed in the form of an application prototype to determine its ability to reduce turbidity, Fe, Mn, color and odor and the length of saturation point. The results showed that iron content before processing 2.12 after processing 2,058. pre-treatment manganese content 0.080 after processing 0.078. Color and smell before color processing and odor after processing are colorless and odorless. Microbiological quality for stool coly before processing week 1 32 after treatment 0, week 2 coly of feces before processing 26 after processing 0 and weeks 3 coly of feces before processing 21 and after processing 0. Length of processing up to saturation point filter media total contact time processing is 30 minutes. Bangun). Untuk mengolah air sumur/air tanah biasanya masyarakat membangun unit pengolahan berupa saringan pasir. Masalah yang sering ditemui dalam perawatan adalah pembersihan media saring. Kondisi ini sering sulit dilakukan oleh masyarakat karena membutuhkan waktu dan tenaga sehingga mengakibatkan saringan pasir yang seharusnya beroperasional secara terus menerus akhirnya terhenti dan bahkan tidak digunakan lagi. Untuk menanggulangi masalah tersebut, dapat dilakukan dengan cara memperbaiki rancang bangun unit pengolahan air dengan sistem kombinasi aerasi dan filtrasi aliran ke atas (upflow). Tujuan penelitian mengetahui kemampuan alat dalam memperbaiki kualitas air tanah dangkal dari segi kekeruhan, Fe, Mn, warna dan bau menjadi air bersih serta titik jenuh penyaringan. Desain penelitian"eksperimen semu" berupa "Time Series Design" menggunakan rancangan "pre and post-test" tanpa kontrol. Alat dirancang berupa prototype secara aplikatif guna mengetahui kemampuannya dalam menurunkan kekeruhan, kadar Fe, Mn, warna dan bau serta lamanya titik jenuh. Hasil penelitian menunjukkan bahwa kadar zat besi besi sebelum pengolahan...
Air sungai yang keruh dapat mengandung zat besi atau mangan dan bakteri E.Coli jika dikonsumsi manusia akan dapat menyebabkan gangguan kesehatan dan penyakit seperti : Cholera, disentri , Tifus dan diare. Penelitian ini bertujuan untuk mengetahui kemampuan alat pengolahan air dengan pompa aerator dan saringan spons untuk menghasilkan air bersih yang memenuhi syarat kesehatan (Kekeruhan,warna,pH, zat besi (Fe), mangan (Mn) dan Total Hardnes (CaCO3). Jenis penelitian ini adalah eksperimental, dengan desain pre and postes control study”. Sampel air diambil dari sungai Deli Medan sebanyak 500 liter. Pengumpulan data dilakukan dengan mengukur kadar awal dan akhir sebelum (Pre-test) dan setelah uji coba alat (Post-test) terhadap kekeruhan, warna,pH, zat besi (Fe), mangan (Mn) dan Total Hardnes (CaCO3) sampel air sungai. Alat pengolah air terdiri dari 2 buah bak plastik volume 250 liter untuk wadah air sampel dan 2 buah drum plastik volume 40 liter untuk saringan spons dan 2 buah mesin blower serta 2 unit tempat penyangga drum plastik wadah sampel dan saringan saringan spons. Replikasi uji coba alat dilakukan sampai 3 (tiga) kali pengulangan. Pengolahan data dilakukan secara manual, data disajikan dalam bentuk tabel frekuensi dan narasi.Analisa data dilakukan secara diskriptif. Hasil penelitian diperoleh bahwa kualitas fisik air bersih untuk parameter warna rata-rata 4,9 TCU (memenuhi syarat) pada keceatan aliran 60 liter/jam, dan parameter kekeruhan tidak memenuhi syarat ( 40 mg/l); Kualitas kimia yang memenuhi syarat adalah pH = 6,8 dan Mn = 0,46 mg/l, parameter CaCO3 = 99,7 mg/l masih dibawah standar sedangkan yang tidak memenuhi syarat yaitu parameter Fe = 1,28 mg/l. Alat pengolah air sungai dengan aerator dan saringan spons dapat digunakan untuk mengolah air yang mengandung Mn dan CaCO3, dan Perlu penelitian lanjutan dengan variasi waktu aerasi > 15 menit dan waktu pengendapan > 30 menit.
Vehicle washing business services in the current era are growing in numbers, both simple and those that have used technology. As a consequence, the production of wastewater more and more, which if not controlled will have an impact on environmental pollution. Conventional wastewater treatment technology is sometimes less effective because it requires chemicals in the process and requires relatively longer, so the need for land to build a treatment unit is relatively wider. To provide an alternative treatment process that is simpler and has good results and does not require large tracts of land, it is necessary to develop electro-coagulation technology combined with flotation. Electrocoagulation is the process of clumping and precipitation of fine particles contained in water by using electrical energy. This study was to determine the ability of electrocoagulation-flotation technology in decreasing the parameters of COD, detergents, and oil in motor vehicle washing wastewater based on the type of electrodes used at 12 and 24-volt electric voltages with contact times of 30 and 60 minutes. This study is an experimental study with a "pre and post-test group design" design. The results showed that the combination of electrocoagulation-flotation at 24-volt voltage and 60 minutes contact time with aluminum electrodes could reduce COD 82.7%, oil 46.5%, and detergent 68.9%. Whereas with iron electrodes the COD decreased by 81.1%, oil by 43.7% and detergents by 65.1%. With an average reduction, aluminum electrodes are better than iron electrodes. Although aluminum and iron electrodes are better, statistically the two are not different (p <0.05), this shows that there is no difference in the ability to decrease test parameters. Other than that, the longer the contact time, the greater the decrease in test parameters. The conclusion is that the electrocoagulation-flotation combination method can be used to reduce the COD, oil/fat and detergent parameters in motor vehicle washing wastewater. The results of this study are expected to be applied to motor vehicle washing activities by utilizing iron waste as an electrode.
Cabbage is the third largest commodity in North Sumatra after chili and tomatoes. in 2015 which was 70,730 tons, in 2016 the amount of cabbage production was 92,551 tons and in 2017 the amount of cabbage production was 98,325 tons, it can be seen that the trend is increasing every year. Cabbage waste that is wasted and not utilized can cause pollution and environmental pollution
