Activated Alumina Balls
White bead, non-toxic, odorless and insoluble in water and ethanol. According to different uses, its raw materials and preparation methods are different.
Application:
Particle size: The smaller the particle size, the higher the adsorption capacity, but the smaller the particle size, the lower the particle strength, affecting its service life.
PH value of raw water: When the PH value is greater than 5, the lower the PH value, the higher the adsorption capacity of activated alumina.
Raw water alkalinity: High bicarbonate concentration in raw water will reduce the adsorption capacity.
Chloride ion and sulfate ion.
