During normal operations, raw water passes through the ion exchange resin media in the tall tank. As the softener removes hardness minerals from the water supply, sodium or potassium will be given back proportionally. To determine the increase for your situation, divide your total hardness by 10 and then multiple that result by the appropriate number in the right hand column. The regeneration process begins by a rapid backwashing of the resin to remove fine particulate material which originates in the well or piping. Advantages Of Water Softening Softener resin can be regenerated and re-used.
Ion exchange can consistently remove hardness from water to extremely low levels.
Softening removes dissolved iron and manganese. Other water quality factors such as pH, alkalinity and dissolved oxygen are not critical to removing iron and manganese. Conventional softening also removes dissolved radium. The process is equally as efficient however the cost of potassium chloride is higher than sodium chloride Softening will not operate satisfactorily if iron bacteria, clay particles, rusty colored water etc. exists, even occasionally. Water softeners require a location to disposal of waste brine.
