The efficiency of contaminated water treatment by using Nano_colloidal silver technique

Abstract

This work investigates natural antibiotic material for drinking water by using nano_ colloidal silver technique. The nano colloidal silver suspension (CSS) prepared using electrochemical method and characterized physically. The efficiency of bacterial treatment of Dyala river water and Tigris river water from the side of Gherai’t using nano- colloidal silver suspension was studied. The silver concentration as antibacterial agent was examined for water samplestook from different sides of Dyala River. The results of these tests show that good activity can be obtained of nano-collidal silver as new purification technique for contaminated water.
