Water Quality Indices

  • Type: Book
  • -
  • Published: 2012-03-10
  • -
  • Publisher: Elsevier

This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water qual...

Renewable Energy Sources

Today, the tide has turned so strongly in favour of renewables that for the first time since the dawn of the fossil fuel era over two hundred years ago renewable energy technologies have started attracting more investment globally than that in the fossil fuel-based technologies. This text provides a comprehensive and wide ranging introduction to various renewable energy technologies and their applications, such as solar, wind, biomass, biogas, wave, geothermal, tidal and small hydel. It provides a thorough understanding of the basic energy conversion processes taking place in various renewable energy-based equipment like heat engines, photovoltaics, wind turbines, windmills, wave machines, and so on. The text also deals with the impact of renewable energy sources on global warming and pollution. The book is intended for courses in Environmental Sciences, Environmental/Electrical/Mechanical Engineering and Energy Studies at the undergraduate and postgraduate levels. It will also serve as a useful reference for scientists, technocrats and environmentalists.

Biogas Energy

In recent years, the importance of biogas energy has risen manifold and has become universal. This is due to the realization that biogas capture and utilization has great potential in controlling global warming. By capturing biogas wherever it is formed, we not only tap a source of clean energy, but we also prevent the escape of methane to the atmosphere. Given that methane has 25 times greater global warming potential than CO2, methane capture through biogas energy in this manner can contribute substantially towards global warming control.

Wastewater Treatment Systems based on Vascular Plants

  • Publisher: Elsevier

The last book covering a part of this subject has come four years ago (Vymazal, J., and Kropfelova, L., 2008. Wastewater Treatment in Constructed Wetlands; Springer, New Yark) and the one prior to that six years ago (Crites R. W., Middlebrooks, E. O., and Reed, S. C., 2006, Natural Wastewater Treatment Systems; CRC Press, Boca Raton). Both are excellent treatises but neither covers systems based on ‘nutrient film technique’ even as it is in this segment that most spectacular advances are currently occurring. Moreover, the state-of-the-art in all systems has advanced significantly since these books came out. The proposed book would, therefore, be much more comprehensive as well as up-to-date. Covers a topic of very great contemporary relevance Will have a world-wide catchment First of its kind since several years It has a huge market waiting Written by authors with established track record Adds to the book’s market appeal High on substance Its appeal will endure Written in a lucid, clear, and compact style Will please and satisfy the reader Supported by tables, graphs, half-tones and references Will enhance the book’s visual appeal and user-friendliness
