Abstract: Tracer studies are conducted to characterize the hydraulic behavior of upflow anaerobic filters at Reynold's numbers less than 25. Tests are conducted with three different sizes of cross‐flow modular plastic media, providing ...

Abstract: The dilution method has been accepted widely as the standard procedure for determining biochemical oxygen demand (BOD). A mass-balance approach was used to analyze four equations for computing BOD: two involving external ...

Abstract: Ballasted flocculation processes were studied at laboratory scale to evaluate the mode of transport of ballasting agent from bulk liquid into the chemical floc and establish a new model for assessing the mechanisms of ...
