System components for

biological water treatment

nnnn

GVA

nnnn

Based on our innovative system components,

nnnn

we have succeeded in gaining international

nnnn

reputation as a specialist in waste water

nnnn

processing technology, which we continuously

nnnn

assure and extend. Our R&D department work

nnnn

with great innovation commitment to develop,

nnnn

and optimize, our own system components,

nnnn

which are partly patented, in conjunction with

nnnn

process technology and engineering techniques

nnnn

as well as adapt them to new development

nnnn

achievements and methods. In addition, we

nnnn

take into account, of course, the increasingly

nnnn

demanding customer requirements such as

nnnn

first-rate quality, reduced operating costs,

nnnn

serviceability and faster return on investment.

nnnn

For this purpose, GVA's after-sales service also

nnnn

offers corresponding services for plant inspec-

nnnn

tions, machine maintenance, rehabilitation and

nnnn

optimization of equipment and components.

nnnn

WEEDLESS agitators successfully operate

nnnn

already in several hundreds of sewage treatment

nnnn

facilities all over the world

nnnn

Agitators for waste water treatment facilities

nnnn

operate based on a simple principle, but they are

nnnn

of essential importance for the success and

nnnn

continuity of the overall process.

nnnn

This is the reason why high demands are made

nnnn

on the efficiency and longevity of these

nnnn

components. The WEEDLESS agitators of GVA

nnnn

have been especially developed for stringent

nnnn

requirements resulting from permanent load,

nnnn

specific operation conditions and the often very

nnnn

differing composition of communal and industrial

nnnn

waste water.

nnnn

Typical applications of WEEDLESS agitators are:

nnnn

■ Mixing of anaerobic and anoxic zones for

nnnn

biological elimination of phosphates and

nnnn

denitrification

nnnn

■ Application in mixing and balancing basins

nnnn

■ Pressure aeration with separate circulation

nnnn

GVA agitators prove their high quality day by day

nnnn

in hundreds of waster water treatment facilities.

nnnn

Being a system specialist in these technologies,

nnnn

GVA delivers not only components and process

nnnn

know-how, but its business operations also

nnnn

include sewage plant planning and consultation

nnnn

for sewage plant operators worldwide.
