WHAT’S IN WATER

C. WATER TESTING

Water testing is necessary to determine the amount of minerals in a water supply that affect ice

and the ice maker.

T.D.S. (Total Dissolved Solids) is the test for the total

concentration of all minerals present in the water.

Chlorides Are tested to determine the degree of cloudy ice and

Alkalinity scale build-up.

Total Hardness

Small concentrations of minerals do not affect the ice quality or cause excessive scale build-up.

However, amounts which have an adverse effect are:

EFFECT EFFECT

TEST CONCENTRATION ON ICE ON ICE MAKER

T.D.S. 50-1000 ppm Cloudy Temporary and

or higher slow cutting permanent scale

refreezing build-up

Chlorides 200-300 ppm Major cause of Temporary and

or higher cloudy ice, permanent

slow cutting, build-up

refreezing

Alkaloids 300-400 ppm Cloudy Temporary and

or higher slow cutting permanent

refreezing scale build-up

Total 5-10 GPG* Clear ice Minimum scale

hardness (100-170 ppm) build-up

10-15 GPG Slightly cloudy Moderate scale

(170-255 ppm) build-up

15-20 GPG Noticeably cloudy Serious scale

(255-340 ppm) possibly slow cutting build-up

and refreezing

20 GPG and up Severely cloudy Excessive scale

(340 ppm and up) Slow cutting build-up

Refreezing

*Grains/Gallon

Water treatment companies usually have the equipment to test water. Most city water

departments can supply information concerning the mineral content in the water.
