<br/><br/> This work has been carried out to determine the levels of lead and mercury in drinking and industrial wastewater of acid and dry battery factories , Cairo - EgyptThe removal of lead and mercury from industrial wastewater were carried out through two methods , chemical and biological treatmentThe chemical treatment , based on the addition of ferrous sulfate (as Fe2+ions) and the alkalization of the medium by (6N) NaOH to form ferrous hydroxide and partial oxidation of Fe2+to Fe3+by air to form ferrite sludge and the subsequent adsorption / coprecipitation of lead and mercury from wastewaterWe discussed the effect of control factors (pH , time , temperature , air pressure and the ratio of Fe (II) / Total metals concentration) on the removal of lead and mercuryMaximum removal of lead (99975
