The working principle of seed scale inhibition method was expounded. The influences of induced seeds on scaling process were summarized from the aspects of seed crystal type, seed dosing content and liquid supersaturation. The operating temperature, pH, etc. were summarized The induction of crystallization process, the induced seed is a key part of the process, plays a decisive role in scale inhibition. The development and application of the technology of crystallization induced scale inhibition are introduced. According to the specific water quality conditions of seawater, high salt wastewater, industrial wastewater and other treated objects, the development of targeted seed scale inhibition process, and the selection of seed material, dosage, feed solution pH and other process parameters are the seed scale inhibition process The important direction.
