CUT Membrane Technology
Tubular membrane modules
for recycling pickling acids
With cross-flow microfiltration, suspended
particles can be removed from
pickling acid effectively. Due to their
high resistance against acids, caustics
and abrasive metal particles, the
T-CUT tubular modules (photo) are
particularly suitable for this application.
The symmetric tubular membranes are
constructed from polypropylene (PP),
offering
resistance against abrasion,
BinMaster
as well as mechanical and chemical
stability. Microfiltration of pickling acids
enables the contaminated liquid to be
concentrated to a factor of up to five,
which means a reduction of waste
volume by the same amount. The remaining
concentrate contains up to
35-40% solids. T-CUT PP modules
ensure a stable permeate flux of about
80 L/(m2.h). The filtration performance
is maintained by backflushing the symmetric
membranes for a few seconds
every 30 min. - CUT Membrane

A powerful radar level sensor
for powders and bulk solids
The NCR-80 non-contact radar level
sensor (photo) for powders and bulk
solids features an 80-GHz frequency
focused in a narrow 4-deg beam
angle, enabling precise aiming to avoid
the flow stream, internal structure or
sidewall buildup. This ensures reliable
performance at measurement ranges
up to 393 ft and accuracy within 0.2
in. The NCR-80 is resistant to interference,
and its firmware constantly
tracks echoes and automatically eliminates
false echoes for reliable performance.
The NCR-80 is suitable for
continuous, single-point level measurement
in tall and narrow vessels
where there is excessive noise or dust.
Mounting the instrument is simple,
due to the availability of 0- and 30-deg
mounting plates for slanted roofs and
10- and 8-deg swiveling holders with
directional aiming. A variety of flange
sizes and adapter flanges are available.
