How do Puroserve systems soften water without salt?

The Puroserve system operates using Low Pressure Reverse Osmosis technology. RO is a separation process, that actually separates nearly pure water from hard, or mineral concentrated, tap water. This differs from a sodium softener that utilizes a chemical reaction based on an exchanging of ions. In the case of a salt softener, sodium ions are simply exchanged, using an ion exchange media, for calcium ions. It is also called a Cation exchanger because it exchanges ions that carry a positive charge, or Cations. Where a salt softener leaves a significant amount of sodium ions in the softened water (remember it exchanges sodium for calcium and magnesium), the Puroserve process leaves almost no detectable sodium in the softened water.

Do Puroserve systems waste water?

No. When installed as designed and properly maintained a Puroserve system does not waste any water. In fact, because of it’s advanced design a Puroserve system actually helps to save water. It can make a home more water efficient overall and it will detect water loss and leakage within a home that otherwise may go un-noticed. The key to water efficiency is awareness and, as long as the Puroserve system is properly installed, with a thoughtful eye toward reclamation and re-use, it will save water on MANY levels. Picture the Puroserve system as an advanced technology water resource management system that will actually help your home be more efficient.

Are Puroserve systems okay to use in areas where water softeners are banned?

Yes, the anti-softener ordinances that are being passed in many areas are really salt discharge ordinances, not softening ordinances. Therefore, it is still OK to soften your water, so long as you do not discharge salt to the sewer in order to do it. The Puroserve system does not use any salt. More importantly it does not have a drain or sewer connection. It actually takes in to account all of the tap water that a customer pays for each month, improves the portion that will be used inside and directs the remaining water to be used outside. Nothing is wasted and no salt is discharged to the sewer. In fact, it even reduces natural tap water salt by over 96%, so the water leaving the home and arriving at the waste water plant to be reclaimed, is nearly salt free This makes it easier for waste water authorities to reclaim and reuse more waste water and maintain compliance with their waste water discharge permits.

What other impurities can a Puroserve system reduce?

The Puroserve is capable of significantly reducing nearly all tap water impurities. Based on the molecular size of the specific impurity, the rejection will vary somewhat for each contaminant, however it is fair to say that Reverse Osmosis is the most effective technology available for all common tap water impurities, as well as most emerging contaminants that have become a concern in recent years. Reverse Osmosis has been used for bottling purified water and for making laboratory water for decades.
