OSMO* BEV NF Series
Beverage and Bottled Water Production
The OSMO* BEV NF membrane element is engi-
neered to provide beverage plants with consistent,
high quality water for production of carbonated soft
drinks, juices, and sport drinks. The OSMO BEV NF
element will process most municipal or plant well-
water to meet your alkalinity, hardness and low so-
dium requirements. The OSMO BEV NF membrane
element is chlorine tolerant, and offers a salt pas-
sage profile that permits maximum water recovery
by the NF.
The OSMO BEV NF membrane element is tested and
certified by NSF International against NSF/ANSI
Standard 61 for material requirements only.
Features include a Full-Fit* design that eliminates
the stagnant zone associated with industrial FRP
elements and their brine seals, which can act as a
site for bacterial growth. The OSMO BEV NF element
forms a flush-fit with the inner diameter of the
membrane element housing, creating a self-
cleaning effect. This design also offers less pressure
resistance than an industrial FRP element, resulting
in lower brake horsepower and substantial energy
savings.
The OSMO BEV NF membrane is following a 100%
Wet Test Quality Assurance.
