Subject: Characterization and effective utilization of caol ash with geosynthetics in pavement subgrade
Keywords: Black cotton soil, Geosynthetics, waste coal ash, optimum moisture content, maximum dry density, unconfined compressive strength, Clifornia bearing ratio (CBR)
Abstract: Pavements on black cotton soils fail during adverse weather conditions due to swelling and shrinkage characteristics of such soils, Stabilization of black cotton soils, therefore, becomes mandatory. Geosynthetics are soil stabilization materials used to improve soil conditions in various applications. Cash ash is available at low cost and it is utilized for the stabilization of black cotton soils. The present study aims to utilize coal ash effectively in pavement subgrade. In phase of the research, index and engineering properties of virgin soil is studied, and the soil is classified under CH (clay of high compressibility) category. Coal ash is added to the soil by10%, 20%, 30%, 40%, 50% replacements to the weight of soil. The shear strength of virgin soil is 90.60 mN/m2 at an optimum moisture content of 21% and maximum dry density of 1.6807 g/cc. The california bearing ratio 9CBR) values of the virgin soil under soaked and soaked conditions are 5.33 % and 2.84 %, respectively. This study shows that the shear strength, optimum moisture content, maximum dry density is maximum at an optimum of 10% addition of coal ash to the soil. Atterbergs limits and plasticity index decreases with the addition of coal ash.

Keywords: Stress rupture,Fireside corrosion, Corrosion fatigue failures, Soot blower erosion, material defect and weld defects
Abstract: According to National thermal power corporation (NTPC) reports, in the NTPC Unchahar power plant in Raebareli district started generating power in 1988 with five units of 210 Mw each, an extremely high-pressure explosion occurred because of ash within the boiler furnace caused it to leak, producing a disaster. The blast was reportedly triggered in the duct connected to the boiler which is used for transferring ash of burnt coal. It is believed that the ash pipe got choked, leading to the blast. The boiler pipe burst in the 500 Mw power generating unit that started operating in March at the plant in Unchahar, which is nearly 30 years old. A massive fire broke out and a huge ball of dust rose after the explosion, making rescue difficult. According to NTPC reports, there was sudden abnormal sound at 20 m elevation and there was an opening from which hot flue gases and steam escaped affecting the people working around the area. This paper highlights the importance of boiler tube leakage on the performance of the thermal power plant. This paper also suggests various controlling mechanisms towards enhancing energy efficiency in thermal power plants.

Subject: Removal of organic pollutants from coffee wastewater : A mini-review
Keywords: Coffee processing wastewater (CPWW), organic pollutants, treatment technologies
Abstract: The coffee industry utilizes large quantities of water during the various stages of the production process. Consequently, the amount of wastewater generated is high that contains high concentrations of organic matter, nutrients, suspended matter and highly acidic. The effluent discharged unwisely into nearby natural water bodies which flow into rivers and/or infiltrate into groundwater become the main threat to the quality of surface and ground water. Hence there is a need to curb this problem through innovative and eco-friendly techniques. Understanding the coffee processing and nature of the coffee processing wastewater is fundamental for the design and operation of appropriate and effective treatment technologies. This review presents the various treatment techniques adopted and also various research conducted on the removal of organic pollutants from coffee processing wastewater (CPWW). In addition, the scope for biogas production from the wastewater treatment is highlighted.

Subject: Pyrolysis temperature effects on yield, physico-chemical characteristics of pine-bark biochars and cadmium sorption
Keywords: Biochar, cadmium sorption, human faecal, pine-bark, pyrolysis temperature
Abstract: Globally, tonnes of bark wastes are disposed of by timber production industries annually. Pyrolysis of the bark could be viable waste managemnt option where the biochar could be used as sorbents of pollutants in wastewater and in agricultural applications, depending on their properties that are known to depend on carbonization processes. The objective of this study was to determine the effect of pyrolysis temperature on yield and physico-chemical characteristics and cadmium sorption of biochars carbonized from pine-bark. The biochars were produced by slow pyrolysis at 350˚C, 550˚C and 650˚C and were analysed for yield, ash content, fixed carbon, total carbon, nitrogen, and hydrogen content and surface characteristics. Sorption of cadmium was studied using a laboratory batch experoment with the three biochars with solutions of increasing cadmium concentrations. The adsorption data were fitted in best fitting Langmuir isotherms. Biochar from pine-bark showed a more porous structure when pyrolysis temperature was increased. Sorption capacities increased with pyrolysis temperature. The findings imply that pine bark biochar could be a low-cost adsorbent from cadmium from wastewater and the effectiveness could be increased by higher pyrolysis temperatures and furthermore, cadmium sorption efficacy of pine-bark may be improved by incorporation of human faecal waste derived biochars.

Keywords: Water quality index, Sub-index, quality rating, relative weight, standard limit, contamination
Abstract: In order to provide optimal growth of fishes and prawn with high stocking density in the small area, various artificial inputs in the form of feed, fertilizers and drugs are essential. These are added regularly in aqua ponds as food, to kill predators and control of diseases. The organic load in terms of unutilized fee due to excessive feeding. Faecal matter released by fish or load in terms of unutilized feed due to excessive feeding, faecal matter released by fish or prawn, dead algae, etc., which are rich in proteins and carbohydrates settle at the bottom of pond and contribute pollution. During harvesting of the crop, the ponds contaminated water is emptied either into the canal or surrounding water bodies of good quality of water. These activities investigate the pollution in ponds and increase total dissolved solids (TDS), total suspended solids 9TSS), chemical oxygen demand 9COD) and biochemical oxygen demand (BOD) in aquaculture water in turn surrounding surface and groundwater. Local people are struggling a lot for drinking water, in spite of plenty of water is available in coastal regions. Keeping the above points in view, an attempt has been made to study the level of contamination in fish and drinking water ponds at Nandivada Mandal, Krishna district, Andhra Pradesh and to warn the local Government and people against intensive aquaculture. During the study period (2016), 17 samples were collected from seven villages of Nandivada Mandal and analyzed for various parameters, such as dissolved oxygen (DO), biochemical oxygen demand 9BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), turbidity, pH value, total alkalinity, total acidity, total hardness and chlorides. The analyzed data has been used to find water quality index (WQI).The water quality index calculated in this work is composed of eight measurable parameters. High concentrations of biochemical oxygen demand, chemical oxygen demand and total suspended solids were recorded both at fish and drinking water ponds. The water quality index at all locations were much more than 100.It is evident from the present investigation that he degradation of water quality in this watershed is due to aqua culture activity.

