Two massive
28 tonne sludge dryers (photo), each measuring the length of six cars have
successfully completed a two day journey from Austria to Hyder's
new waste water treatment works in Cardiff.
The whole exercise
was a masterpiece of skill and engineering, and is one of the key
stages in the construction of the £180 million flagship works due
to be completed in 2002.
The state of
the art waste water treatment works will serve a population of 880,000
including most of Cardiff and the Valleys.
It will mean
that raw sewage currently being discharged from four outfalls along
the coast is diverted to the new works and fully treated before
being discharged as clean water into the River Severn from a new
4 km long sea outfall.
Jeff Martin,
Hyder's Project Director said: " The arrival and installation of
the sludge dryers is another milestone in the construction of this
extremely important project."
The 28 tonne
sludge drying drums and 7 tonne furnaces dry the sewage sludge,
which is a by-product of the treatment process, reaching temperatures
of up to 500 degrees centigrade, and evaporating seven tonnes of
water an hour. Small pellets are produced which may be used as an
agricultural fertiliser or as fuel to generate power.
Austrian based
machine and plant manufacturers, Andritz AG, built the dryers and
have the contract for turnkey installation of the completed drying
plant through their UK affiliate Andritz Ltd. Low loaders manoeuvred
the drums into the specially built drying house with five centimetres
to spare either side of the entrance!
Ray Spary, Site
Manager for Andritz AG said: "This treatment works is leading the
way for the future. It will certainly benefit everybody in the locality
and we can all look forward to a cleaner environment."
