Environmentally Friendly Cylinders go Online

The UK’s longest established cylinder exchange service from Elga Process Water is now available online. Customers can purchase and redeem their SDI vouchers 24/7 and special online only rates will save time and money.

SDI (Service Deionisation) is a flexible, simple and sustainable way to supply a wide range of laboratory applications with high quality purified water (up to 18.2 MΩ) delivered at a flow rate to suit your needs. In addition, to reduce the consumables budget SDI can be connected up front of a water purification equipment to prolong the life of consumables. Users can purchase single pre-paid exchanges, voucher books or take advantage of SDI Inclusive, which provides all the benefits of SDI without the capital costs. Elga Process Water then supplies users with a cylinder containing mixed bed ion exchange resins, which they simply connect to a tap to produce high purity deionised water. When the cylinder is exhausted, all customers need to do is redeem their exchange voucher and a replacement cylinder will be delivered and the exhausted cylinder collected for reprocessing. SDI is supported by Veolia Environmental Services transport fleet, their centrally located depot and route planning technology ensures an efficient delivery system is provided to customers around the UK.

And now there’s more good news: SDI has become even more sustainable. Elga Process Water’s Regeneration Centre at Stoke-on-Trent recycles over 98% of the ion exchange resin used in SDI cylinders and works with a waste recycling facility in Nottingham to convert waste resin into solid recovered fuel (SRF). The resulting material can be burned in licensed cement kilns or power generation plants, with full emission control, where every 2 tonnes of SRF replaces a tonne of fossil fuel. And the bottom ash can be recycled for construction and road building. The reduction in landfill and replacement of precious fossil fuels means a net reduction in environmental impact.
