Water filtration history

Once upon a time . . . . . .

Some companies and products once upon a time were so large and well-established, it seems like they could never go out of business. But innovation can quickly leave a business behind if it can’t adjust to new ways of operating, or to changing customer demand for new products and services.

Water filtration history:

Water softener

1903: Ion exchange invented


1887: First recognized in water treatment.
1930’s: “Threshold Treatment”- use of few ppm sodium hexa-metaphosphate powder to potable water for control of calcium carbonate scale.
1970’s: Zinc phosphates introduced for the treatment of low hardness aggressive water supplies (Murray AWWA 1969)

Reverse Osmosis

1748: First introduced by Jean-Antoine Nollet
1940s: Researchers from top American universities began to reconsider the topic. Renewed interest was based on a desire to find a way to filter or desalinate sea water, which was a goal set by the Kennedy administration to help develop water shortage solutions for the country.
1959: Two researchers at UCLA, Sidney Loeb and Srinivasa Sourirajan succeeded in producing a functional synthetic RO membrane from cellulose acetate polymer.

You can’t take on 21st century tasks with 20th century tools and hope to get the job done

20th Century Technology – Phosphates and Ion Exchange


Not effective for high levels of metal concentration

Releases sequestered metals at high temperatures Increase bacterial growth in plumbing systems

Less effective with time; reverts from poly to orthophosphates
Makes water taste metallic

Calcium Phosphate Scale 


Polyphosphates not Effective over 10 grains


Capacity drops as grains of hardness increase
Water consistency(Polyphosphates should be used with dosing pumps. When used in point of use filters they are alway being released into water inside the cartridge. So when equipment is sitting the ppm of the phosphate becomes higher and higher inside the cartridge.

Ion Exchange

Exchanging Calcium and Magnesium ions for Sodium and Hydrogen Ions
Lowers pH in water

Bypass needed for espresso and coffee because soft water is not good for coffee extraction 

Capacity and size
Sodium and Hydrogen ions linked to high blood pressure and acidic body cells that can lead to cancer

Taste, Expensive Environmental issues

21st Century Technology – TAC and NAC

NAC (Nucleation Assisted Crystallization) from Watch Water developed in Europe utilizing a ceramic bead as a catalyst that turns hardness molecules into harmless crystals. These suspended microscopic particulates are then flushed through the plumbing either down the drain or are consumed. This hardness transformation of calcium and magnesium no longer adhere to the plumbing, boilers, fixtures or equipment, thus extending the life and usage of these components.

No salt (ion exchange) or other additives such as Phosphates to the water (a standard industry used chemical). Attacks existing scale caused by existing hard water deposits, making it the preferred choice plus its guaranteed with proven results. Our media allows equipment to operate practically maintenance free with minimal down time.

Due the slower timing process, over time the TAC media will start to break down, which is typically seen in the 1st year after installation. TAC media is also not recommended for temperatures higher than 140 degrees. CO2 blends into water. TAC lowers pH and in most cases water becomes acidic. Removes existing scale but has no corrosion protection and can make o-rings and gaskets leak.

Due to the faster process of the molecules, NAC life expectancy is typically (3) years and can sustain temperatures of up to 189 degrees
