the difference between reverse osmosis scale inhibitor and circulating water treatment scale inhibitor

Scale inhibitor refers to a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation, and scaling of insoluble inorganic salts on metal surfaces maintain sound heat transfer effects in metal equipment.

1. How to choose a reverse osmosis scale inhibitor?

When choosing a scale inhibitor, you must first consider the quality of the water to be treated. If the water quality changes significantly, it will be based on the worst water quality. Especially for wastewater, it will be more challenging to remove the water quality. It is required to treat the water discharged into the wastewater system upstream. It is necessary to divide the flow appropriately to avoid notably inferior water from entering the wastewater recycling system to choose the scale inhibitor. For relatively stable water quality, as long as it meets scale inhibition requirements, select products with high purity, extending the cleaning cycle. For the wastewater system, due to its complex water quality, large fluctuations, more scaled components, and prominent trends, it is necessary to consider compound scale inhibitors and use the synergistic effect of each element to improve the overall scale inhibition performance.

2. The difference between reverse osmosis scale inhibitor and circulating water scale inhibitor

Due to the different situations faced by the two, the requirements for the two are additional:

1) The operating environment of the circulating water requires long-term effect and bacteria resistance. A large amount of polymer dispersant can provide suspended solids' dispersion to increase the scale inhibition effect. The circulating water system is extensive in size and operated in the open air. The purity of the agent is required. Not tall.

2) Due to reverse osmosis scale inhibitors' short action time, the scale inhibitors are necessary to interact with scale ions quickly. Besides, because the membrane's internal channels are narrow, polymer dispersants will cause more significant problems. Simultaneously, because the scale inhibition is concentration on the membrane surface, it will also affect the system's stable operation if the impurity content is high.

3) Advantages and disadvantages of the concentration of scale inhibitor

The significant advantage of a high concentration of scale inhibitor is that it can reduce transportation costs. The proportion of transportation costs in product costs has become higher and higher, which has attracted various suppliers' attention. The higher the concentration, the narrower the regular interval for a single dosage form of scale inhibitor. For compound-type scale inhibitors, because every single agent's stability interval is different, it is more challenging to increase the concentration of the product. Besides, the higher the scale inhibitor's attention, the faster it will change during storage, and the content of impurities will increase accordingly.
