The biofiltration technique is of great importance for the removal heavy metals. In present work, a laboratory-scale biofilter was modeled using rice husk as filter material. Wolborska model used to know dimensions necessary function. Langmuir and Freundlich isotherms were performed quantify adsorption process, showing that are ones highest correlation coefficient best represent process Cd (II)...

Abstract The study aimed to eliminate the nitrogen and its main residual forms from municipal wastewater by using a biofilter system adapted for small community. biological nitrification/denitrification used involved two successive polyvinyl chloride (PVC) columns; first gravel column (C1) loaded with primary followed second sandy (C2). A complex biofilm development on sand materials has been c...
