Role of reverse osmosis with scale inhibitor

The purity of water produced by RO reverse osmosis technology is the highest among all water production technologies mastered by human beings at present, and the cleanliness is almost 100%. Reverse osmosis membrane is the key equipment of the reverse osmosis system. When the system operates continuously for a long time, calcium and magnesium plasma in the water will continuously separate out and adhere to the surface of the reverse osmosis membrane, forming scaling and blocking the membrane hole, which will affect the water outlet efficiency of the reverse osmosis system, damage the reverse osmosis membrane, and the reverse osmosis membrane is relatively expensive. Therefore, during the system operation, a dosing system should be added to add reverse osmosis scale inhibitor to the water, Delay the precipitation of calcium and magnesium ions and the scaling of membrane surface. The specific functions are as follows:

Precipitation inhibition function: in the system with scale inhibitor, the ion product value of anions and anions that are easy to scale components at the beginning of precipitation is much larger than the critical precipitation ion product value without scale inhibitor.
Dispersing function: when there is scale inhibitor, it is difficult for the precipitated particles to agglomerate because of their small size. It is more difficult for the precipitated particles to settle than when there is no scale inhibitor.
Lattice deformation effect: the crystals precipitated in the system with scale inhibitor have spherical, polyhedral, snowflake and other amorphous states. It is generally believed that amorphous crystals are crystals with different shapes due to the sharp decrease of the growth rate of the surface due to the adsorption of scale inhibitor on the crystal growth point during the crystal growth process.
Low limit effect: the dosage of scale inhibitor is much lower than that of scaling component in water, and it can also show scale inhibition effect.
