Εμένα Γιάννη (και) αυτό με μπέρδεψε :
Παράθεση:
I would rephrase that definition  .
Carbonate Hardness = Temporary Hardness = Water Hardness produced by
carbonates and bicarbonates of calcium and magnesium = Total Hardness -
Permanent Hardness.
KH: German for carbonate hardness?
Yes -- Abbreviation for "Karbonathaerte"
Non-carbonate hardness: General hardness - Carbonate hardness????
Right. It is the same as "Permanent Hardness" = water hardness produced
by salts of calcium and magnesium OTHER THAN carbonates and
bicarbonates, i.e. sulfates, chlorides, etc.
Does anyone disagree with any of these definitions????
