The specific mechanism of action of cellulose filter aids in the filtration process mainly includes the following points:
Increase the porosity of the filter media: Cellulose filter aids can be filled in the pores of the filter media to play a filling role, increase the porosity of the media, and improve the permeability and filtration efficiency of the filter media.
Increase the surface area: The cellulose filter aid itself has a large specific surface area, which can increase the surface area of the filter medium and improve the filter medium's ability to capture particulate matter.
Capturing particulate matter: The fiber structure of cellulose filter aid and its surface characteristics can adsorb particles, microorganisms, colloids and other impurities suspended in the water, and play a role in filtering and cleaning water quality.
Improve filter media performance: Cellulose filter aids can improve the physical properties of filter media, increase the mechanical strength and stability of the media, and extend the service life of the filter media.
Promote the formation of filter cake: Cellulose filter aids can promote the formation of filter cake during the filtration process, improve the solid-liquid separation effect, and reduce process resistance and time costs in subsequent processing.
Reduce clogging and clogging: Cellulose filter aids can reduce clogging and clogging of the filter media caused by the accumulation of particulate matter and maintain stable filtration efficiency.
Improve filtration efficiency: The role of cellulose filter aids can improve filtration efficiency, accelerate the solid-liquid separation process, reduce the content of suspended matter in the water, and improve the purity of water quality.
Through the above mechanism of action, cellulose filter aids play a role in increasing the porosity and surface area of the filter media, capturing particulate matter, promoting filter cake formation, and reducing clogging and clogging during the filtration process, thereby improving filtration efficiency and Water purification effect.
