Metal ions such as calcium and magnesium in waters pose various challenges, thus the need to remove them. When in need of water softener Nashville TN presents the ideal place to start the search from. A softener removes magnesium or calcium cations or both from waters. These ions are removed for various reasons. The removal process can be done on small or industrial scale.
The standard unit for computing hardness is grains per gallon or milligrams per liter. A grain is estimated at 64.8mg of calcium. Water is described as being hard if it contains both or either calcium or magnesium cations. Treatment units define waters with one GPG or lower as being soft whereas those with 3.5 to 7 grains per gallon is moderate. Anything above 7 grains per gallon is very hard waters.
Softening is needed for various reasons. Once the hardness is removed the waters lather more easily with soaps. Inconveniences like soap scums are not experienced after softening. Unwanted ions that had initially dissolved precipitate out, thus removing the hardness. The precipitation is in form of scales that collect inside domestic appliances like kettles and heaters. Industrial machinery including pipes gets discolored due to the deposition. Pipes get clogged up and burst whereas slow flow causes mechanical failures.
Reversing the scaling or descaling is achievable through different procedures. Some procedures descale efficiently without tackling the hardness. Pieces of equipment applied in this work reverse the resulting damage due to accumulation of scales. It is essential that buyers know their exact function before closing purchase deals since they do not affect the chemical composition of waters.
There are many techniques of doing away with problems resulting from presence of magnesium and calcium cations. The methods include distillation, addition of chemical softeners, reverse osmosis, and ion exchange resins. Distillation removes the hardness, although the procedure is costly. Rainwater is naturally soft because it undergoes condensation, precipitation, and evaporation through its cycle. Sodium carbonate also called washing soda eliminates the hardness and is good for both large and small scale applications.
Reverse osmosis is based on hydrostatic pressure gradient across a membrane. The membrane used has spaces big enough to allow exclusively water molecules to pass through while leaving behind magnesium and calcium ions. The cations are then washed away using excess water. The membrane used has its limit after which, it has to be replaced for efficiency.
Water-softening devices are based on ion exchange resin in which, the cations responsible for hardness are replaced with either sodium or potassium ions. They are in form of organic polymers that have high attraction for calcium and magnesium ions as compared to sodium and potassium ions. They are designed to absorb sulphate, carbonate, and bi-carbonate ions while releasing hydroxide ions. Once all the sodium ions have been replaced the unit has to be recharged.
In conclusion, the cations, which bring the hardness, have their health advantages. They are needed for health reasons because they hamper poisonous ions like lead and copper from dissolving in waters. Copper and lead cations dissolve completely in soft waters as opposed to hard waters. Once aware of this it is advised, that the metal ions be not removed totally from drinking water.
