An example for the dilution of a <br />high nitrate water with a water of lesser nitrate concentration to obtain a <br />value of acceptable level is given. <br /> <br />Dilution equations for mixing of two water supplies <br /> <br />CIVl + CZVZ <br />Vl + Vz <br /> <br />C3 <br /> <br />v +v =V <br />I Z Total <br /> <br />e.i. nitrate eonc. supply 01 5 mg/L <br />nitrate conc. supply Oz = 17 mg/L <br />want mixed water conc. = 9.0 mg/L <br />want final mixed water volume of 10 M.G. <br /> <br />SVl + 17VZ <br />10 MG <br /> <br />9.0 mg/L <br /> <br />. <br /> <br />VI + Vz = 10 MG <br />5 (10-VZ) + 17VZ a 90 <br /> <br />50 - 5VZ + 17VZ <br />12VZ = 40 <br /> <br />90 <br /> <br />v = 3.33 MG <br />2 <br />Vl = 6.67 MG <br />10.00 MG with nitrate conc. of 9.0 mg/L <br /> <br />Jim Krause <br />Chemist <br /> <br />.'i- <br />
