Abstract: In the present study, chromium (VI) was removed using the method called electro-dialysis, and electro-dialysis cum adsorption methods. The experimental investigations have been carried out by using electro-dialysis and electro-dialysis cum adsorption methods for different temperatures and different agitation speeds against different pH. The study compared the results of wastewater treated with electro dialysis method with electro-dialysis cum adsorption method. The validation tests proved that the selected method is having reproducing capacity for removing Cr (VI) from any type of Cr (VI) contaminated wastewater. Finally, this study concluded that the maximum removal of chromium (VI) from tannery industrial wastewater was found with the combination of electro dialysis cum adsorption method than electro-dialysis method alone.

Abstract: The ground water quality was assessed nearby of Pallavaram, Chennai, Tamil Nadu, India. The selected physico-chemical parameters were pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), calcium (Ca) magnesium (Mg), sodium (NA), chloride (CL), nitrate (NO3), sulphate (SO4) and chromium ion (Cr (VI). In order to find out the suitability of the groundwater for drinking purpose, compared the value of selected parameters with the value of selected parameters from BIS drinking water quality standard. The physico-chemical study of the groundwater systems of selected in and around Pallavaram industrial estate showed that groundwater is nearly acidic and mostly oxidizing in nature. Further, the water quality index (WQI) rating was obtained to quantify the overall groundwater quality status of the area. The results indicated that the groundwater is not fit for drinking purpose, and can be used for drinking purpose after treatment.

Abstract: Textile industry processes are among the most environmentally unfriendly industrial processes; because they produce colour effluent that is heavily pollute the environment. Therefore, effluent from textile industry has to be treated before being discharged in to the environment. In this study, experiments were performed to remove the EC, sulphates and COD from the textile industrial effluent in constructed wetlands by using aquatic Macrophytes Lemna gibba L The experiments were conducted by different process parameters like nutrient dosage, dilution ratio, pH and contact time using Lemna gibba L. to reduce EC, sulphates and COD in a textile industry effluent. From the experiments it was found that maximum percentage reduction o various parameters in a textile industry wastewater by Leman gibba L were obtained at an optimum nutrient dosage of 50 g, dilution ratio of 10, pH of 7 and contact time of 6 days. Similarly, the validation experiment is lesser than the maximum removal of sulphate in an aqueous solution. Finally this study concluded that Lemna gibba L. might be used as absorbents for removing various parameters in a textile industry effluent.

Abstract: Textile industry processes are among the most environmentally unfriendly industrial processes, because they produce colour effluent that is heavily polluting the environment. Therefore, effluent from textile industry has to be treated before being discharged in to the environment. In this study, experiments were performed to remove the colour from the textile industry wastewater using coconut coir pith powder as an adsorbent. The experiments were conducted by different process parameters like adsorbent dosage and agitation speed against the pH of 7 and initial concentration of 45 mg/L to reduce colour in a textile industry wastewater. The results showed that the maximum removal of colour occurred for the initial concentration of Acid Orange 10 dye of 11.125 mg/L in a textile industry wastewater found to be 96.3 % and for the actual concentration of 45 mg/L in a textile industry wastewater was found to be 88.6 %. Further, the experimental data were fitted well with pseudo second-order kinetic model than that of pseudo first-order kinetic model for colour by coconut coir pith powder in a textile industry wastewater. Thus, the selected coconut coir pith powder is used in removal the colour in a textile industry wastewater effectively.

Abstract: This paper examines the ability o f polyester fiber reinforced concrete (PEFRBC) to resist the corrosion of reinforcing steel bars in concrete. The corrosion rate of steel embedded in concrete is evaluated in terms of mass loss of corroded steel bars in concrete. The specimens consisted of concrete cylinders measuring 150 x 300 mm with centrally placed 10 mm diameter reinforcing bars. Corrosion of steel bars embedded in concrete having compressive strengths of 20, 25, 30, 35 MPa was investigated. The other parameter varying in this investigation is the percentage of fiber content (0.2, 0.4, 0.6, and 0.8). The specimens are subjected to the accelerated corrosion. Corrosion was induced by means of impressed current. Following corrosion, the rebar were extracted to determine the mass loss. The degree of corrosion of the rebar in the concrete specimens decreased as percentages of fiber content and the grade of the concrete increases. No significant difference in resistance towards corrosion was observed in the higher percentages of fiber contents.

