Abstract
Invenţia se referă la procedee de purificare a apelor de profunzime de ioni de amoniu, amoniac şi hidrogen sulfurat.Procedeul, conform invenţiei, include tratarea apei cu hipoclorit de calciu în raport de 1…5 g la 5 litri de apă, la temperatura de 15°C, malaxarea timp de 30 min şi ajustarea ulterioară a pH-ului până la 5,28…8,0, sedimentarea carbonatului de calciu format timp de 30 min, după care stratul de apă limpede se filtrează printr-o coloană cu cărbune activ AG-3 la viteza de 8 m/oră.
