Evaluation of Various Adsorbents and Coagulants for Waste-Water Renovation

摘要

The study demonstrated the feasibility, at least from a mechanical standpoint, of incorporating solid adsorbents into the sludge blanket process for water treatment in the presence or absence of coagulants. The sludge blanket process can combine the virtues of the finely divided, large-surface-area forms of solids and flocs (normally associated with batch treatment techniques or vacuum filtrations) with the maintenance of relatively high flow rates, normally associated with columnar-bed techniques. Material cost factors are discussed for the various materials tested and for the treatments involving their use. Recommendations are made for possible further lines of investigation. (Author)