Abstract: Antibiotics and heavy metals resistance profile of Aeromonas species isolated from Kuala Gula and Kuala Sepetang, Perak, was investigated in this study. Isolated Aeromonas species were subjected to 12 antibiotics: Penicillin G 10 units, Tetracycline 30 ?g, Novobiocin 5 ?g, Nitrofurantoin 100 ?g, Ampicillin 10 ?g, Chloramphenicol 10 ?g, Fluconazole 25 ?g, Novobiocin 5?g, Nitrofurantoin 100 ?g and 25 ?g, Kanamycin 30 ?g, and Vanomycin 30 ?g and 5 heavy metals: MnSO4.H2O; Cr (NO3).9H2O; CuSO4; Pb (NO3)2; Hgcl2.Results from this study revealed that-isolates from the two sources-displayed varied resistance. Isolates from Kuala Sepetang showed 91 %, 66 %, 61 %, and 52 % to Vancomycin, Novobiocin, Streptomycin-and Gentamycin while Kuala Gula isolates showed 76 %, 93 %, 28 % and 14 % respectively. High rate of resistance to lead (Pb), Chromium (Cr), copper (Cu) and Manganese (Mn) with minimum inhibitory concentration ranging from 2560 ?g/mL. Low resistance to mercury was observed among isolates from Kuala Gula. This study showed that there was widespread of both heavy metals and antibiotics resistance among Aeromonas isolates in coastal seawater from Kuala Sepetang showing more resistance there by posing danger to both aquatic animals and human health.

Abstract: Although the climate of the Earth is continually changing from the very beginning, anthropogenic effects, the pollution of the air by combustion and industrial activities make it change so quickly that the adaptation is very difficult for all living organisms. Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, o cause damage to the natural environment or built environment, into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth ' s ecosystems. Indoor air pollution and urban air quality are listed as two of the world ' s worst pollution problems n the 2008 Blacksmith Institute World ' s Polluted Places report. Controlling and curtailing air pollution from industrial sources is essential to improve air quality. Industrial sources of air pollution include factories, electrical generation plants and incinerators. Because these sources exist in fixed locations, they are often referred to as ?point sources? to distinguish them from emissions ?mobile sources? such motor vehicles, boats and airlanes.amlai industrial area has also some point sources. The stack & ambient air quality of some locations in the area has been studied in different period of time. High volume air sampler has been used to determine SPM, RSPM, SOx & NOx concentration in the air. Study reveals that the quality of air is not so bad & in under control.

Abstract: Anthracene, a tricyclic aromatic hydrocarbon causes many problems associated with health and environmental impact and serves as a signature compound to detect PAH contamination. Destruction of anthracene molecule in aqueous media or in soil phase without generation of toxic intermediates is a challenging task and the existing physical and chemical treatment facilities are inefficient in the destruction or degradation of anthracene. Microbial destruction, the option available has limitations with bacterial species. The present study emphasizes effective degradation of anthracene by the marine isolates of Bacillus genus. The five marine isolates having different morphological pattern but differ at species level irrespectively showed tolerance towards anthracene at higher concentration (>500 mg/L) and degrade >95 % at concentration <500 mg/L in aqueous medium with in 36 days. The end product of degradation was identified as Octacosane (a linear chain aliphatic molecule) based on FT-IR, and GC-MS spectral analyses. When these species subjected to gene amplifications studies using the primers designed for C23O gene, it is interesting to observe that all the five species displayed the amplified product at 1.3 kb. The study concludes that, marine bacillus sps able to destruct anthracene effectively through its C23O gene.

Abstract: Textile industries are major source of effluents due to their operations. Released colored organic compounds in effluent contaminate the water and are source of non-aesthetic pollution and eutrophication. In the present paper an innovative method is being reported for the decolouration of dyes in textile effluent using photoreduction in presence of solarradiation. Commercial samples of different azo and cremazole textile dyes commonly used in textile industries of Sanaganer region in Rajasthan were used for method development. Photocatalytic activity of titanium dioxide, zinc oxide and manganese oxide was studied in presence of sunlight on commercial dye samples namely Violet, Congo Red, Blue S1 and Orange 3R. The results show that decoloration efficiency of TiO2 is many fold higher than ZnO and MnO. The process shows a significant enhancement when it is carried out at optimum concentration of reducing agent and appropriate time for solar irradiation. 89 % Colour removal from effluent was reached at 96 Hrs operating time.

Abstract: The primary Productivity of phytoplankton of Gogabil Lake, Katihar has been assessed for two years from October, 2009 to September, 2011. The net and Gross Primary Productivity (GPP) was recorded with maximum value of 1.69 gC/m3/d, while the minimum were 0.08 gc/m3/d and 0.42 gC/m3/d respectively. The community respiration ranged between 0.17 gC/m3/d to 1.18 gC/m3/d. The ratio of NPP and GPP fluctuated from 0.11 to 0.91. The P/R ratio was found to vary between 0.12 to 9.96. Net Primary Productivity (NPP) value and P/R ratio indicated eutrophic nature of Gogabil Lake.
