actuators offered by Festo,” reports Dr.
Ivan Znamensky, Festo Sales Manager for
the European part of Russia. A pneumatic
system with actuators DAPS, including
two air compressors, required an installed
load of only 10 kW. “Simply by replacing
the electric actuators with 120 pneumatic
actuators, we were able to save at least
an additional 65,000 euros,” says water
expert Perschin delightedly.
Ready-to-install solutions
The new block K-6 of the Surface Water
Treatment Plant South in St. Petersburg
includes 20 new sand bed filters. Each
filter tank is assigned six units with
actuators and shut-off valves to open
and close the inlets and outlets.
In addition to units consisting of
actuators, shut-off valves and sensor
boxes, which Festo supplied ready to
install, Vodokanal has chosen ready to
install control cabinets with valve
terminals VTSA, pressure and flow
sensors and service units from Festo’s
MS series. “If we source all the pneumatic

same supplier, we simply have fewer
problems during operation and
maintenance,” says Perschin, “because
Festo’s experts are always there when
we need them.”
The new block K-6 of the water
treatment plant, the most modern in
the whole of Russia, is equipped with a
central control system at the process
control level and allows comprehensive
monitoring of the water treatment
process. The control system gathers
current data and compares this
continuously with defined setpoints. The
automation technology from Festo is fully
integrated into this monitoring process
and uses sensor signals to supply up to
date information on the operating status
of individual plant sections.
Water for a boom town
St. Petersburg and the capital Moscow
are Russia’s two boom towns. The city is
still growing, with constant new housing
developments and industrial zones.
Vodokanal supplies 4.8 million people with
1.9 million cubic metres of drinking water
every day. Block K-6 of the water treatment
plant alone provides 350,000 cubic metres
of drinking water and conforms to the
highest modern standards as regards filter
technology and chemical treatment
with ozone. The pneumatic automation
technology installed in block K-6 also
allowed the water utility company
to achieve a quantum leap in energy
efficiency.
