Floating is that
operation through which solid substances,
suspended or in emulsion, are separated from the
liquid, either using their low specific weight
either causing their floating through the
injection of gas flow. In both cases we obtain
the advantages of Archimede’s principle for the
bodies immersed in a fluid.

This
process can be applied to the depuration
of discharged water which contains
suspended solids, oils, greases, fibers
and other substances with a specific
weight lower or near to the one of
water; substances that it is difficult
or impossible to sediment.
The light weight sludge that is forming
on the water surface is separated and
removed by special conveyors
|
The floater is of
hydrodynamic type and is divided in more
sections : in the first section, due to
particular conditions of quiet, the discharged
fluid can separate itself from the coarser
floating substances through a simple
stratification; in the second section the
discharged fluid is deeply mixed with air
saturated water, so that the flocks and the
particles are enclosed in a flow of
micro-bubbles of air that eases the separation
by floating; in the third section the discharged
fluid passes through a reticular sandwich of
plastic material that, because of the slowing
down of the flow and for the effect of
“coalescence” allow also the smallest and
lighter floating substances to separate from the
discharged fluid; in the forth and last section
we have again a “quiet” section with exit by
siphon for an increased accuracy. The sludge is
collected in a special tank or sent directly to
the sludge drying system (filtering bags or
press-filter). The plant can be completed with
neutralization sections, coagulation sections,
denaturing sections, flocculation sections
according to the needs of the customer.
The plants are
supplied either according to our standard design
or according to customer specific needs.
The models up to 25 m3/hour, can be made with
modular elements or with pre-assembled and
pre-tested elements. The plant automation can be
made either with electro-mechanic control
cabinets or with programmable logic controllers
(PLC).
For our customer we have a test plant that can
be installed in their factory to test the
results with their discharge fluids
Our plants are designed and produced
according to the current safety norms and the
latest technologies. Our Technical Office uses
the most rigorous standards in the selection of
the components and the devices for our plants,
in order to optimize the operation and increase
the reliability and durability of our plants. |
