Underwater Pelletizing

Does Underwater Pelletizing reduce dust emissions or wastewater production?
During the operation of the underwater granulator, after the molten material is cut into particles at the die head, it immediately enters the water for cooling and shaping. This entire process is carried out in a closed environment, which effectively isolates the material from direct contact with the outside air, thus greatly reducing the generation and emission of dust.
In the traditional granulation process, powdery materials are prone to dust during transportation, storage and processing. Underwater Pelletizing technology converts powdery materials into granules. The granular materials are less likely to raise dust, reducing the generation and spread of dust. This change in physical form fundamentally reduces the risk of dust emissions.
Due to the closed nature of Underwater Pelletizing technology and the change of material form, it has significant advantages in environmental protection. For occasions where dust emissions need to be strictly controlled, such as chemical, pharmaceutical, food and other industries, Underwater Pelletizing technology provides a more environmentally friendly and reliable solution.
Underwater Pelletizing technology usually uses a circulating cooling system to cool and shape the cut particles. This means that cooling water is reused throughout the system, reducing the need for fresh water while also reducing the amount of wastewater produced.
Although Underwater Pelletizing technology reduces the generation of wastewater, a certain amount of wastewater may still be generated in actual operations, such as during equipment cleaning and maintenance. However, these wastewaters can usually be treated and reused through appropriate wastewater treatment processes, such as using physical, chemical or biological methods to remove suspended solids, organic matter and other pollutants in wastewater, thereby achieving wastewater discharge or reuse up to standard.
Underwater Pelletizing technology reduces the generation of wastewater from the source by optimizing process parameters and equipment design. For example, by precisely controlling cutting parameters and cooling conditions, the loss and waste of materials during the cutting and cooling processes can be reduced, thereby reducing the amount of waste water generated.
Underwater Pelletizing technology effectively reduces dust emissions and wastewater production through its unique operating methods and changes in physical properties. This technology has significant advantages in environmental protection and is of great significance in promoting green manufacturing and sustainable development.