Keywords: Activated sludge height, anaerobic baffled reactor (ABR) , down-upflow, ketchup, synthetic wastewater
Abstract: The ketchup home industries generate unique wastewater and discharge it to the water body without prior treatments. This situation is mainly caused by the lack of working capital, land area, environmental awareness and skills. The objective of this research is to investigate the effect of the height of the activated sludge on the performance of anerobic baffled reactor (ABR) and to contribute knowledge on efficient and applicable wastewater treatment to the home. The synthetic wastewater used in this research was the imitation of ketchup wastewater of Superindo brand. The anerobic baffled reactor has 3 pairs down and up-flow sections with total volume of 60 L. Active sludge of 30, 40 and 50% of the height of the anaerobic baffled reactor were employed in this research. The best result was obtained when activated sludge of 50 % height was used in the anaerobic baffled reactor system which chemical oxygen demand (COD) removal was higher than 80%, stable of pH and least suspended solid for three days treatment.

Subject: Effect of sand addition on the mechanical properties of pervious concrete
Keywords: Pervious material, Flyash,admixture, compressive strength, permeability
Abstract: In many developed countries the use of pervious concrete for the construction of pavements, at car parks and driveways is becoming popular day by day. Pervious concrete provides a sound solution for managing storm waters in built-up environments where the water runoff, as well as the natural recharge of the groundwater is an important issue. The use of pervious concrete has also been commonly related to other environment al benefits, such as the urban heat island reduction, control surface pollutants and traffic noise adsorption. The performance of pervious concrete can be enhanced by adding a small amount of fine sand. Sand can lead towards better ravelling and skid resistance also improving the maximum compressive strength. On the other hand , too much sand and improper compaction energy may lead to an excessively low void content and reduced permeability. The present research aimed to analyze to the influence of fine sand addition (5%, 7% and 10 maximum) on the partial replacement of coarse aggregate into several properties of pervious concrete mixtures. The pervious concrete was obtained by the mixture of different size flyash aggregates (4.75mm, 9.5 mm,12.5 mm, 16 mm), portland cement, water with the little amount of sand. Admixtures super plasticizer is added to the mixture to enhance the strength of concrete. A trial being taken on preparation of flyash based pervious concrete 9FPC) with aggregate to cement ratio 1: 3, 1: 4 and 1: 6 with water to cement ratio 0.30, 0.35 and 0.40, respectively. Results suggested that adding small amounts of fine sand (around 5% of the total aggregate weight) in 1: 4 mix design of pervious concrete mixtures provided better mechanical and surface properties and a consequent reduction of drain ability, however, increase the percentage of and addition on pervious concrete leads to the decrease of water permeability rate. The correct balance of mechanical and hydrological properties can be achieved due to both accurate mix-design and proper compaction plan.

Subject: Removal of synthetic dyes from textile wastewter using microbes as bioadsorbents: A review
Keywords: Textile industries, Synthetic dye removal, Biosorbents, Microbial biomass, Biosorption, wastewater
Abstract: Over the past few decades, the use of synthetic dyes in textile industries has increased extensively. The effluent from textile industries is a principal source of dye pollution in aquatic ecosystems. Dyes discharged in aqueous streams deteriorate the water quality and exert potential health risks to human and aquatic living organisms. It is, therefore, exigent to remove synthetic dyes from the wastewater using cost-incentive and eco-friendly methods. A large number of physico-chemical processes have been applied globally for the scavenging of synthetic dyes from wastewater. This manuscript critically reviews various biosorbents, such as bacteria, fungi and algae as promising agents for dye removal from wastewater; discusses the mechanism of dye removal, impact of different physico-chemical factors on biosorption; analytical techniques and patented applications, etc.

Subject: Waste dump management at iron ore mines of Saranda forest region
Keywords: Mine, Waste dump, Reclamation
Abstract: The Saranda Forest region (West Singhbhum district, Jharkhand) is known to have huge deposits of superior grade iron and manganese ore. Mining of these minerals is bound to have adverse impacts on plants, wildlife and other ecosystems of the area. The present paper deals with a study of waste management practices adopted in iron and manganese ore mines of Saranda Forest region. Forestation, waste dump management, top soi management and management of subgrade minerals are some of the popular environmental restoration techniques practiced in all mechanized and semi-mechanized iron ore mines of the region. Mining and beneficiation of ores operations also cause environmental problems. The disposal of tailings and other deleterious siliceous and phosphorous materials from iron ore mines is a critical environmental threat. Therefore, to safeguard the environment and prevent ecological degradation, thrust needs to be paid on green belt development, solid waste management and other crucial environmental parameters. In this study various management techniques, such as retaining wall constrution, use of coir matting, garland drain to drain out surface water, biological reclamation, etc are also addressed in detail for stabilization of dump slope in Saranda Forest region.
