The main function of reverse osmosis scale inhibitor is to protect the membrane of reverse osmosis system from scaling and corrosion, and then prolong the service life of the membrane. However, for reverse osmosis scale inhibitor manufacturers, different raw materials for the production of reverse osmosis scale inhibitor will lead to different pH values of water treatment agents, so there will be acidity and alkalinity.
Since there is a difference between acidic and alkaline, we need to know the performance difference between acidic and alkaline reverse osmosis scale inhibitors. At present, reverse osmosis acid scale inhibitors are more popular in the market, but there are also reverse osmosis alkaline scale inhibitors. The acid reverse osmosis agent produced by water treatment chemical manufacturers is mainly used for groundwater, tap water and well water, while the alkaline reverse osmosis agent is mainly used for surface water, river water, seawater desalination and lake water. Reverse osmosis scale inhibitors include a wide range of categories. Each product has its own unique use and market, so it is very popular in the water treatment industry. Reverse osmosis scale inhibitor is a kind of reagent that can prevent membrane surface scaling, improve water production and quality, and reduce project operation cost. So how to choose when using?
1. Consider water quality. If the water quality changes significantly, the reverse osmosis scale inhibitor should be selected with reference to the poor water quality. The water quality changes little. You can choose a more stable water quality and try to buy high-purity products. For wastewater, its water quality changes greatly and contains a lot of dirt. At this time, it is necessary to consider purchasing multiple components of reverse osmosis scale inhibitor and combining the role of each component to achieve the purpose of water purification. The action time of the drug is relatively short, so it is necessary to effectively make the scale inhibitor produce scale inhibitor ions. If the impurity content in the water is too high, its use effect will be affected.
2. Consider purity. For single component reverse osmosis scale inhibitor, the higher the concentration, the narrower the stability interval; vice versa. For the composite scale inhibitor, the stability interval of each component is different, and it is difficult to increase the concentration of the product. In addition, the higher the concentration, the easier it is to change during storage, and the content of impurities in reverse osmosis scale inhibitor will increase.
