The ixstream™ Regeneration Process

The ixstream™ water conditioner is equipped with a brine tank to provide a source of dissolved Potassium Chloride for regenerating the resin and an automatic control valve to direct the flow of water during service and regeneration cycles. ixstream™ water conditioners are adjustable to meet the efficiency standards of recent environmental legislation and an increasing desire to conserve natural resources.

At the beginning of the service cycle, Potassium and Chloride ions occupy the resin's exchange sites. As water passes through the charged resin, a stronger affinity for hardness and other unwanted minerals causes the resins to take on those unwanted minerals and give up its Potassium and Chloride ions. Certain variables such as: TDS, temperature, flow-rate, contaminant levels and other factors can affect the performance of the treatment process. When the capacity of the resin has been exhausted, the ixstream's™ automatic control valve uses the Potassium salt brine to rinse the TechSoft and TechBlend media, driving off the unwanted minerals and recharging them for the next service cycle. This multi-step regeneration process typically takes about 80 minutes to complete.

The automatic control valve carries out each regeneration cycle. The regeneration cycle starts with an upflow backwash (lasting 5-10 minutes) that lifts and re-sorts the resin bed while flushing out suspended particles and sediment. During the brining cycle that follows, a solution of Potassium Chloride (or Sodium Chloride) is passed through the resin media. A jet stream eductor within the control valve draws concentrated brine from the storage tank while diluting it to the proper concentration. The regulated brine draw lasts from 10 to 25 minutes depending on the regeneration dosage of salt being used. The brining releases hardness and other unwanted minerals from the resin beads. Brining is followed by a slow rinse (lasting 30-45 minutes) that displaces spent and excess brine from the resin bed. The rinse carries to the drain the hardness and unwanted minerals that were released from the resin bed. A final fast rinse, lasting about 5-minutes, flushes any remaining brine from the resin media and tightly packs the media bed to prevent raw water from passing through the resin bed untreated during service. The automatic control valve then refills the proper amount of fresh water to the brine storage tank to dissolve brine for the next regeneration cycle.

Fundamentals of the ixstream™ Ion Exchange Treatment Process

Water that contains dissolved calcium, magnesium iron and manganese is commonly referred to as "hard" because these metals can combine with other compounds to leave hard scales or stains on the surfaces they touch as well as interfering with the effectiveness of soap and other cleaning products. Water may also contain other dissolved unwanted minerals such as lead, nitrates, arsenic, aesthetic chlorine, aluminum, organics that produce off tastes and odors, and other impurities. The proper selection of a Utah Water Systems ixstream™ ion exchange water conditioner can greatly reduce or eliminate the problems caused by the presence of hardness and other unwanted minerals from water supplies. The ixstream™ is not intended to serve as a filter for removal of particulate matter. Utah Water Systems Industries offers other products that are specifically designed for this purpose.

What makes the ixstream's™ resin blend unique

The Utah Water Systems ixstream™ is a family of ion exchange water conditioners designed to treat water containing one or more unwanted minerals. A typical unit is equipped with one or two pressure tanks partially filled with one or several ion exchange resins. Our TechSoft™ and TechBlend™ media consist of highly porous, that are loaded with ion exchange sites. There are millions of these ion exchange sites within a ixstream™ conditioner tank. These resins are preferentially attracted to hardness and other dissolved unwanted minerals. Each cubic foot of TechSoft resins can remove about 32,000 grains (exchange capacity) of hardness when dosed with 15 pounds of Potassium chloride. At a lower (economy) dosage of 6 pounds per cubic foot, the TechSoft resin yields about 20,000 grains of exchange capacity. This lower dosage is more cost-efficient, but it requires more frequent regeneration. TechBlend resins vary in capacity and selectivity and are engineered to meet specific application and unwanted mineral removal requirements.
