Incomplete Treatment

Heavy metal pollution in wastewater has always been a serious environmental problem because heavy metals are not biodegradable and can be accumulated in living tissues. Copper is widely used in various important industrial applications. The increasing level of heavy metals in the aquatic system due to incomplete treatment of industrial wastewater by existing conventional methods is of environmental concern. Therefore, there has been an increasing interest in the possibility of using biological treatments. It is important to evaluate the performance of biomass with actual industrial effluent to ensure its field applicability. Hence the experiments were conducted with actual industrial effluents collected from Effluent Treatment Plant (ETP) and tannery industry.

Soft drinks industry wastewater from various production lines is discharged into the Industrial Effluent Treatment Plant. The traditional coagulation/flocculation method as first step, followed by biological treatment as second step, has been adopted for treating the soft drinks industry wastewaters. The performance of the plant has been evaluated. It has been found that the effluent characteristics are in most cases in correspondence with the requested standards for discharging the effluent into the Nicosia central sewerage system.

Phytoremediation is one of the best methods in the treatment of sludge from industries because the pollutants present in the sludge are the food source for plants. So, the present study dealt with wedging the electro-plated sludge with red soil for 30 days and using it for the growth of Helianthus annuus L. The sludge and soil were blended in different concentrations C1, C2, C3, C4, C5 and C6 (for the pre-treatment). Physicochemical parameters (pH, ammoniacal nitrogen, potassium and phosphate) and heavy metals (Ar, Cd, Pb, Hg, Ni and Cr) of raw sludge, soil and ETP-treated-sludge with soil were analysed. After inspecting the physicochemical parameters of raw sludge and treated sludge, the soil-treated-sludge was used for the growth of Helianthus annuus L. Phytoremediation by Helianthus annuus L. has made considerable changes in the physicochemical properties of the soil, specially denoting the reduction of chromium. Thus, the work concludes that the pre-treated sludge provides a pathway for the uptake of heavy metals through the process of phytoremediation.

Textile industries are the major contributor to environmental pollution and health hazards by generating huge amount of effluents that contain several pollutants and coloring agents. The concentration of these pollutants can be reduced to the permissible limit with the help of an Effluent Treatment Plant (ETP). The study was conducted to observe the textile effluent management techniques of an Effluent Treatment Plant (ETP) of Fakir Knitwear Limited (FKL), Narayanganj, Bangladesh. FKL set up a biological treatment plant to treat the effluent generated by the industry. Different effluent quality parameters were investigated at different stages in ETP. The effluent of the outlet was dark colored probably because of soluble coloring materials of the effluent but it is comparatively better than that of raw wastewater. There were found higher EC values than the standards which indicated that the greater amount of salts in the water due to dumping of solid wastes and discharging of industrial effluents. The highest TDS value 2054 ppm was observed at the screening pit unit than the other parts of the ETP. The highest DO was found 4.58 ppm in clarification tank which was within the standard value of aquaculture. The study also showed that the lowest BOD (24 ppm) and COD (145 ppm) was found at the outlet which was comparatively better than others. Although the effluent from the outlet contained pollutants, these effluent quality was comparatively good than the untreated waste water discharged from the industry. After treatment, the effluent of outlet moderately ensures the standard quality for aquaculture and irrigation. The results suggested that it is obvious to run the ETP regularly to improve the quality of effluents to save our native environment from the harmful effects of wastewater.J. Environ.

Ammonium Tolerance

A single step process is proposed for ammonium removal from nitrogenous industrial effluents, with a concomitant generation of algal biomass. A microalgal strain found in the effluent treatment plant of a fertilizer industry in Mumbai, India was systematically adapted to remove up to 700 ppm of ammoniacal nitrogen from industrial wastewater, which is nearly four times higher than the ammonium tolerance reported in the literature as well as other algal strains tested in our laboratory. 18S rRNA sequencing revealed the strain to be Chlorella pyrenoidosa. Effects of process parameters such as pH, temperature and light intensity on cell growth and ammonium removal by the adapted cells were studied. Optimal conditions were found to be pH of 9, temperature of 30 °C and a light intensity of 3,500 Lux for the adapted cells.

A small industrial effluent treatment plant has been designed and installed for the treatment of wastewater from a potato chips and snacks factory. The total daily flow rate to the plant was 115 m3/d, while the influent COD mass flux was 838.7 kg/d and the BOD mass flux was 626.7 kg/d. The applied method of treatment is a simple upflow anaerobic reactor with internal settling and gas collection units, followed by aerobic treatment based on the activated sludge process with diffused air system. The quality of the treated water is better than requested and the overall treatment process efficiencies are 99.2% for COD removal and 99.5% for BOD5 removal. The results of the operation of the plant during the first five months are examined and described in this paper.

  Objective: The present study is conducted to investigate the abilities of microorganisms to degrade heavy metals in industrial tannery effluent sample.Methods: Tannery effluent sample was collected from effluent treatment plant and analyzed for physicochemical parameters. The potential microbes were isolated and identified by morphological and biochemical characterization. The sample was analyzed before and after to assess the heavy metal reducing the ability of the microorganism and the respective percentage of reduction were studied using X-ray fluorescence spectrometry.Results: The samples were initially found to be highly contaminated with chromium, nickel, and cadmium. Out of three potential isolates, the isolate Streptomyces sp. was found to exhibit a better reduction against chromium (25.7%), cadmium (14.6%), and nickel (23.1%) in 50 ppm at longer incubation period. Comparatively, the reduction abilities of all the three isolates against all the three heavy metals increased with the increase in the incubation period but decreased with the increase in initial metal ion concentration except in the case of Streptomyces sp. against nickel where the reducing ability increased with the increase in metal concentration.Conclusion: Apparently, the present study revealed that Streptomyces sp. had a better remediation potential than the indigenous Pseudomonas sp. and Aspergillus sp. Ultimately, the finding of this research has shown that the Streptomyces sp. can be used as a potent bioremediation agent for treating tannery and industrial effluent in an eco-friendly process.
