Pressure filtration of azalomycin broth at acidic pH was studied.1. Filter aid (Radiolite No. 700) needed for adequate filtration rate by filter press was 8% at pH 6.0,4% at pH 4.0 and 2% at pH 2.5.2.Pressure filtration of the broth including 4% Radiolite No. 700 at pH 4.0 could be expressed : θ=0.078ΔP^<-0.28>(V/A)^2+1.6ΔP^<-0.06>(V/A)where θ=time of filtration (min) ΔP=driving force of filtration (kg/cm^2) V=volume of filtrate (cm^2) A=cross-sectional area of filter (cm^3) 3. Specilic resistance, α', of the cake per unit mass of solid in the broth (pH4.0) was expressed as a function of Radiolite No. 700 added.α'=1.1×^<13>x^<-1.40> where x=amount of Radiolite No. 700 added (%) 4. On adding filter aid before pH adjustment (4.0) of broth, specific resistance, α, was 2.0×10^<12>(m/kg), while on adding after pH adjustment, α was 1.4×10^<12>(m/kg).
