Water, Sewage & Effluent Mar Vol 30 No 2 | Page 37

Economic necessities dictate
the course of the international
water and sewage industry
and at the IFAT trade fair, to
take place in Munich from
May 30 until June 3, how the
environmental technology
sector is responding to the latest
challenges will be showcased.
Stricter sewage guidelines,
rapid population growth and
bottlenecks in the water supply
mean that the market for
membrane bioreactors (MBR)
is growing more quickly. The
membrane growth procedure
allowing water to be reused
is gaining in importance,
particularly in urban areas.
For years, the VRM rotating
membrane filtration system from
the mechanical engineering
company Huber has been used
in municipal and industrial MBR
processes. In partnership with
the Wiesbaden-based membrane
and module manufacturer
Microdyn-Nadir, the system has
been redesigned. The aim was
to combine the benefits of the
rotating membrane system with
those of proven Bio-Cel module
technology. High throughputs
of up to 250m³/h and above all
energy-efficient, highly effective
membrane cleaning with less
than 150l/m²h of flushing air
are among the key benefits.
As the manufacturer’s data
shows, the Bio-Cel modules
also offer a long operating life,
can be cleaned at low cost and,
as ultrafiltration membranes,
ensure good drainage. According
to Huber, this means not only
high-performance, reliable
system operation but also low
specific investment, operating
and energy costs. Huber will
install the new membrane
filtration system in full size as
a highlight at its IFAT stand.
Inge's multi-bore membrane
is another well-established
product. In the field of water
treatment, the very smallpored filters reliably trap not
only particles but also microorganisms such as bacteria or
viruses. Along with specialist
colleagues from BASF, the
company's team has improved
