Kain Industrial Additives: How to choose a suitable reverse osmosis scale inhibitor

Many factories use reverse osmosis scale inhibitors because they can increase water production and water quality, thereby reducing costs. However, many people do not know how to choose reverse osmosis antiscalant and what kind of reverse osmosis antiscalant to choose to get the best effect. To this end, Kain has summarized several methods for selecting reverse osmosis antiscalants for your reference.

First, consider water quality. If the water quality changes significantly, the reverse osmosis antiscalant should be selected based on the worst water quality. As far as the selection of reverse osmosis antiscalants is concerned, the water quality does not change much. Just choose a relatively stable one that meets the requirements. Try to buy high-purity products. For wastewater, the water quality changes greatly and contains a lot of dirt. At this time, it is necessary to consider purchasing a reverse osmosis antiscalant with multiple components, and use the combined effect of each component to achieve the purpose of water purification. The action time of reverse osmosis anti-scaling agent is relatively short, so it is necessary to quickly and efficiently react with the anti-scaling agent and scaling ions. If the impurity content in the water body is too high, it will also affect the effectiveness of the reverse osmosis antiscalant.

Secondly, consider purity. For single-component reverse osmosis antiscalants, the higher the concentration, the narrower the stability range; for compound reverse osmosis antiscalants, the stability range of each component is different, making it difficult to improve the product’s stability. concentration. In addition, the higher the concentration of reverse osmosis antiscalant, the easier it is to change during storage, and the content of impurities will also increase.

In addition, understanding the types of reverse osmosis antiscalants is also very necessary for us to choose reverse osmosis antiscalants. Common reverse osmosis scale inhibitors include polyphosphates, polycarboxylic acids, etc. Each reverse osmosis antiscalant exhibits different scale removal properties. In recent years, many phosphorus-free antiscalants and reverse osmosis antiscalants without any environmental pollution have also been launched. The purpose is to reduce the massive death of fish and shrimp caused by phosphorus-containing reverse osmosis antiscalants and the rapid proliferation of algae-rich water bodies. nourishment phenomenon.
