Three factors affecting the effect of anti permeability and scale inhibitor

2016-02-19 22:24:39

        There are many factors that affect the scale inhibition effect of reverse osmosis scale, and each factor has a large variation range. Under general conditions, scale inhibitors have different effects on the scale and dispersion effects of different conditions. Let's learn it together:
        First, the influence of iron ions
        Reverse osmosis inhibitor effect of the water cycle often due to metal corrosion of the iron ion concentration was increased, especially the use of strong corrosive water quality of circulating water system and system of leakage of material, the concentration of iron ion sometimes as high as 5mg / L. iron ion of all elixirs resistance calcium phosphate scale has great influence, with the increase of the concentration of iron ions, inhibiting calcium phosphate scale effect is greatly decreased.
        Two, the effect of calcium hardness and alkalinity
        In practice, it is found that the effect of calcium hardness and alkalinity in water on scale inhibition and dispersion is great. The scale inhibition rate decreased with the increase of calcium hardness and alkalinity, but the influence degree was not the same. Compared with calcium carbonate, calcium hardness and alkalinity in water are more affected by the effect of calcium carbonate. In addition to the effect of calcium phosphate on the drug resistance is relatively small these agents on calcium phosphate almost completely lost the role of scale inhibition.
        Three, the effect of fungicides
        The concentration of the reagent is one of the factors that affect the effect of scale inhibition and dispersion. The influence of calcium carbonate and calcium phosphate is different, there is a low concentration of calcium phosphate, and only the concentration of the reagent is more than the lowest concentration. The effect of turbidity on the scale inhibition and dispersion was affected by different degree, but the effect of calcium phosphate was greater, and the effect of calcium phosphate decreased significantly with the increase of turbidity. The effect of iron ion on the scale inhibition and dispersion effect is obvious, whether it is the calcium carbonate or calcium phosphate calcium carbonate, it is with the increase of iron concentration, the effect of scale inhibition and dispersion decreased.
