Severn Trent Water必须在英国的17个地下水现场安装除砷工艺，以在2003年之前达到10 ug/L的新监管标准。1995年开始了一项广泛的开发计划，包括实验室和中试规模的试验。颗粒铁介质吸附被认为是处理Severn Trent地下水的最佳技术。英国第一座全尺寸砷吸附厂于1999年建成，允许进一步优化工艺。研究了颗粒状铁介质的其他应用，包括通过过滤和砷吸附同时去除铁，以及点式过滤的可行性- 在设备使用方面，去除有毒重金属和处理浓缩废物的能力。包括9个参考文献、图表。

Severn Trent Water must install arsenic removal processesat 17 groundwater sites in the United Kingdom in order to comply with the new regulatory standard of 10 ug/L by 2003. An extensive development program commenced in 1995, including laboratory and pilot-scale trials. Adsorption with granular ferric media was found to be the best technology for treating groundwater in Severn Trent. The first full-scale arsenic adsorption plant in the United Kingdom was constructed in 1999, allowing further process optimization. Other applications for granular ferric media have been investigated, including simultaneous removal of iron by filtration with arsenic adsorption, the feasibility of Point-of-Use devices, the ability to remove toxic heavy metals and treat concentrated waste material.
