EWS (UK) Ltd are
the sole UK and Ireland agent for a German
vacuum evaporator company. The range of
evaporators available goes as low as 30
l/hr for a standard built unit and in excess
of 500 l/hr for bespoke plant. Materials
of construction vary dependent upon the
liquid being handled and level of concentration.
Vacuum
evaporation results in a concentrate stream
and a condensate stream. Where employed for
reducing volume of effluent resulting from
regeneration of a demineraliser for example,
the condensate is typically of sufficiently
high quality to allow it to be fed directly
back to the demineraliser to make up for regenerant
losses. As the boiling vessel is operated
under vacuum this also negates the need for
a separate feed pump where the evaporator
is installed close to the feed liquor storage
tank.
With
increased off-site disposal costs and environmental
legislation driving companies to consider
resource recovery, evaporation is being increasingly
considered by companies looking to reduce
costs and achieve environmental targets.
