Abstract
Inventia se refera la un procedeu continuu de purificare a apei de nutriti si poate fi utilizata inprocesul de purificare a apelor de suprafata si din puturi la statiile de potabilizare sau in filtrele individuale de tratare a apei. Procedeul solicitat include filtrarea apei prin carbune activ granulat AG-5 si aerarea ei cu un debit de aer de 0,7…0,8 L/ora la 100 g de carbune activ. Noutatea inventiei consta in aceea ca filtrarea si aerarea apei se efectueaza separat. Totodata, initial se efectueaza aerarea apei, dupa care urmeaza filtrarea ei cu o viteza de trecere printr-un strat de adsorbant de 50…60 mL/min.The invention relates to a continuous process of purifying the water of nutrients and can be used in the process of purifying surface waters and from wells at drinking water stations or in individual water treatment filters. The requested process includes filtering the water through AG-5 granulated activated carbon and aerating it with an air flow rate of 0.7 ... 0.8 L / hour per 100 g of activated carbon. The novelty of the invention consists in that the water filtration and aeration is performed separately. At the same time, the aeration of the water is initially carried out, after which it is filtered at a rate of passage through an adsorbent layer of 50 ... 60 mL / min.
