Creating Effective Information Technology Solutions
ISBN: 9781843398776 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Technology offers one of the significant levers that utility managers have available to truly "do more with less." But it often is difficult for managers to know how much to spend on technology, where the expenditures should be, and what the expected return on that investment should be. The objective of this study was to determine successful approaches for implementing utility IT systems considering the range of factors influencing today's utility IT environment. The study cites leading practices that create effective IT solutions (not technology-specific solutions). While specific technology...

Cellular Responses to Arsenic: DNA Damage and Defense Mechanisms
ISBN: 9781843398806 / Angielski / Miękka / 166 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Although ingestion of high levels of arsenic is believed to cause certain cancers, estimates of cancer risk resulting from exposure to low levels of arsenic are the subject of considerable debate. An improved understanding of arsenic toxicity and the dose-response relationship for relatively low levels of arsenic could improve the risk assessment process. The overall objective of this study was to contribute to a better understanding of arsenic health effects. A specific aim was to investigate the cellular response of exposure to arsenic. This includes the analysis of cells treated with...

Managing Distribution Retention Time to Improve Water Quality
ISBN: 9781843399018 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. When water leaves a treatment works and travels through a distribution system, its quality, with respect to many chemical and biological parameters, will degrade. The quality of the delivered water will be largely influenced by: The quality of treated water supplied into the network The condition of distribution assets within the network The retention time within the network. The water industry has focused predominantly on the quality of treated water and the physical condition of distribution assets when improving the quality of water at the customer's tap. However the quality of the water...

Secondary Settling Tanks
ISBN: 9781900222037 / Angielski / Miękka / 232 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Although developments in wastewater treatment over recent decades have focused on the biological reactor, the secondary settling tank (SST) also plays a major role in achieving increasingly stringent effluent quality standards. This report collates many of the significant developments that have taken place in SST theory, design, modelling and operation. Earlier SSTs were designed only by empirical hydraulic criteria such as overflow rate, which do not recognize sludge concentration and settleability. Today, there are available not only much improved design procedures but also hydrodynamic...

Activated Sludge Separation Problems
ISBN: 9781900222846 / Angielski / Miękka / 218 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The Activated Sludge (AS) Process is old technology but is still widely adopted worldwide for its convenience and simplicity: an impressive number (many hundred of thousands) of this kind of system are in operation. Occasionally, problems such as bulking and foaming occur, causing regulation violations and large investment is often required immediately to control them. For this reason, an intense research effort has been made during the last few decades to face these problems, and this report details the work undertaken by the IWA Specialist Group on Activated Sludge Population Dynamics. This...

Water Residuals to Reduce Soil Phosphorus
ISBN: 9781843399520 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Phosphorus in surface runoff from agricultural lands is often implicated in the degradation of surface water quality. Many states are developing soil phosphorus application limits. Utilities must develop and implement new best management practices (BMPs) to control phosphorous. The objective of this project was to investigate the beneficial use of water treatment residuals (WTRs) to control non-point source (NPS) phosphorus pollution and protect surface water quality. Specifically, the researchers planned to examine the unique chemical characteristics of WTRs, namely the large concentration...

ISBN: 9781843399728 / Angielski / Miękka / 176 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Health risks from infrastructure failures are not well understood, despite the potential widespread introduction of chemical, microbial, and physical contaminants, as well as service disruptions. Public health effects due to distribution infrastructure failures are the concern and responsibility of the local water utility, the health department, community medical care providers, and in special circumstances, emergency first response agencies. While the water utility is responsible for safe water, including the operation and maintenance of distribution infrastructure, other agencies including...

Recent Progress in Slow Sand and Alternative Biofiltration Processes
ISBN: 9781843391203 / Angielski / Twarda / 582 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts...
