Product Details

Lanlang ® TC010FG Is a premium food grade gel type strong acid cation exchange resin produced by sulfonated styrene-divinylbenzene (DVB) copolymers with high cross linkage at 10%. Its high cross linkage makes it has excellent resistance to attrition and oxidative degradation. TC010FG is in compliance with US FDA 21 CFR 173.25 and NSF/ANSI 61 qualified with WQA Gold Seal Certificate. It has excellent chemical, physical and thermal stability, and high exchange capacity. Its good ion exchange kinetics gives high efficiency for uses in both regenerable softeners and non-regenerable cartridges.


How is Hard Water Measured?

Water hardness is measured in grains per gallon (gpg) and in part per million (ppm) or milligrams per liter (mg/L). One grain per gallon is equal to 17.1 ppm or mg/L. Below is a classification of water hardness.

Soft Water

0 to 3.5 grains per gallon

0-60 ppm

Moderately Hard Water

3.5 to 7 grains per gallon

61-120 ppm

Hard Water

7 to 10.5 grains per gallon

121-180 ppm

Very Hard Water

Over 10.5 grains per gallon

Over 180 ppm

Water can be tested using water hardness kits such as test strips, titrates, and various digital handheld testers. Once the hardness is known, one is able to calculate the capacity of the cation exchange resin. Capacity is determined by water hardness, salt dosage and the amount of cation resin used. Salt dosage equals the following capacities in grains.

6 lbs. of salt per cubic foot of resin

20,000 grains

8 lbs. of salt per cubic foot of resin

22,500 grains

10 lbs. of salt per cubic foot of resin

25,000 grains

12 lbs. of salt per cubic foot of resin

27,500 grains

15 lbs. of salt per cubic foot of resin
