OPTS FOR HIGH INTEGRITY LIPP SPIRAL
SEAM TANKS FOR LIQUID STORAGE
AND ANAEROBIC DIGESTERS
L
ipp Systems UK has
recently installed six new
spiral seam tanks at a
new bio-energy plant
development in Wakefield, Yorkshire.
These include three large 1,340m2
capacity anaerobic digestion tanks,
an aeration tank, a buffer tank and
finally a water processing tank. Chosen
for unrivalled reliability, ease of
construction and maximum safety – the
new containers aim to produce enough
biogas to power 3000 local homes. As a
by-product the system will also create
soil conditioner for agricultural use.
The Wakefield site has been designed
to process green waste - household
and commercial food and plant
materials, with the capacity to receive
and digest over 65,000 tons per year.
The new tank installations form part
of the South Kirby Anaerobic Digestion
Plant, the green waste section of
the Wakefield project. In its entirety,
the site aims to recycle and reclaim
90 percent of the 230,000 tons of
household waste it will receive per year.
The main contractor for the Wakefield
project specified Lipp Systems tanks
due to their exceptional performance
and safety credentials. With an
impressive reputation for health and
safety, it was important for the main
contractor to preserve these high
standards for work at Wakefield.
Lipp systems tanks were found to be
ideal, as the build process reduces the
amount of time working at heights. All
tanks are constructed from the ground
upwards with apertures and equipment
attached at close to ground level
requiring comparably little work to be
conducted at high elevation. Unlike a
segmented tank, workers will not be on
scaffolding or ropes fitting hundreds of
nuts and bolts.
A primary concern with the storage
of any media is the integrity of the
containment unit itself; escaping
contents or odours present an issue
that can require large outlays to
