PCM Moineau
Filter Press Feeding
PCM Moineau filter press feeding (FPF) provides a cost-effective and
reliable solution for plate feeder press used in environmental
dewatering applications or product concentration and solution filtration
in industrial processes.
Used in conjunction with an appropriate automation system, PCM Moineau
pumps offer a cost-effective means of feeding filter presses while
guaranteeing optimum operation throughout the different phases of the
filtration cycle. With FPF it is possible to control pump capacity
during the feeding and high pressure phases as the user wishes, with the
latter able to implement up to 5 operating graphs. FPF can be used to
manage the injection of polymer in proportion to the theoretical or real
sludge flow rate, and includes macerators to protect the pumps. The
filter press feed consists of one or two PCM Moineau pumps, depending on
the size of the installation, linked to a control system that is
compatible with all supervision links.
Undeniable Benefits
When associated with a Moineau pump, FPF automation offers many
advantages:
User-friendliness
The monochrome or colour screen graphic user interface makes it easy to
use and set up FPF. This system (available in 4 languages) can be used
to trace and create graphs for implementing pressing in function of duty
conditions. The program is designed to operate in expert mode with
reference graphs serving as the basis of system control.
Flexibility of operation
Dynamic display of the operating graphs facilitate improved monitoring
of the filtration cycles.
All events (operating and fault data) are archived and can be consulted
at any time, and a comprehensive online help ensures their easy
interpretation. Likewise, maintenance data is stored, offering flexible
operating opportunities.
Scalable system
With FPF, dewatering installation modifications can be integrated easily
and rapidly, such as the addition of a pump protection macerator or a
control flow meter.
A variety of applications
FPF can be integrated in equipment set-ups when installations are
deployed or when existing equipment is replaced on-site. It is
particularly suitable for sewage sludge treatment and for environmental
applications for the manufacturing industries, as well for manufacturing
processes such as those carried out in the food processing and
paramedical industries (e.g., beer yeast filtration) or the materials
industries (e.g., ceramics, quarrying).
A concrete example:
Europhil Sife, a surface treatment company (zinc, nickel, copper
coatings) that works notably as a sub-contractor for the automobile
industry, has been using PCM Moineau FPF filter press feeding since
January 2003.
Their system consists of a PCM 20l16 pump, with a fill capacity of 8 m3
/h and an end-of-cycle pressure of 15 bar, for sludge recovery of liquid
metal hydroxide sludge at the output of the physical-chemical treatment
station. The installation ensures that their site specification
requirements are respected, including maintaining and improving sludge
quality, obtaining a dry solid content of greater than 30%, reducing the
cycle duration and keeping the noise level to a minimum.
Over the past year, the company was able to observe the efficiency of
the FPF system, which has brought with it many benefits and allowed them
to improve both productivity and the working conditions in their plant.
Europfil Sife also reports that they have experienced no technical
problems with this installation and that no maintenance work has been
required since it has been up and running. <<
