| Abstract | ||||
| Ground water is considered an important source of drinking water but in many cases it contains manganese with concentration higher than the standards limits. Therefore purification of ground water is necessary to be adopt to drinking water standards. The scientific research is increased in filtration processes but a little of them has been changed the conventional media as sand and anthracite to other filtration media. This research studies using polystyrene bead as a filtration media to remove manganese from ground water. Since the density of this media less than water density that is called floating media filters. This media has some advantages over conventional media in many things as it wants a little quantity of washing water (around 1%) of filter product, doesn't need separate washing pumps that because the washing process is in the same direction of gravity. The experimental work was designed and run in the laboratory of Sanitary Engineering, Faculty of engineering – Mansoura University to study the possibility of using polystyrene beads as filtering media to remove manganese from ground water. Synthetic water was used having manganese concentration from 0.50 to 4.50 mg/l and was oxidized by sodium hypochlorite and then passed it through filtration column with velocities ranged from 3.0 to 5.0 m/hr. The conducted study cleared that the using of expanded polystyrene beads as filtering media to remove manganese from ground water was successful. The average removing manganese percentage was 85.48% and turbidity removal with 76.16%. | ||||
