WATER SOFTENER PLANT | SYSTEM | UNIT MANUFACTURERS CHENNAI
What is Hard Water? As water returns to earth in the form of precipitation it filters into the ground dissolving everything from rocks and minerals to pesticides. Hard water has high calcium and magnesium content caused primarily from contact with limestone. Hard water minerals cause significant problems when combined with soap or heat by forming scale and soap curd. Water softeners protect you from both the expense and nuisance caused by hard water.
Scale builds up in your plumbing and water using appliances causing premature failure, decreased performance and higher operating costs. Scale also causes spots of glass shower doors, dishes, cutlery and glassware.
Soap scum adheres to skin and hair – clogging pores – making skin dry and itchy and hair dull. Scum also sticks to sinks and tubs making cleaning a headache.
Soft Water Benefits You Can’t Ignore
How many products pay for themselves in savings plus provide numerous benefits to improve your life?
Soft water offers real benefits:
– Silky smooth hair
– Soft supple skin
– Spot-free glassware, cutlery and dishes
– Keep laundry crisp white and vibrant
– Protect fabrics from curd build-up
– No scale or scum or build-up on tubs, sinks and fixtures
How a Water Softener Works
Water Softeners Have Four Main Components:
1) Control Valve- directs the flow of the water within the unit and determines when the unit needs to regenerate
2) Ion Exchange Resin- small polymer beads that attract the hardness minerals in exchange for sodium ions
3) Pressure Tank - contains the ion exchange resin
4) Salt Cabinet or Brine Tank- contains the salt to make the brine solution that is used to regenerate the ion resin bed
The Softening Process
A water softener exchanges calcium and magnesium ions (hardness minerals) for sodium ions. The raw water runs through a bed of small resin beads contained in the pressure tank. Sites on the beads are covered with sodium ions. As the water runs through the bed, the calcium and magnesium ions are exchanged with sodium ions. Eventually the resin beads will contain only hardness minerals.
The control valve monitors the water usage and is programmed to regenerate the night before the bed becomes completely exhausted ensuring you always have soft water. When the control valve initiates regeneration it is first back washed by reversing the water flow through the unit to expand the bed and rinse debris and impurities from the system. Then a brine or salt solution that has been made in the cabinet is drawn through the resin bed and the ion beads release the hardness minerals in exchange for the sodium. A final rinse washes away the hardness minerals sending them to the drain. Now the softener bed is fully recharged and ready to soften again.
