ultra low pressure
less than 10 bar operation and 99.5% rejection
For energy saving and high productivity
For an unbeatable quality permeate under ultra low pressure operating conditions these membranes elements are difficult to beat. A drinking water compliant membrane particularly suitable for:
- process pure water manufacture
- boiler feed water manufacture
- power station demin plant feed
- nitrate removal from drinking water supplies
- pure water production for laboratories
- pure water production for window cleaning
