  • Flocculation of Cu, Zn, Pb, Ni and Mn during mixing River Water with Caspian Seawater

    Rivers are the major transporting means for dissolved and particulate matter from the continents into the seas and lakes (Meybeck, 1988). Dissolved metals come into the particulate phase due to flocculation processes during estuarine mixing (Eckert and Sholkovitz, 1976; Sholkovitz, et al., 1977 and Boyle, et al., 1977). Many investigations have been carried out on ...

  • The Whole Plant Approach to Air Emission Modeling for NESHAP Compliance

    ABSTRACTLong overlooked, the air emissions associated with biological treatment of process wastewaters continue to be further scrutinized and regulated. The common approach is to utilize EPA’s Water9 as a model to present findings and support permitting activities. It is essential when using a model that not only is the facility modeled appropriately, but also that the specific compound ...

  • Silent sentinel role for static gas analyser at United Utilities

    Biogas produced by the United Utilities anaerobic digestion sludge plant at Lancaster (Stodday) waste water-treatment runs a brand new 525kW combined heat and power (CHP) engine generating electricity and now operating 24/7. It joins an existing 325kW engine already in service for three years. In addition to biogas from the Stodday mesophilic anaerobic digester, a new enzymic hydrolyser increases ...
