Digging deeper
The plant at
Davyhulme is the
largest of its type
in the world and
cost £105m
• In Action
Yorkshire Water
● Yorkshire Water aims to make its Esholt
works completely self-sufficient when it
comes to energy with the aid of AD. It has al-
ready installed two high efficiency combined
heat and power generators at a cost of £1m
each. These create around one third of the
energy required to power the plant each day.
A £30m project will see further improvements
to the way sludge is treated as the AD proc-
ess is converted to advanced digestion with
thermal hydrolysis. A new facility will allow for
increased bio gas production for renewable
energy generation.
By adding a fourth digester the site will
become much more environmentally friendly
and move it towards its goal of energy self-
sufficiency. Carbon emissions will also be
cut as well as the miles needed to transport
material.

Non - compliance
What could this mean to you?
Pollution, closure, heavy fines, negative publicity, loss of profits?
Industries treat acidic effluent in different ways, but many are now turning to
Neutralac SLS45, the UK's fastest growing, high strength liquid lime.
Utilities, Metals, Chemical and Food manufacturers are all under compliance
pressure to meet increasingly stringent wastewater treatment legislation,
and why many are harnessing the benefits of Neutralac SLS45.

while generating renewable energy to power
WwTWs and return to the grid. Investment in
AD processes and plants is set to continue and
water companies really are becoming centres of
excellence for a technology that is likely to play
an ever more important part in the UK's energy
generation mix.
