Pumps In Water Treatment
INTRODUCTION : 1.1 Why water treatment?
Pure water [H2O] is a colourless, odourless and tasteless liquid. It plays a huge part in everyday life: 70% of the earth’s surface is covered by water in the form of oceans, and the rest of the planet has large quantities of water in the form of lakes, rivers and watercourses, ice and snow, and humidity, as well as the principal element of animal life (>50%) and plants (approx. 80%). When we talk about water in general, we usually mean water for some specific purpose, e.g. drinking water or process water for industry. This is where the term water treatment comes into the picture, as the available water resources or that provided by nature is not always of a suitable quality for immediate use for the specific purpose. Drinking water must be pure, and should preferably taste good too, and it must not contain substances that could cause problemswith daily use. Process water, which is water that forms a direct and important part of a process or product in industry, must have a chemical composition and temperature that is precisely suited to the specific requirements.

Centrifugal Pump Application and Optimization
Summary
Centrifugal pumps perform many important functions to control the built environment. The physics and basic mechanics of pumps have not changed substantially in the last century. However, the state of the art in the application of pumps has improved dramatically in recent years. Even so, pumps are still often not well applied, and become common targets in retrocommissioning projects where field assessment and testing can reveal significant energy savings potential from optimizing pump performance. Typically, retrocommissioning finds that pump flow rates do not match their design intent and that reducing flow rates to match load requirements or eliminating unnecessary pressure drops can save energy. As the example below illustrates, decisions made during the design phase have implications throughout the operating life of the building. Although fully optimizing any design will require some effort after installation, the prevalence and magnitude of the savings that are commonly found in retrocommissioning and ongoing commissioning begs the larger question: How much greater would the savings be if pumps were selected and applied optimally during the design phase?
