Preparation and Performance Test of Composite Clinoptilolite Filter Material
Spheroidal composite filter material was made with activated clinoptilolite powder as the main stuff. The best condition of the process determined by orthogonal test were ωclinoptilolite: ωbond: ωadditive=55%:35%:10%, activation temperature at 150 ,activation time at 3h. The piled density, compressive stress and apparent porosity of the composite filter materials are 674Kg/m3, 4.32MPa and 59.02%. Compared with ceramsite and natural clinoptilolite, the composite filer materials has larger specific surface area and higher poriness, so it can be well used in BAF.
