Veolia helps Jaguar Land Rover achieve a perfect finish
A bespoke engineered solution allowed a new deionisation plant to be integrated into an existing system
Water Technologies (Veolia) has supplied a deionised water system to Jaguar
Land Rover’s Halewood factory. The new, bespoke engineered system, which can
deliver up to 90m3/h of deionised water, replaces the 40 year-old
ion exchange plant at Halewood which was reaching the end of its life.
ensure a perfect bodywork finish on all Land Rover models, high purity
deionised water (conductivity <0.5µS/cm) is used at all stages of painting
from phosphating through to final electro-coating. Average water consumption is
almost 30m3/h then, when baths are being dumped and re-filled, this
can increase by a factor of three for short periods.
project management team reviewed the existing plant and concluded that the raw
water, degassed water and treated water tanks, along with the effluent
neutralisation system, could be retained and designed a bespoke ion exchange
plant, based around a standard triplex Rapide Strata 45+ with HiPol polishing,
to produce deionised water of conductivity 0.1µS/cm. The skid-mounted plant,
together with its dedicated control panel, featuring a Siemens graphic display
and Ethernet interface to Jaguar Land Rover’s network, was installed in a new
plant room. This provided business continuity by allowing the existing plant to
continue in operation until the Strata 45+ system had been commissioned, ensuring
that there was no interruption to the deionised water supply and keeping the
paint line running.
well-proven Strata+ uses the latest short-cycle, counterflow regeneration
technology with layered beds. This design improves chemical usage efficiencies
and reduces waste water, achieving long-term cost savings and helping to reduce
Jaguar Land Rover’s water footprint.
