Advantages and Disadvantages of Distillation BIOTECH. A. scale and sludge formation: the hardness of water fed to the boiler may cause scale and sludge formation. b. corrosion: hardwater may cause caustic embrittlement which is a type of boiler corrosion. c. priming and foaming: hardwater used in boiler causes priming and foaming which results in the formation of wet stream. d. caustic embrittlement, hard water means less lather is produced when using soap this is because it produces soap scum instead of lather. also limescale builds up and this can effect the efficientcy of equipment resulting in higher energy costs..

Softened Water Benefits Study New Reports Related to. Wd-dwgb-3-6 2008 hardness in drinking water definition of hardness hardness in drinking water is defined as those minerals that dissolve in water having a positive electrical charge., hard water is generally considered to be one which requires considerable amount of soap to produce foam or leather. hard water cause scale formation in boilers heaters and hot water pipes. the rain water catches co2 from the atmosphere when the water pass through caco3 rock in the soil, these compounds make the water hard. calcium and magnesium.

In this work, a preliminary investigation of the quality of dodoma municipal water as well as a review of potential methods for removing hardness from this water were undertaken. 19/09/2012в в· carbonate hardness is caused by the metals combined with a form of alkalinity. alkalinity is the capacity of water to neutralize acids and is attributed to compounds such as carbonate, bicarbonate, hydroxide, and sometimes borate, silicate, and phosphate.

Water is the main running substances for wet processing of the textile industry as well as other manufacturing industry. the water which is in the environment that contains lots of impurities which required to purifying before use. the main disadvantage of hard water is it deposits calcium carbonate on pipes, especially hot water pipes. this is called "scale formation". it may cause blockage of pipes and reduce boiler efficiency. also, soap and detergents work less well in hard water. these effects increase as hardness increases.

The main disadvantage of hard water is it deposits calcium carbonate on pipes, especially hot water pipes. this is called "scale formation". it may cause blockage of pipes and reduce boiler efficiency. also, soap and detergents work less well in hard water. these effects increase as hardness increases. hard disks still have some advantages over the alternatives, but the fast development of flash storage and other storage media is likely to make hard drives obsolete in the coming years. hard disk drives are fragile, a problem that flash storage doesn't have.
