Molasses Storage Liner and Floating Covers
The safe and clean storage and
protection of molasses or
other liquids such as potable drinking water in Earthen
Ponds
and Turkey’s Nest Dams can now be economically achieved
using long life UV stabilised high density polyethylene
(HDPE)
geomembrane liner.
These types of molasses storage facilities are more
economical than the typical molasses tank as the capital
cost
is less when comparing similar volumes of molasses storage
capacity.
The storage pond is first made watertight with the HDPE
geomembrane liner laid out on the prepared smooth earth
subgrade and fusion heat welded together to form a complete
seal. It is installed in the base and up the walls of the
pond,
securely held in place in a 500mm deep anchor trench around
the top of the pond crest.
Once the liner is in place the cover is installed over the
liner in
the empty pond.
The cover is placed in the same manner on top of the liner
in
the pond. The cover is also placed into the crest anchor
trench, which is backfilled forming a seal between the liner
and cover material around the perimeter of the pond crest.
Ballast tubes are placed diagonally across the cover to keep
it tight and in place. Floatation tubes are fitted centrally across
and along the underside of the cover to allow a path for any
gas to make its way to perimeter air vents.
The molasses is poured in through the inlet on the crest so
that
it fills the pond between the base layer and the cover layer
of
HDPE geomembrane similar to that of filling a bladder.
An outlet is designed and fitted to suit the desired
molasses removal mechanism whether through pumping or gravity feed draining of
the storage.
Various aspects of the design of these liners and
covers are of a
technical nature and the expertise and years of experience
offered
by Australian Lining Company is required to ensure
the correct
operation and long term life of the molasses storage
structure.
