Water Softner Plant

Water Technologies-Water Treatment Plant.

Water is considered ‘hard’ when it has excessive levels of Calcium and Magnesium dissolved in it.

HARD WATER CAN LEAD TO THE FOLLOWING WATER PROBLEMS :

scale build-up in pipes resulting in decreased flow rates, scale build-up on heating and cooling systems also leads to increased electricity costs and breakdowns, white film on glasssurfaces and staining on water taps and increased laundry costs due to hard water reacting with soap and laundry detergents.

WATER SOFTENING PLANT :

Our Water Softening Plants are designed to produce treated water to suit various applications. Treated water is of consistent quality with low residual hardness throughout the service cycle. The high synthetic resin is used to exchange Sodium ion with hardness forming Calcium and Magnesium ions. After producing desired output the resin is regenerated with iNaCII Sodium Chloride solution after which unit is again ready to deliver next batch. There are different models available and the difference between these models is in the capacity of the resin used for each model. These units are easy to operate and are maintenance free. These models are available to produce various capacities up to 200 Cu. Meters per hour maximum.

Process for Water Softner :

Water Softner plants treat water to minimise hardness in water that are beyond permissible limits by using high synthetic resins to exchange Sodium Ion with hardness forming Calcium and Magnesium Ions

A water softener reduces the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in hard water.

Hard water is the type of water that has high mineral content (in contrast with soft water). Hard water minerals primarily consist of calcium (Ca2+), and magnesium (Mg2+) metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates. Calcium usually enters the water as either calcium carbonate (CaCO3), in the form of limestone and chalk, or calcium sulfate (CaSO4), in the form of other mineral deposits. The predominant source of magnesium is dolomite (CaMg(CO3)2). Hard water is generally not harmful.

Basically, the resin inside the Vessel is specially designed to remove “hard” particles of lime and calcium, by a simple ion exchange process. The resin beads inside the softener vessel have a different or opposite electrical charge than the dissolved particles of the incoming water. Because of this electrical charge difference, the dissolved particles suspended in your water will cling to the resin beads on contact, thereby ridding the water of these particles, causing the water exiting the unit to be “soft”. The resin has a limit to how much of these hardness particles it can hold, which is why there are many different sizes of softeners and also why regeneration or brining is required.

It is depended on Case to case. Generally Power consumpation require to run only the pumps.

"Softened water still contains all the natural minerals that we need. It is only deprived off its calcium and magnesium contents, and some sodium is added during the softening process. That is why in most cases, softened water is perfectly safe to drink. It is advisable that softened water contains only up to 300mg/L of sodium. In areas with very high hardness the softened water must not be used for the preparation of baby-milk, due to the high sodium containt after the softening process has been carried out."

With the proper maintenance, the average water softener will not need its resins replaced in its lifetime (20 + years). It is impossible to accurately determine the life of resin since so many factors contribute to the degradation of the resin.

The length of time it takes for a water softener to regenerate depends on a number of factors, namely the brand and size of water softener used. Most water softeners require regeneration after a set number of gallons of water passes through the system. However, Culligan’s patented Aqua-Sensor® system monitors the hardness in your water. This monitor can determine exactly when your softener needs to regenerate, allowing you to achieve a savings in salt and water required for the regeneration process. Savings can be estimated at the time the unit is sized.

No, in fact, a water softener can help extend the life of the RO membrane. Calcium and magnesium (limescale) are two of the hardest minerals for the RO membrane to remove, and sodium (added to the water by the softener) is much easier on the membrane as it rejects 98% of all sodium in the water.
