  • Assessing performance of on-line nitrate analyzers

    Traditionally, activated sludge processes were designed to remove organics and suspended solids from wastewater. The justification for including nitrogen control in wastewater treatment facilities began with the need to protect receiving waters from the increasing problem of eutrophication and hypoxia (low levels of dissolved oxygen in bottom waters, generally less than 2 mg/l). One of the ...
