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：威尔士水务公司是威尔士第四大公司，为 140 万家庭和企业提供清洁饮用水。英格兰和威尔士自来水公司的一个独特之处在于我们是一个非营利组织。我们每天通过 26,500 公里的总水管供应约 8.3 亿升水，其中 11,400 根是铸铁总管。 研究背景：由于供应的水大多是软水，威尔士水务公司遭受铸铁总管的内部腐蚀。腐蚀表现为提供给客户的水变色。该组织 2050 愿景的一部分是确保向所有客户提供不变色的水；因此，这个问题是该公司的一个重点研究领域。 项目描述：该项目的目的是研究如何使用流通池来防止腐蚀。这将使我们能够了解现实生活条件以及各种化学品作为腐蚀抑制剂的效果。我们还想了解外加磁场的影响，以及这是否足以改变水的化学性质，从而将腐蚀产物氧化成磁铁矿。期望的结果：- 了解腐蚀抑制剂在流经电池中的作用；- 研究外加磁场的影响；- 研究外加磁场的影响。 - 了解在已腐蚀的配电网络中使用腐蚀抑制剂的成本效益。
