An Introduction for Non-Chemists Analytical Instruments in Water Steam Cycles

Introduction
The outcome of an engineering project such as the design, installation, and commissioning of an analytical system in a power plant will to a large extent depend on specifying the requirements at the outset. Expertise from many different sources are involved. Station chemists, I&C engineers, instrument manufacturers and sampling systems all have to play their part. The instrument manufacturer is often at the end of the line. When they get to quote the instruments, in most cases discussions revolve exclusively around pricing. If there are problems at the commissioning stage or during operation,
however, the instrument supplier is the first to take the blame because they are often the bearer of bad news. Instruments have changed considerably over the last 20 years. Reliability has been increased, and inexpensive microprocessors provide a multitude of new functions. Also, in the meantime the individual design of the steam water cycles has reached a high number of very different design features, while the operational mode has changed dramatically from what was formerly continuous operation to highly flexible operation. These facts should also be reflected in both the engineering and design of sampling systems. New technologies do not necessarily increase costs. They can also be used to provide additional safety and reduce risks and maintenance. This brochure will give an overview of the available technology in power cycle monitoring. Instruments are not considered separately; rather they are embedded in a general discussion of sampling and instrumentation.

Investigation of The Quality of Water Treated by Magnetic Fields
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.

Rapid Assessment of Drinking Water Quality
Introduction
The provision of water was one of the eight components of primary health care identified by the World Health Assembly in Alma Ata in 1978. The Alma Ata Declaration on Primary Health Care expanded the concept of health care to include broader concepts of affordability, accessibility, self-reliance, inter-sectoral collaboration, community participation, sustainability and social justice. The importance of water supply continues to be emphasised as critical to reducing poverty and improving the health and well-being of the World's children and adults. The global community has committed itself to halving the proportion of the world's population who are unable to reach or to afford safe drinking water by 2015. Although great strides have been made in meeting this challenge in terms of provision of services, the safety of many water supplies remains unknown and uncertain. The recent Global Water Supply and Sanitation Assessment 2000 Report provided statistics regarding access to technologies that were either 'improved' or 'unimproved'. This was done on the assumption that some technologies were likely to be better for health, although it was recognised that would not always be the case. However, there was no information provided on water quality within the assessment. The inclusion of information regarding water quality in future assessments of the degree of access to water supplies is desirable. This handbook is designed to help in the implementation of rapid assessments of water quality to improve the knowledge and understanding of the level of safety of water supplies. There is significant value in reporting of independently verifiable water quality data to support national Governments and the international community in measuring progress in achieving the international development targets. Such data provides useful information regarding current conditions, deriving the likely public health burden relate to inadequate water supply and to gain an understanding of the extent of major water quality problems in developing countries. These data would, therefore, provide an indication of future investment priorities and needs on a country, regional and global basis.
