USP-34 Standard Analytic and Twin companies ACH Indicators
USP-34 standard, Al2 (OH) 5Cl.2H2O 12042-91-0 hydroxyl aluminum chloride chemical formula. Theory deserves Al content for 54/210.48 = 25.655% and the Cl content 35.45/210.48 = 16.84%.
USP-34 standard, noted that the standard range for the content is 90% -110%, drawn standard Al content is 23.1-28.2%, the Al2O3 content is 43.63-53.27%, a Cl content of 15.16-18.5%.
Our company’s ACH: Al2O3 content :46-48%; the Cl content :15.8-16.8%. our ACH Higher than usp-34 standard.
50% ACH liquid refers to contain an aqueous solution of 50% of the Al2 (OH) 5Cl.2H2O, USP-34 ACH solution, Al2O3 content 102/210.48/2 = 24.23% theory, Cl content 35.45/210.48/2 = 8.42%. Then on the range of 90-110% of its standard content allows the USP-34 Al2O3 content in the range of 21.81-26.65; Cl content in the range of 7.58-9.26.
Our company’s ACH: Al2O3 content 23-24%; Cl content of 7.9-8.4%, that is higher than the USP-34 standard.
The remaining liquid Fe ≤ 75ppm As ≤ 2ppm, heavy metals ≤ 0.001% the solid Fe ≤ 150ppm As ≤ 2ppm, heavy metals ≤ 0.002% all can find out directly from the USP-34 standard. Standards of Fe in the Fe content is detected in the standard method ultimately is drawn in the color contrast of 75ppm and 150ppm.
The liquid may be used directly metering device according to the experimental dosage inputs required treated water; solids may Ann solids with tap water, pure water, etc.: water = 1:1.5 ratio of about dissolved into a solution, like the use of liquid when ACH may also be specified according to the customer the content of free diluted to the desired concentration before use.
General water treatment dosage
Solid: 20ppm (15-25ppm) or one million tons of water add 20 tons ACH solid
Liquid: 40ppm (30-50ppm) 1000000 tons of water add 40 tons ACH liquid
