WATER AND ITS TREATMENT

INTRODUCTION : Like air water is one of the basic materials which is of prime importance for the preservation of life on this earth. All are aware of the uses of water drinking, cooking, bathing and farming etc. , but few know the importance of water as an engineering material. As an engineering material water is used to produce steam in boilers to generate hydro electric power, furnishing steam for engines, for refrigeration and air conditioning, for construction of concrete structures for manufacturing purposes and as a solvent in chemical process. Hence an engineer should posses knowledge regarding the composition, troubles that arise due to composition of water and prevention of these troubles. OCCURRENCE : Water is widely distributed in nature. It has been estimated that about 75% matter on earth's surface consists of water. Besides visible water on earth, there is a large amount of water under earth to an average SOURCES OF WATER : THE MAIN SOURCES OF NATRAL WATER ARE FOLLOWING...

SOURCES OF WATER – RAIN WATER

RAIN WATER : Rain water is the most important sources of water and the purest from of natral water. It is naurally distilled water as the water from sea, rivers etc. , first evaporates in the great heat of sun to form clouds which afterwards condense and water comes down in the form of rain. As the rain water falls on the surface of the earth and flows as streams or seep through through earth's crust, it takes up dust particles, oxygen, carbon dioxide, nitrogen and other dissolved and suspended solids present in the atmosphere and solid.  ...

Tesla building ‘world’s biggest’ lithium-ion battery in Australia

Australia is famous for the Big Banana, the Big Pineapple and the Big Prawn. Now, another "world's biggest" is coming Down Under, and it's going to be just as much of a tourist attraction if Elon Musk has his way. Tesla is teaming up with French-based renewable energy company Neoen to build the world's biggest lithium-ion battery in South Australia by the end of the year. Tesla CEO Elon Musk jetted into Australia this afternoon to make the announcement, saying the battery will be "three times more powerful than anything else on earth. "The world will look at it as an example... [of] a large-scale battery application for the grid that will really take a large amount of load," he said. "This is definitely the way of the future, and I think other states will be taking a closer look at this and seeing if it's applicable to their needs. And I suspect in most cases it is." The Premier of South Australia, Jay Weatherill, announced the...
