NSF Certificate Strong Acid Cation Resin for Water Filter

 

 

Lanlang NSF Certificate Strong Acid Cation Resin for Water Filter is a product that can help you get clean and fresh water. It is made with high-quality materials and is certified by NSF, one of the leading organizations in the world for water treatment and filtration.

 

For Hardness Softening your water by releasing Hydrogen (H+) ions or other positively charged ions in exchange for impurity cations present in the water. The calcium and magnesium ions are exchanged for an equivalent number of sodium ions. The resin, once exhausted, must be re-charged. This entails passing a solution containing a high concentration of sodium salts, such as brine, through the ion exchange resin - a process known as regeneration.

 

Cation resin is a negatively charged matrix with exchangeable positive ions (cations). Negatively charged ions are fixed and permanently attached – part of the resin structure. Because the bead is negatively charged only positive ions are attracted or exchanged.

 

For water treatment purposes cation resin can be purchased in the sodium (Na) or hydrogen (H) forms. Always confirm the resin is in the sodium (Na) form before loading the tank and installing in a home. If hydrogen (H) form is used in a residence the pH of the treated water will be very acidic at 2-3 pH. This is damaging to people and pipes. Hydrogen form cation is required commercially when deionizing or demineralizing water.

 

 

6% – Residential use on well water without chlorine.

8% – Residential or Commercial/Industrial well on city water where 1 ppm or less of chlorine.

10% – Residential or Commercial/Industrial well on city water where chlorine/chloramine levels are greater than 1 ppm. Also used where there is a combination of hot water and oxidants- chlorine or chloramine).

Installation of an activated carbon filter ahead of the softener to remove the chlorine or chloramine will prolong the life of the resin.

 

Water Softeners – Hardness Reduction

Sodium (Na+) strong base cation resin is commonly used for household, commercial and industrial water softening applications. According to the Water Quality Association, water hardness in the United States ranges from 1 to 350 grains (gpg) per gallon or 17.1 to 5,985 ppm. However, most waters range between 3 and 50 gpg.
