Lead removal

Lead removal

Lead removal

(OP)
A bit general I know, but I'm looking for technologies for the removal of lead from drinking water. I'm waiting on source data / client treated standard, but would appreciate some initial thoughts!

Note this is purely removal techniques, rather than keeping lead piping in state.

Thanks

RE: Lead removal

There are several technologies - how they are applied differes, depending on the intent or process being used. You note freswater - but where and how depends on the source of the freshwater and the other pollutants/organics it contains.
Ozonation is one, normally following filtration of any organics, electrolytic oxidation is another, normally used prior to any R/O or ultrfine filtration - especially if the water contains high levels of fluoride and silica/silicates.

Carbon can be used, zeolite can be used, and some mixed anionic/cationic medias can be used also - again, the main issue is what else the water contains, and at what step it makes economic sense to treat for lead removal.
