4040 FR Low Pressure Water Purifier of Reverse Osmosis RO Membrane Element
Hydrochloric acid (HCl) and sulfuric acid (H2SO4) can be added to the influent water to lower the pH. Sulfuric acid is cheap, does not fumes and corrodes surrounding metal components, and the membrane has a higher removal rate of sulfate ions than chloride ions, so sulfuric acid is more commonly used than hydrochloric acid. Industrial grade sulfuric acid without other additives is suitable for reverse osmosis. Commercial sulfuric acid has two concentration specifications: 20% and 93%. 93% sulfuric acid is also known as 66 Baume degree sulfuric acid. Care must be taken when diluting 93% sulfuric acid, heating to 66% can raise the temperature of the solution to 138°C. Be sure to add the acid slowly to the water with stirring to avoid localized boiling of the aqueous solution. Hydrochloric acid is mainly used when calcium sulfate or strontium sulfate scaling may occur. The use of sulfuric acid increases the sulfate ion concentration in the reverse osmosis influent, which directly results in an increased tendency for calcium sulfate scaling. Industrial grade hydrochloric acid (without additives) is very convenient to buy, and the general content of commercial hydrochloric acid is 30-37%.
The primary purpose of lowering the pH is to reduce the propensity of calcium carbonate scaling in the RO concentrate, ie to lower the Langerial Index (LSI). LSI is the saturation of calcium carbonate in low salinity brackish water, indicating the potential for calcium carbonate scaling or corrosion. In reverse osmosis water chemistry, LSI is an important indicator to determine whether calcium carbonate scaling will occur. When the LSI is negative, the water will corrode metal pipes, but will not form calcium carbonate scale. If the LSI is positive, the water is not corrosive, but calcium carbonate scaling occurs.
