relation to the chemicals contained
in drinking water.
Based on its long-standing experience
and extensive know-how, and employ-
ing innovative process techniques,
Bauer Water has committed itself to
safeguarding public access to fresh
water at the highest level. The portfo-
lio extends from compact treatment
plants for emerging countries – to
cope with the new burdens they face
arising from extensive agricultural
use – and for disaster relief missions
through to turnkey drinking water
works for local communities. Along-
side standardized products, Bauer
Water offers custom solutions adapt-
ed to specific requirements. At the
heart of many treatment plants, featur-
ing in a wide variety of different proj-
ects, is membrane technology. The
plants are modular in design, and can
be supplied in a variety of size options.

concerned. Low electrical conductivity,
zero oxygen content and softness are
some characteristics of process water.
As the process water required is usu-
ally obtained from groundwater or
mains water, it must be treated appro-
priately before being fed into boilers,
used for cooling, turned into ultra-pure
water or used in the manufacture of
products. Employing a range of chem-
ical/physical, biological and technical
processes, Bauer Water is able to
meet any customer requirements with
tailored solutions, thereby also help-
ing to cut the actual consumption of
process water. Bauer Water offers its
industrial customers a package which
encompasses consulting, engineering
and service, through to financing. A
particular strength of Bauer Water is

terms – a fact long overlooked during
the era of industrialization.
Over recent decades, however, a
range of processes have been devel-
oped to recover and re-use process
water. Many industrial plants now re-
cycle the water they need to run; the
"closed circuit" in relation to water is
state of the art. The wide variety of
processes employed in the various
industrial fields also means that differ-
ent types of waste water, with specific
pollutant contents, are produced. Usu-
ally this water has to be pre-treated
before being allowed to enter public
treatment plants, or it is definitively
treated before being routed into an
outfall. Ideally, process water can be
re-treated and returned to the produc-
tion operation. In some cases it is also
possible to extract raw materials from
the waste water, such as from fermen-
tation residues and production waste.

Bauer Water has set itself the goal of
becoming a leading vendor of custom
complete solutions which are advanced
in design, fit for the future, sustainable
and economical. Filtration, centrifuga-
tion, flotation and biological processes
are the technologies it is employing to
this end. As a partner to the oil and gas
industry, Bauer Water offers a range of
packages including complete DBOOT
(Design, Build, Operate, Own and
Transfer) solutions. The deployment of
all available technologies enables
substantial oil content to be extracted
from the contaminated water and re-
covered on behalf of the customer.
Moreover, all processes are designed
to further conserve valuable resources
by saving energy. A project unmatched
anywhere in the world is Bauer Nimr
