| Making water soft is a process that in the past has required the use of salt. The minerals that make water hard are completely “ionized” or dissolved into the water. They are too small to be physically filtered out like you could if you were trying to remove sand or sediment. Therefore, in the past, reducing hardness minerals in water was made possible only by the clever use of a controlled ion exchange reaction.
This controlled chemical reaction requires a lot of sodium ions and a specially developed exchange media or “resin”. The resin, tiny beads that are covered with millions of sodium ions, is able to alter the water chemistry by collecting the hard mineral ions and releasing sodium ions to replace them. This process makes the water “soft” because the hard minerals have been removed, but it also leaves residual sodium in the water. The residual sodium is what causes soft water to feel so slippery. The harder the tap water the more slippery the softened water will feel because the residual sodium content is higher. Once the resin has released all of its sodium ions it must be regenerated. This is a process where the resin is bombarded with salt so that the hard minerals are released and millions more sodium ions may attach to the resin beads.
The salty waste that is created by these systems and discharged down the drain has become a big environmental concern over the years. A typical home water softener unit will discharge up to 500 lbs of salt per year into the sewer. This salt eventually finds its way into the environment via the water reclamation process. The salt can cause problems ranging from poor crop yield to saltier tap water. In some areas salt softeners are no longer allowed for this reason. Many other areas will move to restrict water softeners in the future because of this problem known as urban salinity concentration.
Improvements in technology have allowed Puroserve to develop another way to remove hard minerals that does not require the use of salt or other chemicals. The purification properties of Reverse Osmosis, a permeable membrane filtration process, are well documented. A properly configured Reverse Osmosis system can deliver product water of unparalleled quality. It is not only free of hard minerals (or clinically “soft”) it is also free of salts and up to 98% of all other contaminants.
Reverse Osmosis has traditionally had several limitations that made whole house applications both costly and complicated. The Puroserve HT2000 combines several state of the art features that have allowed us to simplify and speed up the purification process. These advancements have greatly increased the effectiveness of the systems and at the same time have dramatically reduced the costs. Today it is not just possible, but it is also affordable to treat your whole house with an RO system for domestic water purification.
Like any developing technology it took some time for Reverse Osmosis to develop to a point where it was financially and functionally feasible to apply it to whole house domestic water treatment. That time has finally arrived. The Puroserve HT 2000 is much more than just a salt free water softener. It is a whole house water purifier that provides clinically soft water without the salt, the waste or the environmental concerns caused by conventional water softening methods.
