|Euroby completes the
commissioning of two Flottweg C5E decanter centrifuges at
Dwr Cymrus Ponsticill Water Treatment Plant.
|Flottweg AGs superb C
range of decanter centrifuges are tasked with dewatering
sludge from an upland reservoir water treatment plant. They
were installed to replace two existing centrifuges which
were underperforming and to accommodate an increase in
|Capable of throughputs between 10 and 90m3
of sludge per hour, shortly to increase further, the C range
is specifically designed for municipal and potable sludges.
|A complete design rethink has resulted in
a machine boasting the highest performance, coupled with the
lowest capital and running costs
|The improved machine geometry of the new
C-Series dramatically reduces electrical energy consumption.
Efficient acceleration of the product in the feed zone
combined with improved internal scroll designs result in
smaller installed horsepower requirements and lower overall
energy consumption ( 20-30% reduction), EFF 1 motors are
fitted as standard.
|Due to a higher internal sedimentation
volume, the capacity is increased by 10-20% above a
similar-sized machine, which ultimately results in lower
investment costs. It is now possible to use a smaller
machine for the required feed rate without reducing
|These technological advances were key to
Euroby winning the project - the Flottweg C series machines
accommodated the increase in throughput without the need for
significant additional space and provided a net reduction in
overall energy requirements together with an increase in
cake dry solids content. Operations staff have also noted a
significant decrease in noise levels.
|Capital costs have been reduced without
compromising material choice. The C range uses
centrifugally cast duplex stainless steel bowls, and
scrolls, featuring flame sprayed tungsten carbide leading
edge coatings which easily withstand all but the most
abrasive sludge, and hard metal wear bushings which can be
easily replaced on site.
|Scroll bearings are sealed for life -
other lubrication is taken care of by a manual or automated
centralised greasing system.
|Power transmission is provided via
Flottwegs superb SimpDriveTM which facilitates speed
differential control based on torque loading.
|The C type Centrifuges and associated MCCs
and support steelwork were supplied and installed at the
Ponsticill site by Eurobys engineers who were also
contracted to remove the redundant equipment.
|All work was carried out without
disruption to the normal operation of the WTP, within budget
and the required timescale.
|Work on each dewatering stream was
completed in turn, with operational dewatering capacity
maintained using one of Eurobys fleet of mobile
