Abstract
To provide design data applying to the treatment of wastewater from dispersed dye factories, an experimental study was undertaken using bench‐scale completely mixed activated sludge reactors fed with dispersed dye factory effluent as a substrate. Kinetic coefficients were determined at different hydraulic retention times and compared with published data for other substrates. The results showed that when biochemical oxygen demand (BOD) was utilized as a measure of substrate concentration, the values obtained for the substrate removal rate coefficient k =0.00063 L/mg BOD‐hr, sludge yield coefficient Y=0.26 kg MLVSS yield/kg BOD removed, and sludge endogenous decay coefficient K d =0.003 I/day.
