Copper Sulfate Dosing

The desired copper sulfate dosage may be expressed in three different ways, as indicated below:

Given mg/L Copper

First calculate the lbs copper (Cu) required: https://www.w3.org/1998/Math/MathML">(mg/L Cu) (MG Vol.  of  Reserv. )  (8.34  lbs/gal)  =  lbs  Cuhttps://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429152870/f723f148-e268-4171-8927-ab255829852a/content/eq544.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>

Then determine the lbs of copper sulfate pentahydrate (CUSO4 • 5H2O): (This compound contains 25% copper.) https://www.w3.org/1998/Math/MathML">lbs  Cu% Copper100=lbs CuSO4  ·  5H2Ohttps://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429152870/f723f148-e268-4171-8927-ab255829852a/content/eq545.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
