Sore Throat And Cough With Menstruation

When faced with calculating housing needs or group homes or
any other case, to reduce water hardness , we will have many questions:

• We have no idea of \u200b\u200bchemistry.
• I do not know what is the hardness
• I do not know how a softener works.
• is the first time I hear of ion exchange.
• What are exchange resins?
• Why are cationic and / or anions and the words mean?
• I looked at the catalog price and there are plenty of models and all seem the same.

Etc. At this point the despair is total, and nothing is further from reality, it is true that there are technical
have answers to all questions above and many more,
but is necessary to have all responses to calculate a softener ?:
Absolutely NO.

Obviously we need to know multiplication and division, and calculators that are available, and lack
also makes a series of instructions that can be followed without
understanding them or understand them better first, if we're going to try to sell a water softener
someone who "says" have problems hardness in your water, then something must be known, and that we will
try to do with this little manual.

The reader must flee to ask why?, As coach, if you fill the
patient head, and if it is "normal" will say "because I say so."
The hardness is a parameter that we measured the calcium content in water, water with high calcium
be a hard water, and decalcified need.

next thing we need to know and remember is that the hardness is usually measured in degrees
French and denote this (No HF) and today, and to unify criteria (as there are degrees
German, English ...) is being measured in parts per million
calcium carbonate, which typically represent you well.
