Abstract

Absorption of active dyes with Azo base (Active Red) is made by passing from dried ACTIVE SLUDGE. During performed tests, which was with changing of initial pH-gram of adsorbent matter -changing in shaker speed and initial dye concentration as well as investigation of kinetic changes and their effects on absorption rute show that equilibrium models follow from detailed equation of Freundlish & Longmuir well. the highest percent of absorption which obtained in these testes for the color of active red in concentration of 40 mg/lit is equal to 61.12% with absorbed gram 2.5 in pH=2. Adsorption stage of AZO DYEs follows the second-degree kinetics and it was specified that the capacity of adsorption is relatively high. (pH<6) The high correlation coefficient, R>0.989, showed that this method is suitable.The adsorption method was used for absorbance of dyes the bucteries in the sludge were subject to growth, then it was dried for 24 hours fewer than 60o c.
