Problem Solving

About this book : This book is a compilation work of various techniques adopted at different parts of the world for removal of a range of chemical parameters which are present beyond the permissible limit in drinking water. The different technologies those are described in this book are mainly limited to household level and for community level. The stepwise pictorial presentation for treatment of contaminated water to remove different chemical parameters and biological treatment will possibly be appreciated by the readers of this book. The authors of this book have tried their best, put their utmost thought and taken maximum care while compiling the available information so that this piece of work will be accepted by every individual. This book in general comprises three sections and eight chapters are within these sections. Section-I comprises only one chapter which describes different water quality problems in India with specific interest to Odisha and for whom this book is designed. Similarly, the section-II encompasses four chapters. Water quality standards, water quality occurrence in different parts of the state and its presentation in shape of a map are reflected in these chapters. Section –III, which is the most important section of this book, illustrates identification of problems and their mitigation measures at household level as well as at community level. Material quantification and maintenance procedures are also depicted in this section.

Abstract Passing water through a magnetic field has been claimed to improve chemical, physical and bacteriological quality of water in many different applications. Although the treatment process has been used for decades, it still remains in the realms of pseudoscience. If the claims of treating water with magnets are true, the process offers improvements on many of our applications of water in today’s world. A large number of peer reviewed journal articles have reported contradictory claims about the treatment.. Some of the most beneficial claimed water applications from magnetically treated water include improvement in scale reduction in pipes and enhanced crop yields with reduced water usage. Today we are still unsure whether the technology works and those who do believe it works are still trying to understand the mechanisms of how it works. Many research papers are starting to develop similar theories behind the mechanism of the treatment. From previous studies, it has been determined that the most successful MTD’s are those with alternating poles. The majority of the experiments performed during this research were determined to have insufficient controls to produce conclusive results. The conclusions from this research were focused on designing improved experiments to provide more conclusive results. A theory was developed to explain the MTD’s mechanisms of scale reduction. While the experimental results were not conclusive, the results attained backed the theory. Magnetically treated water does not do all that it is claimed it does. However, some of the positive results obtained during this research suggest that the improved experiments developed from this research may provide conclusive results on this controversial topic.
