Background:Welsh Water are the 4th largest company in Wales supplying 1.4 million homes and businesses with clean drinking water. A unique trait among the Water Companies in England and Wales is the fact that we are a not-for-profit organisation. We supply around 830 million litres of water every day through 26,500km of water mains, of which 11,400 are made from cast iron.Research Context:As waters supplied are mostly soft, Welsh Water suffers with internal corrosion of cast iron mains. The corrosion manifests in discoloured water being supplied to our customers. Part of the organisations 2050 Vision is to ensure that all customers are supplied with water free from discolouration; therefore, this issue is a key research area for the company.Project Description:The aim of the project is to investigate how we can prevent corrosion, using a flow through cell. This will enable us to understand real life conditions and the effect of various chemicals as corrosion inhibitors. We would also like to understand the influence of an applied magnetic field and whether this can alter the water chemistry sufficiently to oxidise corrosion products to magnetite.Desired outcomes:- Understand the role of corrosion inhibitors in a flow through cell;- Investigate the effects of applied magnetic fields; and- Understand the cost benefit of applying corrosion inhibitors within the distribution network with mains that are already corroded.

背景：威尔士水是威尔士第四大公司，为140万户主提供了清洁的饮用水。英格兰和威尔士水公司的独特特征是我们是一个非营利组织。我们每天至26,500公里的水管每天提供约8.3亿升水，其中11,400公里是用铸铁来制成的。研究环境：由于所提供的水是柔软的，威尔士的水遭受了铸铁电源的内部腐蚀。这些腐蚀体现在向客户提供的变色水中。 2050年组织的一部分是为了确保所有客户均未提供无变色的水；因此，此问题是公司的关键研究领域。项目描述：该项目的目的是调查如何利用通过细胞流动的流动来防止腐蚀。这将使我们能够理解现实生活条件以及各种化学物质作为腐蚀抑制剂的作用。我们还想了解应用磁场的影响，以及是否可以充分改变水化学，以使磁铁矿氧化腐蚀产物氧化。脱氧的结果： - 了解腐蚀抑制剂在流经细胞流中的作用； - 研究施加的磁场的作用；并了解在分配网络中使用已经腐蚀的电源应用腐蚀抑制剂的成本好处。
