Aeration project delivers savings
January 1st 2010 Anglian Water has taken
delivery of Landustrie
aeration equipment that will
deliver energy cost savings of
£37,000/year.
Anglian Water approached
Deritend to replace several
'jet' type aerators with the
aim of improving the
efficiency of the aeration
process in four cascaded tanks.
Deritend undertook a survey
of the site and submitted a
proposal including supply
and installation of Landy-7
aerators from Landustrie.
The savings Deritend
identified were enough to
convince Anglian Water to
proceed with the project,
which included removal of
old submersible units,
installation of new equipment
including bottom baffles and
foundation plates, and testing
for vibration, noise, splashing
and oxygen transfer.
The project took two
weeks to complete, after
which energy savings were
calculated, confirming
original estimates. Power
consumption of the original
set up was 88kW, at an annual
energy cost of £66,000. The
refitted site performed at
33.2kW, costing £29,000 per
annum. More articles from The Deritend Group Ltd: |
