Ready-to-install control cabinet solution:
The valve terminal VTSA with a service unit from
the MS series ensures reliable operating cycles in
the Vodokanal water treatment plant K-6.
Pneumatic actuators in various sizes: These
ensure reliable opening and closing of the
sand-bed filters for the inlet and backwashing.
Pre-assembled units: 120 pneumatic actuators
DAPS with sensor boxes open and close
the shut-off valves for the 20 sand-bed filters.
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 actu­
ators, 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 automation
equipment we need from the same
supplier, we simply have fewer problems
during operation and maintenance,” says
Perschin, “because Festo’s experts
are always there when we need them.”

Area of business:
Treatment of drinking water and
wastewater for St. Petersburg
“Pneumatics makes it
easy to save energy in
a water treatment plant.”
Dr. Ivan Znamensky, Sales Manager at Festo for European Russia
The new block K-6 of the water treat-
ment 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 pro-
cess. 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.
