high rejection industrial
Salt rejection up to 99.7% and feed water salinity up to 8000 mg/l
For uncompromising quality permeate
These membrane elements are particularly suited to industrial applications where high product quality is essential or where the feed water contains dissolved salts in the range of 2000-8000 mg/l
- process pure water manufacture
- ultra pure water for semiconductor foundries
- power station demin. plant feed
- pure water production for laboratories
- pure water production for window cleaning
- drinking water production from brackish water sources
