Catering for clean water
AUMA's high-performance electric valve
actuators prove their performance in
industrial water treatment
ith more than 50 years of experience
in supplying reliable and rugged valve
automation solutions, AUMA offers electric
valve actuators that meet the most demanding
requirements for process water
W
and industrial wastewater applications.
" The requirements for industrial wastewater
purification are getting more and
more stringent in many countries, " says
Marc Schmidt, Head of Sales Water at
AUMA. " AUMA actuators are proving their
performance in industrial water treatment
projects around the world, in industries
from pharmaceuticals and chemicals to microelectronics
and mining. They also meet
the challenging requirements of zero liquid
discharge (ZLD) facilities, supporting advanced treatment technologies
such as reverse osmosis (RO). "
A worldwide installed base of several hundred thousand actuators
in water and wastewater treatment confirms the toughness and
reliability of AUMA's flagship SA multi-turn and SQ part-turn actuators.
They feature a robust design, long service life, IP 68 enclosure
protection and maximum corrosion resistance, meeting C5-M and
C5-I requirements according to EN ISO 12944-6. Integral controls
add powerful diagnostics and datalogging, with easy DCS integration
via fieldbus or Industrial Ethernet communication.
Modular design and a wide range of actuator sizes and options
offer automation solutions for any type of valve. Special modulating
duty and variable-speed versions provide maximum positioning accuracy
and high operating speed.
AUMA electric valve
actuators have a
strong background
in industrial water
and wastewater
treatment, including
ZLD facilities.

Treatment of Waste Water
Sludge in Fermenters
(Digesters):
* In large reactor vessels, (>1000 m3)
has to blended viscous sludge with
about 2-8% organic solid content
EKATO EM 2000 / EKATO
AQUAJET B impeller
* Avoid settlement particles at the bottom of the vessel
* Reduction and incorporation of dry solid layers on top of the liquid. The
layer arises due to the drying effect caused by the methane gas flow
out of the liquid surface
* Handling of sludge that is contaminated with long fibers which can agglomerate
at the impeller
The complete agitator can be destroyed due to resulting shaft deflection.
Using the EKATO-Aquajet B does solve this problem.
* The EKATO-EM 2000 agitator series has several mechanical seal
types to handle the explosive conditions
