In India, plenty of industrial waste is generated by industrial activity, such as that of factories, mills, and mines. In addition to this industrial waste, municipal limits. This is a major source of environmental pollution and its proper disposal in challenging problems to safeguard the environment for the future generation. The proper utilisation of waste plastic from the industries are suitable for manufacturing of plastic tiles and it will not only bring out the significant saving on the tile material cost but simultaneously shall help in tackling the problem of such waste material.

This paper presents an analysis for the chemical treatment of OBM (Oil Based Mud) used in the drilling process in the oil and gas industry. The analysis is based on OBM stored at ENI (Italian National Energy) gas fields at Bhit mount district Jamshoro since the last ten years that has been chemically and physically deteriorated. Characterization of various OBM samples was performed and these samples were processed in order to evaluate the best characteristics of the OBM for optimum treatment results. The OBM treatment process involves the separation of hazardous fluid (such as diesel or mineral oil) from solids Due to the lean quality of the OBM, the dust separation process in the cyclone caused blockage in the cyclone. This paper suggests a remedial way by means of installation of a hammer stick in the cyclone dust collector to overcome cyclone blockage. The analysis is performed to compare the pressure drop and the dust collection efficiency in the cyclone with and without the hammer stick. The post-installation experimental results showed that hammer stick can improve the cyclone dust collection efficiency without blockage of the cyclone.

A set of indicators for sustainable development were identified to be employed in developing countries. The selected indicators provided a good understanding of social and engineering outputs of a water resources project. Results of the study revealed that there are significant positive impacts of dam construction but they were not same as the targeted objectives envisaged in the feasibility report of the project. It means that after construction of the dam and irrigation system, development didn?t match with the targeted goals of the project. This study argues the world-wide controversy against construction of dam in arid zone which is ill-founded and based on a few short term, mitigable negative impacts, ignoring many positive long term inputs alleviating chronic poverty in arid regions. The study meticulously looks into the pre dam bio-physical and socio-economic conditions in one of the arid region of Iran under the area commanded by Minab dam. This dam was constructed in Hormozgan province of Iran in 1983 and its irrigation system was completed in 1986 which was followed by progressive expansion of irrigated agriculture which almost doubled in year 2006. Literacy rate has increased from 41% (pre-project) to 74% in 2006. Similarly, significant improvements were observed in health care, sanitation, education, and other disciplines.

Assessment of kinetic of AD (Anaerobic Digestion) is a beneficial practice to forecast the performance of the process. It is helpful in the design of AD vessels, substrate feeding and digestate exit systems. The aim of this work was to assess the kinetics of anaerobically digested buffalo dung at different quantities of water added. It comprises the assessment of the specific methane production on the basis of VS (Volatile Solids) added in each reactor by using three first order models, i.e. the modified Gompertz model, the Cone model and the Exponential Curve Factor model. The analysis was tested by using the three statistical parameters, i.e. the coefficient of multiple determinations, the standard deviation of residuals and the Akaike?s Information Criteria. The result reveals that the Exponential Curve Factor model was the best model that described the experimental data well. Moreover, there was not a direct or indirect relation between the kinetic coefficients of the AD process with the varying total or volatile solid content

Background: Bushehr Province has been located in the south west of Iran and due to water shortage crisis in this province, the water quality assessment of its rivers is very important. This study was conducted with the aim of the quality assessment of Shapour, Dalaki, Helleh, Baghan, Mond and Bahoosh in Bushehr Province by using NSFWQI and IRWQISC indexes, because of the importance of these rivers in drinking, agricultural and industrial consumption . Materials and Methods: In this study, water sampling information were taken from 11 stations along 6 rivers including Shapour, Dalaki, Helleh, Mond, Bahoosh and Baghan during 2011-2013. Then, Tthe quality assessment of above-mentioned rivers was implemented by using NSFWQI and IRWQISC indexes. PO4, NO3, DO, BOD, and COD were the parameters that used for the calculation of IRWQISC whereas DO, NO3, PO4, and BOD were utilized for the measurement of NSFWQI index. One way analysis of variance was applied for the comparison of the mean of water quality parameters among different years. Moreover, ArcGIS 10.1 was applied for spatial analysis of water quality parameters and water quality indexes. Results: The results of this study indicated that according to IRWQISC index, Baghan and Dalaki rivers with scores of 31.3 and 39.8 were categorized as bad quality rivers while Shapour, Mond, Bahoosh and Helleh with 46 and 53 scores were included in the average quality category. In addition, with respect to NSFWQI index; Baghan River with a water quality index value of 68 was in the average quality group whereas the rest of rivers with values of 73 and 80 were in the good quality rivers. Conclusion: The findings of this study proved that the of Shapour, Dalaki, Helleh, Mond, Bahoosh and Baghan rivers water were suitable for agricultural purposes while it should be purified for drinking purposes.

In this study, the changes in mechanical, rheological and morphological properties of glass-fiber reinforced poly(oxymethylene) composite after ageing were investigated. Samples were prepared with plastic injection molding method. Ageing process was done by waiting samples at laboratory temperature and water during 28 days. Tensile and 3 point flexural tests were done to determine the mechanical properties, melt flow index (MFI) was measured to determine the rheological property and scanning electron microscopy (SEM) was used to observe the morphological structure. From experimental results, it was seen that mechanical, rheological and morphological properties were affected by the ageing environment. It was found that mechanical properties of aged samples were lower than that of unaged sample. The most decrement in the mechanical properties was occurred at the aged in water samples. Ageing process increased MFI value.

Both temperature and alkaline agent were reported to have effect on solubilizing any possible biomass including organic food waste. The three independent variables considered in this pretreatment were temperature (50-90oC), pretreatment time (30-120 minutes) and alkaline concentration, sodium hydroxide, NaOH (0.7-15 g/L). The maximal condition obtained were 90oC, 15 g/L NaOH for 2 hours. Solubilisation has potential in enhancing methane production by providing high amount of soluble components at early stage during anaerobic digestion.

When water supply systems undergo change, it is necessary to develop new operating rules, which should consider climate, because the climate change is likely to further reduce inflows. In addition, water resource systems are increasingly intended to be operated to meet complex and multiple objectives representing social, economic, environmental and sustainability criteria. This is further complicated by conflicting preferences on these objectives from diverse stakeholders. This paper describes a methodology to develop optimum operating rules for complex multi-reservoir systems undergoing significant change, considering all of the above issues. The methodology is demonstrated using the Grampians water supply system in northwest Victoria, Australia. Initial work conducted on the project is also presented in this paper.
