Abstract: A coupled biological fluidized bed system, operated in the pre‐denitrification mode, was used to evaluate its potential in implementing nitrogen removal from raw and diluted coking plant wastewaters and coal liquefaction ...

Abstract: Models incorporating liquid-gas mass-transfer and biofilm mass-transfer resistances were developed for trickling filters (TF) and rotating biological contractors (RBC). Biodegradation and volatilization coefficients were ...

Abstract: A study of the fate of volatile organic contaminants (VOCs) in trickling filters (TF) and rotating biological contactors (RBC) was performed. Of the target compounds investigated, tetrachloroethylene was volatilized to the ...

Abstract: A model was developed for predicting the fate of metals in municipal wastewater treatment. The model, which incorporates metal solubility and sorption onto solids, was calibrated with experimental data obtained by a titration ...
