Water filtration history

Water filtration treatment from



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
Phosphates
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.

20th Century Technology – Phosphates and Ion Exchange
Phosphates
Releases sequestered metals at high temperatures Increase bacterial growth in plumbing systems
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
Bypass needed for espresso and coffee because soft water is not good for coffee extraction
Taste, Expensive Environmental issues
21st Century Technology – TAC and NAC
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
