The paper provides a critical comparison between mesophilic and thermophilic anaerobic treatment of PTA wastewater through diagnosis of a case study. Aspects covered are bioavailability, biodegradability, microbial population, thermodynamics, kinetics involved and bioreactor design for PTA wastewater treatment. The results of the case study suggests that onestage thermophilic anaerobic reactor ...

The present study was conducted to evaluate the potential applicability of biological trickling filter system for the treatment of simulated textile wastewater containing reactive azo dyes with bacterial consortium under non-sterile conditions. The percentage decolorization for the treatment of wastewater containing structurally different dyes was found to be higher than 95% in all trials. The ...

Abstract Industrial effluents containing appreciable amounts of phenol and formalin may represent a problem when these effluents undergoing biological treatment. Experience in field of biological treatment for wastewater contains high concentrations of formalin showed high inhibition effect of formalin to biodegradation, specifically at higher concentrations more than 225 mg/L [3]. Also, as phe...

This paper presents a case study on application of photosynthetic bacteria wastewater treatment system to recover organic carbon in wastewater in the form of photosynthetic bacterial cells. In noodle production process, the wastewater was mainly produced during rice soaking and rinsing processes containing starch as its main constituent. For carbon recovery purpose, wastewater was applied to la...

Laboratory strains of Escherichia coli containing plasmid pBR325 (or pBR322) were coincubated with a mobilizer strain of E. coli (containing the conjugative plasmid R100-1) and a recipient strain of bacteria. Bacterial strains isolated from raw wastewater or a plasmid-free E. coli laboratory strain served as recipients. Transfer of the pBR plasmid into the recipient strain occurred during a 25-...

The element phosphorus (P) is essential to all life (e.g. plants, animals and bacteria) and is a key ingredient in fertilizers to sustain high crop yields. However, the lifetime of exploitable reserves of natural ore deposits containing P is estimated to range from the next few decades to several hundreds of years, since P is intensively used in agriculture and other industries. The use of P yi...

This study investigated the effects of the electrolytic treatment in the simulated wastewater with aromatic amine nphenyl-n-isopropyl-p-phenylenediamine (Flexzone 3P) using Ti/TiRuO2 electrodes under 0.025 A/cm 2 (DC) for different electrolysis durations (5; 15; 30; 45 and 60 min). Conductivity, pH, UV-visible spectra, gas chromatograms, toxicity and biodegradation tests were carried out. Durin...
