The genera of denitrifying bacteria are diverse Paracoccus and Thiobacillus are common denitrifiers in nature.
The multienzyme process of denitrification of wastewater system Knowles Those or- tor DNR of a fertilizer company. Denitrifiers include those that reduce nitrate to N2. It is a selective medium for autotrophic anaero- bic hydrogen oxidizing bacteria, which are denitrifiers. Schematic diagram of the continuous bioreactor system.
Colonies of bacteria showing different morphological features were picked, isolated in pure culture and checked for nitrate reduction un- der aerobic and anaerobic conditions. There was no change in nitrate reduction under either condition. Performance of denitrification in 4-L bioreactor at different tor for the optimization of carbon requirement. Specific denitrifying activity and denitrification effi- The 4-L and L bioreactors were designed as shown in Figure 1.
The influent was fed at the different flow Volumetric denitrification rate rates mentioned in the text. The influent into the reactor was ag- V itated with an overhead agitator at 45 rpm.
Different concentrations of inoculum were taken and checked for their denitrifica- tion activities as a function of time. The studies were Results and discussion carried out at tube level by using effluent as a medium and fusel oil as an electron donor.
Therefore, a consortium of I-4 and m3. Chemically treated effluent, L bioreactor studies. However, complete reduction of which is low in organic carbon, enters DNR-I. While percent SPSS software.
Probability p-value less than 0. The h, then no further decrease in COD was observed. Each experiment was conducted in triplicate in order to Current research work has appreciably validated the role avoid errors. For this purpose immobilized fungus A. Fu and Viraraghavan, ; Knapp and Newby, ; Sumathi and Manju, as the primary dyes removal phenomenon coupled with electrostatic pull between the Treatment of simulated textile effluent containing dye positively charged cell wall and negatively charge dyes Db K2RL with immobilized fungus in shake flasks Aksu et al.
Dyes removal by A. Stirred tank reactor for treatment of Db K2RL with concentration of 10 ppm. We have examined the decolorization of Db concentration of dye from 10 - 60 mgl showing that the K2RL with increasing concentration 10 - ppm.
This happens due to the high dye concentration, due to biosorption alone. A fair amount of research has which may negatively affect the color removal efficiently, been conducted assessing the viability of using sludge to either by exceeding the reactors biological dye capacity treat textile effluents Zissi et al.
Only few studies or by causing toxicity to the biomass Isik and Sponza, have described the successful usage of aerobic sludge for -1 The successful removal of color was dye Reactive blue at times proved to be toxic, thereby reported in a study by aerobic sludge system with color limiting the decolorization activity of Aspergillus spp. Ramya et al.

Biological Treatment of Industrial Wastewater. Many industrial processes use water as a solvent and therefore produce wastewater containing chemicals from that process. The amounts of these chemicals and the types will vary hugely depending on the industry and the processes running and may include things that are hazardous to health or the environment.
This makes. Fundamentals of Biological Wastewater Treatment. This concise introduction to the fundamentals of biological treatment of wastewater describes how to model and integrate biological steps into industrial processes.
