Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water.
The resulting soft water is more compatible with soap and extends the
lifetime of plumbing. Water softening is usually achieved using ion-exchange resins. The presence of certain metal ions in water causes a variety of problems. These ions interfere with the action of soaps. They also lead to build up of limescale, which can foul plumbing, and galvanic corrosion. In industrial scale water softening plants, the effluent flow from
Hard Water Treatment
Water described as “hard” is high in dissolved minerals,
specifically calcium and magnesium. Hard water is not a health risk, but a
nuisance because of mineral buildup on fixtures and poor soap and/or detergent
performance. Water is a good solvent and picks up impurities easily. Pure water
— tasteless, colorless, and odorless is often called the universal solvent.
When water is combined with carbon dioxide to form very weak carbonic acid, an
even better solvent results. Water described as “hard” is high in dissolved minerals,
specifically calcium and magnesium. Hard water is not a health risk, but a
nuisance because of mineral buildup on fixtures and poor soap and/or detergent
performance. Water is a good solvent and picks up
All About Deep Sea
Deep sea is part of the deepest layer of oceans. Deep sea has alot of unthinkable stories,secrecy and legends that make mankind more currious about the live that is surviving bottom of the see. We never think something special about deep sea, but for mankind and researcher, deep see has something special. There are so many kind of fish, shrimp, crab, and other kinds of fishes that are different from other fishes. Deep sea creatures are nothing but fishes and other animals that survive down in the deepest part of the marine. The coral reef is a platform for these far-fetched living things. Fishes are presented in different shapes and abilities. Some of them don't look like fishes but resemble to eels (a fish that has a long thin body similar to a snake). You can
Groundwater
Traditionally, management of water resources has focused on surface
water or ground water as if they were separate entities. As development
of land and water resources increases, it is apparent that development
of either of these resources affects the quantity and quality of the
other. Nearly all surface-water features (streams, lakes, reservoirs,
wetlands, and estuaries) interact with ground water. These interactions
take many forms. In many situations, surface-water bodies gain water and
solutes from ground-water systems and in others the surface-water body
is a source of ground-water recharge and causes changes in ground-water
quality. As a result, withdrawal of water from streams can deplete
ground water or conversely, pumpage of ground water can deplete water in
streams, lakes, or
