Helping ensure a perfect finish

To ensure a perfect 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 and, when baths are being dumped and re-filled, this can increase by a factor of three.

Veolia 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 and its dedicated control panel, with Siemens graphic display and Ethernet interface to Jaguar Land Rover’s network, was installed in a new plant room. The existing plant continued in operation until the Strata 45+ system had been commissioned, ensuring that there was no interruption to the deionised water supply. 

Veolia’s 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.
