This is the normal operating position of the filter. In this stage or position, untreated water flows through the inlet side of the control valve and down through a “captured” dome of air which oxidizes and precipitates iron and or sulfur. As the water flows through the media these precipitated contaminates are filtered by the media. It is at this moment the undesirable minerals are removed from the water.
This is the first cycle in the regeneration cycle. When the system needs to regenerate, it signals the control valve to fill the brine tank with water. Unlike many other systems, the WaterCare system uses conditioned water when making brine solution.
Because the WaterCare systems use a “dry fill” process, salt is less susceptible to “bridging”. Tank sweating is also less likely to result when humid conditions exist. And because conditioned water is used in refill, the tank stays cleaner.
Backwash is a step in the regeneration process where the media in the tank is physically lifted up, spun around and agitated under pressure. It is cleaned of any particles such as precipitated iron or sulfur which has been filtered out during normal use of the system. The backwash water containing the undesirable particles flow harmlessly to drain.
This cycle is the rejuvenating or recharging cycle in the regeneration process. Brine is drawn out of the salt tank and passes through the patented chlorine generator in route to the system’s media. While passing through the generator, it comes in contact with a small amount of electrical current which in turn creates free chlorine from the chlorides in the brine. As the chlorinated brine solution flows through the media, it disinfects the tank and recharges the media. Most of the chlorine is consumed in the disinfection process. Any left over chlorine and brine solution is removed during the system’s rinse cycle.
This is the final step in the regeneration process. It ensures that any remaining salt and residual chlorine has been rinsed from the unit. When the cycle is completed, the unit returns to the service position to provide quality conditioned water.
