Optimisation of Corrosion Control for Lead in Drinking Water Using Computational Modelling Techniques by Colin Hayes,T. N. Croft,Corine Houtman,Ron van der Oost,H. David Stensel,S. E. Strand,D. Wait,M. Sobsey,D. Wood,J. Funk Pdf

In many respects, lead in drinking water has become a forgotten problem, since the mid 1980s when a range of environmental controls were implemented to reduce exposure to lead. This is largely because the sampling protocols, that underpin regulatory controls, are mostly inadequate and have tended to under-estimate the amount of lead that can be present in drinking water (IWA, 2010). Optimisation of Corrosion Control for Lead in Drinking Water Using Computational Modelling Techniques shows how compliance modelling has been used to very good effect in the optimisation of plumbosolvency control in the United Kingdom, particularly in the optimisation of orthophosphate dosing. Over 100 water supply systems have been modelled, involving 30% of the UK’s water companies. This “proof-of-concept” project has the overall objective of demonstrating that these modelling techniques could also be applicable to the circumstances of Canada and the United States, via three case studies. This report is the first in the Research Report Series published by the IWA Specialist Group on Metals and Related Substances in Drinking Water. Authors: Dr. C. R. Hayes and Dr. T. N.

Internal Corrosion Control of Water Supply Systems by Colin Hayes Pdf

Part of Metals and Related Substances in Drinking Water Set - buy all five books together to save over 30%! This Code of Practice is concerned with metal pick-up by drinking water within the water supply chain, particularly from water mains and from domestic and institutional pipe-work systems. The principal metals of interest are copper, iron, and lead, and to a lesser extent nickel and zinc. The emphasis is on cold drinking water at its point of use by consumers. Metals arising from water sources and hot water systems are not considered. The intention is that this Code of Practice establishes an international standard for the control of internal corrosion of water supply systems. It provides a basis for identifying both problems and sustainable solutions in a manner which is sound scientifically and will help operators to achieve due diligence. It provides a template for improving internal corrosion control in countries, cities or towns where this has been neglected or poorly implemented. Internal Corrosion Control of Water Supply Systems is deliberately brief in its presentation of a wide array of complex information, in order to provide direction to practitioners that can be more easily related to their specific circumstances. The book also provides a series of check-lists and criteria to be used in risk assessment. Editor: Dr Colin R Hayes, University of Swansea, UK, Chair of IWA Specialist Group on Metals and Related Substances in Drinking Water.

Advances in Water Distribution Networks by Giuseppe Pezzinga,Enrico Creaco Pdf

The Special Issue on Advances in Water Distribution Networks (WDNs) explores four important topics of research in the framework of WDNs, namely simulation and optimization modelling, topology and partitioning, water quality, and service effectiveness. With regard to the first topic, the following aspects are addressed: pressure-driven formulations, algorithms for the optimal location of control valves to minimize leakage, the benefits of water discharge prediction for the remote real time control of valves, and transients generated by pumps operating as turbines. In the context of the second topic, a topological taxonomy of WDNs is presented, and partitioning methods for the creation of district metered areas are compared. In relation to the third topic, the vulnerability to trihalomethane is assessed, and a statistical optimization model to minimize heavy metal releases is presented. Finally, the fourth topic focusses on the estimation of non-revenue water, including leakage and unauthorized consumption, and on the assessment of service under intermittent supply conditions.
