Template Assisted Crystallization is a new water treatment method to prevent scale formation in pipes and appliances.  It does not utilize salt.  Some people hate salt.  Okay, I understand this but remember: we need salt to survive. 

 TAC has been studied at the college of sustainable studies of Arizona State University by Dr. Fox.  As I understand Dr. Fox does not like soft water.  He searched the most effective alternative to soft water. 

There have been many alternative methods of water treatment in the past that relied on magnets and a variety of electrical devices to send waves and pulses through pipes in an attempt to rearrange the molecular structure of the water’s hardness (calcium and magnesium) ions.

TAC works differently.  TAC utilizes a standard mineral tank and the water passes through the granular medium.

TAC is not like a softener, there is no need for salt or water waste.  No drain is necessary.  There is no electricity required.  TAC water treatment units are much easier to set up.

There are a variety of brand names for TAC.  We have chosen to utilize Filtersorb SP3 and ScaleStop.  These are the most reliable. 

 TAC media does not remove calcium and magnesium ions from the water; it changes these hardness minerals from their ionic form to a harmless crystalline form.  In this very stable form, calcium and magnesium do not attach to pipes, appliances, and fixture surfaces. The crystals are so small, in fact, that they are readily rinsed away by the normal flow of water. This technology is often referred to as “template assisted crystallization,” or simply TAC.

If you want to get a little more technical, Chubb Michaud explains TAC as follows: “TAC employs a special surface-treated resin bead to act as a catalytic nucleation site for the conversion and growth of hardness crystals, which are subsequently released and remain in solution without forming scale.” Another writes, similarly, “Atomic sized nucleation sites on the surface of small ceramic-polymer beads convert dissolved hardness into microscopic crystals. Once the crystals grow to a certain size they are released from the bead. The crystals in solution keep the hardness out of the water so that it can’t form scale or interfere with soap.” And another writes, “Unique ‘Template Assisted Crystallization’ (TAC) technology induces the formation of microscopic calcium crystals which effectively isolate hardness from the water chemistry.”

TAC application has gained wide acceptance in a short time.

The Filtersorb SP3 is designed, tested, and built by Boyett’s family water treatment using anti-scale medium: we also provide a whole house carbon filter to remove all the chlorine.

The delivery system used with Filtersorb SP3 is much simpler than that of conventional water softeners. Only a small amount of Filtersorb SP3 is needed; it is used in a full-sized mineral tank—the same tank used for softeners and large filters—to assure adequate contact time.

Unlike softeners, Filtersorb SP3 units have no connection to drain and no electrical connection is needed. No regeneration of the medium is required.

Here are some things to consider about Filtersorb SP3:

  • Filtersorb SP3 needs less contact time than softener resin, so smaller treatment tanks can be used per service flow.
  • No salt, chemicals or other regenerants are required.
  • No backwashing, so no connection to drain or water use.
  • Commercial grade Filtersorb SP3 units are made by simply adding more of the treatment medium to the contact tank.
  • No brine discharge. (Filtersorb SP3 units can be used in areas where conventional water softeners are banned or regulated.)
  • Granular Filtersorb SP3 has a lifespan of 5 years.
  • An important difference between Filtersorb SP3 and softeners is that Filtersorb SP3 actually removes existing scale from pipes and appliances. Softeners prevent new scaling but do not remove existing scale buildup.
  • Unlike softeners, Filtersorb SP3 units do not add sodium to the water.
  • Maximum hardness treated by the standard residential system is 25 grains. Commercial units are available for harder water or extended service runs, or residential systems can be oversized to compensate for added hardness.
  • Filtersorb SP3 units require no cleaning or chemical conditioning agents.

Does Filtersorb SP3 media need to be changed every 5 years?

conclusion of Dr. Fox study

• The most promising technology is the template assisted crystallization with scale reductions of over 90%.


What makes us the best company to provide this service to you?

For 52 years we have become experts in evacuating media from tanks efficiently.  This is necessary for TAC.  Every five years this media must be exchanged.  Our company has a specially designed computer software to keep track of your equipment and notify you when it is time for your service.  We specialize in exchanging water treatment equipment.

We have established our prices so you save over $2,890 every five years.

Here are some pictures of our infrastructure that makes us the best to provide you this service:

This area is an important place for our recycling program.  We call this the media evacuation area.  Because we have taken time to establish this area and clean our equipment regularly to get rid of the old Filtersorb SP3 media and carbon we save thousands of pounds of trash from the land fill (we reutilize the media tanks and valves).  By recycling many of our tanks and valves we save you money.   We exchange your rental water treatment equipment on a scheduled time period to make sure you have A+ water – 100% of the time.

The man shown in this picture is Dave Green.  We have worked with this fine character since the year 2000.  He is responsible for all of our concrete modifications and upgrades.  Dave Green helps us work efficiently and ergonomically sustainably.   Dave Green is a very loyal and trustworthy concrete craftsman.

I took a picture of this area at night

Because of all our work and effort, we feel that our company is the most qualified to provide salt-free water treatment service to Scottsdale, AZ and salt-free water treatment service to Cave Creek, AZ.  We also provide rental water softeners in Coolidge AZ and we provide rental water softeners in Queen Creek Arizona.  Along with our Filtersorb SP3 efforts to provide salt-free water:  we specialize in providing rental reverse osmosis in Buckeye, AZ and we provided rental reverse osmosis in Florence, AZ.
