  • Degradation of wine industry wastewaters by photocatalytic advanced oxidation

    ABSTRACTWine industry wastewaters contain a high concentration of organic biodegradable compounds as well as a great amount of suspended solids. These waters are difficult to treat by conventional biological processes because they are seasonal and a great flow variation exists. Photocatalytic advanced oxidation is a promising technology for waters containing high amounts of organic matter. In ...

  • Treatment of textile effluent using Advanced Oxidation Process and Nanofiltration

    Textile effluent containing two dyes, Cibacron Red (CR) and Cibacron Black (CB) and NaCl was treated using advanced oxidation process and nanofiltration. In Scheme 1, advanced oxidation was followed by NF and in Scheme 2, two-step NF was employed. In Scheme 1, dye concentrations fell below 1 mg/l. In Scheme 2, two-step NF results in permeate concentration less than 1 mg/l of dyes. Salt recovery ...
