BIS Standard says that the maximum desirable TDS is 500 mg/L and the maximum permissible level in the absence of a better source of water is 2000 mg/L. A related standard is the ‘hardness measured as CaCO3′′ where the acceptable limit is 200 mg/L and maximum permissible is 600 mg/L.
What is the allowable limit of hardness in water?
The membrane manufacturers will often specify what the maximum hardness concentration can be, but industry rule of thumb is that hardness should not exceed 120 to 170 mg/L (7 to 10 grains per gallon) .
Is it bad to have high chloride?
An excess of chloride in your body can be very dangerous because of the link to higher than normal acid in the blood. If it isn’t treated promptly, it can lead to: kidney stones. hampered ability to recover if you have kidney injuries.

Can we drink 400 TDS water?
Generally, the TDS level between 50-150 is considered as the most suitable and acceptable. ... Bisleri water maintains a TDS level of upto 120 PPM, making it safe to drink.
What is unit of hardness?
The SI unit of hardness is N/mm2 . The unit Pascal is thus used for hardness as well but hardness must not be confused with pressure. The different types of hardness discussed above have different scales of measurement.
What is a good level of water hardness?
An acceptable level range for water hardness is going to be 100- 300 PPM depending on what city you live in and what the water treatment plant has decided on.
What is normal water hardness?
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. Lime scale buildup inside a water pipe.
