The formula of reverse osmosis scale inhibitors can vary depending on specific products and application requirements. The following is an analysis of a common reverse osmosis scale inhibitor formula, which includes several commonly used components:
Phosphate compounds: such as sodium tripolyphosphate or tetraphosphate. Phosphate compounds can form complexes with metal ions such as calcium and magnesium in water, preventing their deposition on the surface of reverse osmosis membranes and thereby reducing scaling.
Chelating agent: such as nitrite or ethylenediaminetetraacetic acid (EDTA). Chelating agents can form stable complexes with metal ions in water, causing them to lose their ability to scale.
Corrosion inhibitor: such as sodium thiosulfate or benzotriazole. Corrosion inhibitors can reduce the redox potential of metal ions, slow down the electrochemical reaction rate of metal ions, and thus reduce fouling on the membrane surface.
Dispersant: such as sodium polyacrylate or sodium carboxymethyl cellulose. Dispersants can prevent the aggregation and deposition of scaling substances, keep them in a dispersed state, and reduce pollution to the reverse osmosis membrane.
It should be noted that the above ingredients only list a few common components of reverse osmosis scale inhibitors, and it does not mean that all formulas will contain these ingredients. The actual product formula may be adjusted and optimized according to specific needs to meet specific scale inhibition effects and usage conditions. When using reverse osmosis scale inhibitors, please follow the instructions and safety operating procedures provided by the manufacturer to ensure proper use and storage.
