The Possibility Of Wastewater Treatment By Some Selective Filtrations

The present study deal with wastewater treatment by four selective filtrations (Sand Filter, Sawdust Filter, Coal Filter, Ceratophyllun demersum l. Filter ) to reduce some physical ,chemical and bacteriological properties of wastewater such as (TS, COD, BOD, pH ,EC,TN, TP, Cd, Cu, Ni, Pb, Zn Fecal coli bacteria) . Samples collected from wastewater treatment station near Al-Nassyria city center - south Iraq .The result showed that selective filtrations specialized Sand Filter reduced these properties above and decrease of pollutant in this study.
