Air bersih merupakan kebutuhan primer bagi manusia. Tidak seimbangnya ketersediaan air bersih dengan pesatnya pertumbuhan penduduk menimbulkan dampak pada pendistribusian air bersih yang tidak merata. Kondisi tersebut membuat masyarakat mencari sumber air bersih lain seperti air sumur. Air sumur sebagai alternatif air bersih sering didapati mengandung besi (Fe) dan (Mn). Kandungan Fe dapat menyebabkan gangguan kesehatan seperti rasa mual ketika dikonsumsi, rusaknya dinding usus dan iritasi pada mata dan kulit. Sementara kandungan Mn yang diatas baku mutu dapat menyebabkan gangguan pada pembuluh vaskuler, jantung dan sistem saraf. Multiple tray aerator piramida adalah aerasi dengan menggunakan susunan nampan yang tidak membutuhkan lahan yang luas serta memiliki efisiensi tinggi. Penelitian ini menggunakan variasi jumlah tingkatan tray (1 tingkatan, 2 tingkatan, 3 tingkatan, 4 tingkatan dan 5 tingkatan) dan waktu aerasi (15 menit, 30 menit, 45 menit, 60 menit dan 75 menit) untuk mengetahui pengaruh terhadap penurunan kadar Fe dan Mn serta menemukan tingkatan dan waktu paling efektif. Hasil penelitian menunjukkan multiple tray aerator tingkat 4 dengan waktu aerasi selama 75 menit memiliki efektifitas tertinggi sebesar 83.39% untuk besi dan 98.14% untuk mangan.

Organic waste is the waste residue of a material that has been thrown away, but its existence can still be utilized. So far, organic waste from traditional markets is directly disposed of in landfills. Even though organic waste if left uncontrol cause unpleasant odors, it can also cause environmental pollution because organic waste can be destroyed by itself so that it will absorb into the soil which can cause pollution to groundwater infiltration. Nutrients contained in traditional market waste can be combined with animal manure that is cow manure and chicken manure, so this research will produce alternative biogas energy, it can be used in daily life. The decomposition of organic matter with a fermentation process by microorganisms on the material which takes place anaerobically to produce methane. This study uses a variety of ingredients that have been determined to find the maximum concentration with the best results.
