nitrate nitrogen may be present in

nitrate nitrogen may be present in small amounts in fresh domestic wastewater. however, is seldom found in influens to treatment plants because the nitrate serves as an oxygen sorce in the biologically unstable wastewater. on the other hand, nitrate is often found in the effluents of biological treatment plants,because it represents the final form of nitrogen from the oxidation of organic nitrogen compounds. trickling-filter and activated sludge treatment plant effluents may contain from 0 to 50 mg/L nitrate, depending on the total nitrogen content of the influent, the degree og loading, and the temperature of the sewage

nitrat nitrogen dapat hadir dalam jumlah kecil di limbah domestik yang segar. Namun, ini jarang ditemukan di influens untuk perawatan tanaman karena nitrat berfungsi sebagai sorce oksigen dalam air limbah biologis tidak stabil. di sisi lain, nitrat sering ditemukan di limbah tanaman pengobatan biologis, karena itu merupakan hasil akhir berupa nitrogen dari oksidasi nitrogen organik senyawa. limbah tanaman Lumpur menetes-filter dan diaktifkan pengobatan mungkin berisi dari 0 untuk 50 mg/L nitrat, tergantung pada total nitrogen konten influent, gelar og pemuatan dan suhu limbah
