Is 25 ppm hard water?
Simply so, what ppm is considered hard water?
The following classifications are used to measure hardness in water: soft 0 - 17.1 parts per million (ppm); slightly hard 17.1 – 60 ppm; moderately hard 60 - 120 ppm; hard 120 - 180 ppm; and very hard 180 or more ppm. What is the treatment for Hardness in drinking water?
is 200 ppm hard water? Hard: 151 – 200 ppm [or 7 – 11 gpg] Very Hard: Over 200 ppm [or over 11 gp **Very, Very Hard: Over 300 ppm [Note: can go as hard as 500 or more ppm] If your water is very, very hard, you will need to do extra filtration of it before you can get good results with your water ionizer.
Similarly one may ask, what level of water hardness is acceptable?
Measures of water hardness General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.
What is the average PPM for tap water?
Concentrations less than 100 ppm are desirable for domestic water supplies. The recommended range for drinking water is 30 to 400 ppm.
