Keywords: Textile Industry Wastewater, Process Parameters.
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.

Keywords: Polyester fiber reinforced blended concrete, Corrosion, Rebar, Impressed current.
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 main objective of this study was to enrich the quality of vermicompost prepared from Paper Mill Waste (PMW) by adding a consortium of microbes. Paper mill waste comprising wood dust, fly ash and sludge from effluent treatment plant were blended with cowdung and vermicomposting done. To this mixture (Industrial Waste Vermi Compost, IWVC) a consortium of microorganisms were added in two stage, i.e. one during the precomposting stage of vermicomposting and other after precomposting for 30 days and vermicomposting for 60 days. The nutritional analysis of both the types of vermicompost were done. From the nutritional analysis, it was observed that the microbial consortia addition was effective after the vermicompost was ready and just before removing the earthworms. Comparison of this enriched compost was made with plain soil and garden waste vermicompost (GWVC) to study the growth of crops like ladies finger and brinjal. Addition after 90 days just before removing the earthworms from the compost proved more effective and the dose of vermicompost @ 2.0 tonnes per hectare gave maximum benefits. Trials were also done using different combinations of vermicompost on the growth of Gaillardia in pots. The addition of live formulates of biological organisms helped n mineralization of immobilized materials improving plant growth.

Abstract: Nano silica is the extremely fine silica that can be used as cement admixture in construction and civil engineering industries. Nano silica can be used to improve slurry impermeability and the mechanical properties of the hardened material. With the adoption of very fine silica particles in cement matrix, porosity and permeability were significantly declined to about 33.3 % and 99 % respectively and compressive strength grew. For conducting this experiment, blended cement has been used. The blended cement used here consists of ordinary Portland cement and flyash replaced to some percentages of cement. The percentage of replacement of fly ash replaced to some percentages of cement. The percentage of replacement of fly ash by cement is about 20 %, 40 %, 60 % and 80 % respectively. Fly ash is a fine, glass-like powdered substance obtained from gases created b y coal-fired electric power generation. Fly ash is an inexpensive substance which is used for replacing ordinary Portland cement in concrete, which thereby improves the segregation, strength and ease of pumping of the concrete. Fly ash is also used as a constituent in brick, block, paving, and the structural fills. Consisting mostly of silica, iron and alumina Fly ash is a pozzolana substance containing aluminous and siliceous material which for m cement in the presence of water. When it is mixed with lime and water they form a compound similar to Portland cement. The spherical structure of the particles reduces the internal friction thereby increasing the consistency and mobility of the concrete, allowing longer pumping distances. Increased workability means less amount of water is required, thus resulting in less segregation of the mixture. Even though fly ash is less dense than Portland cement, the produced concrete will be denser and results in smooth surface with sharper details. Class F of Fly ash, in which particles are covered in a kind of melted glass, greatly reduces the possibility of expansion due to sulfate attack, as may occur in fertilized soils or near coastal area. We have chosen Class F fly ash for replacing cement.

Abstract: The study aims at describing the physico-chmical parameters of the influent and outlet water of the Nesapakkam sewage treatment plant, which were analysed during May, 2013 to Jan, 2014 in order to capture both the Summer and Winter seasons. The efficiency of pH, Total Suspended Solids, Chemical Oxygen Demand (total), Chemical Oxygen Demand (soluble), Biochemical Oxygen Demand (total) was significant. The sewage treatment plant system using different materials showed excellent potential for pH, Total Suspended Solids, Chemical Oxygen Demand (total), Chemical Oxygen Demand (soluble), Biochemical Oxygen Demand (total) removal from sewage treatment plant. The result of analysis of treated water pH, Total Suspended Solids, Chemical Oxygen Demand (total), Chemical Oxygen Demand (soluble), Biochemical Oxygen Demand (total) indicate that the trial treated water can be used for industrial cooling and agricultural purposes. Treated water from sewage treatment plant was alkaline, PH of the effluent increased marginally after the treatment. Average removal efficiencies of measures parameter from treated water 68.98 % for Total Suspended Solids, 84.18 % for Biochemical Oxygen Demand, 87.64 % for Chemical Oxygen Demand. These values are higher than values obtained for the summer season. During the winter season 84.23 % for Total Suspended Solids, 78.38 % for Biochemical Oxygen Demand, 80.02 % for Chemical Oxygen Demand. These values are lower than values obtained for the summer and rainy seasons, except Total Suspended Solids, 78.38 % for Biochemical Oxygen Demand, 80.02 % for Chemical Oxygen Demand. These Values are lower than values obtained for the summer and rainy seasons, except Total Suspended Solids.
