Abstract: Pollution caused by sewage discharged from cities and towns is the primary cause for degradation of our water resources. It is the obligatory responsibility of every local body to collect, transport, treat and dispose wastewater produced in their respective jurisdictions. Cyclic activated sludge process technology (c.Tech) is an advanced technology of sequential batch reactor (SBR) for treatment of sewage. It operates in a cycle of batches. Each cycle is of 3-5 hrs duration, during which all treatment steps take place. Two or more modules are provided to ensure continuous treatment of waste water. The complete process including removal of organics, N and Preduction takes place in a single reactor, within which all biological treatment steps take place sequentially. One cycle/sequence of operation consists of 3 steps-filling & aeration, settling and decantation. The settled sludge from the basin shows sludge volume index (SVI) <120 and excellent settling characteristics. The excess sludge wasted from the basin is fully digested and can be used as manure directly after dewatering. No additional settling unit, secondary clarifier is required. In Tamil Nadu, Madurai, corporation has constructed two STPs of C-Tech type with capacity of 125 MLD STP at Avaniapuram and 45.7 MLD at Sakkimanglam under Ju NURM scheme. These plants were commissioned in 2011. The report of analysis of treated sewage sample reveals that BOD is <9mg/L, COD<25mg/L and TSS is < 8 mg/L. The treated sewage is used for farming. By considering the performance of the existing plants in operation in India, it is concluded that cyclic activated sludge process is one of the best technologies which can be adopted by the local bodies.

Abstract: Soil and plant samples were collected from Pakkanadu carbonatite complex and were analyzed to understand the mobility of crtain trace elements (Ba, cr, co, cu, ni, pb, and zn). Biological concentration Factor (BCF), Translocation Factor (TF) and Biological Accumulation Coefficient (BAC) were calculated to understand the mobilization of trace elements into the plants of the study area. The trace element concentrations were analyzed in the common plants of the study area. The trace elements concentrations were analyzed in the common plants of the area viz ocimum sanctum, solanum nigrum, catharanthus roseus, curcuma longa and punica granatum. The maximum concentrations of trace elements (Ba, Co, Cu, Ni, and Zn) were observed in catharanthus roseus. The root of catharanthus roseus and curcuma longa had higher concentration of Ba. The results indicate the trace element concentrations in the plants of the study area exceed the permissible limit. The trace elements concentrations are authigenic and mainly accumualated in the roots of plant. Each plant species has different bioaccumulation capacity with respect to elements.

Abstract: The Municipality of Mettupalayam covering 7.2 square kms, and with vast regular and floating population, is a prime factor for waste generation and management. Targeted under public private partnership, waste management is undertaken by the collective effort of the municipality with the private body IWMUST. In the current study various sites were selected in Mettupalayam Municipality for solid waste sampling. The waste samples were collected from five different locations during its different stages of waste management, i.e. primary collection, secondary collection, temporary storage at disposal site, treatment and final disposal. The municipal solid waste samples tested for the physico-chemical characteristics, showed high level of impact on physical and chemical environment. Climatic conditions were found to drastically affect physico chemical characteristics as well as volume of Total solids, Ash content, volatile content and organic Residue. Harmful biomedical waste and improper safety measures caused serious health hazard to sanitary workers.

Keywords: Polyvinyl alcohol; Chemical Oxygen demand; total organic carbon; total carbon.
Abstract: PVA (Polyvinyl alcohol) is completely degraded and utilized by non-ubiquitous microorganisms as a sole source of carbon. PVA containing effluent treatments are not preffered because of high cost. PVA causes serious environmental pollution hence the objective of this work was to establish rapid and reliable method for analysis of COD (chemical oxygen demand) and PVA concentration in textile desizinge or any PVA containing effluent. Two indirect methods namely COD by TC (Total Carbon) and TOC (Total organic Carbon) were compared with COD by TC and TOC whereas for 1-4% PVA it was <10 for COD by TC and 30 to 35 for COD by TOC. Standard deviation range for indirect COD by TC was 600-3000, while indirect COD by TOC for PVA containing samples and more rapid than COD chemical. The spectrophotometrically analyzing PVA concentration by iodine method was reconfirmed and absorbance at 690 nm indicates corresponding PVA concentration. TC and iodine methods of analyzing PVA containing effluent were rapid and precise than conventional chemical COD method; these could be useful in the faster pollution detection and environmental protection from PVA.

Keywords: Geophysical techniques, Electrical resistivity, Apparent Resistivity.
Abstract: Electrical resistivity methods have been widely used to study ground water contamination. The decrease in resistivity caused by salinization of ground water helps to identify the contaminant zones. Resistivity sounding determines the thickness and resistivity of different horizontal or low dipping subsurface layers including the aquifer zone. Surface geophysical surveys provide an effective way to image the subsurface and the ground water zone without a large number of observation wells. Resistivity sounding generally identifies the subsurface formations, the aquifer zone as well as the formations saturated with saline/brackish water. The protection of ground water resources from pollution has been a high priority topic in recent years. The paradox of the modern society is that some of our efforts towards economic prosperity and increased standard of living could be detrimental to the overall quality of life due to encroachment upon the nature beyond its sustenance level or rejection of pollutants to environment exceeding its assimilative capabilities. With the increasing concern for groundwater protection, problem of predicting the movement by pollutants has gained greater attention. This project aims to detect Ground water pollution of municipal solid waste dumpsite of Perungudi Dumping Yard at Chennai. The study area is bounded by Pallikaranai Marsh land in the West and Buckingham canal in the east. In the recent years, Geophysical technique applications are used for Ground water exploration. The Schlumberger configuration was used to create one dimensional apparent resistivity model. The apparent resistivity ranges from 0.2 ohm-m to 317 ohm-m. The low apparent resistivity indicated that the ground water has been contaminated by leachate. The maximum impact of dump yard was observed up to approximately. 1.5 km through resistivity method.

Abstract: Coal is a major source of energy and its consumption is increasing day by day. When coal is burnt in thermal power plants, Fly ash is produced as a bye product. Flu ash is thus industrial waste generated from thermal power plants. It constitutes 80-85 percent of the total ash produced in the power plant. For fly ash disposal about 35,000 hectare of land is required in India. One of the main problems in disposing of big quantities of fly ash is the possible leaching of different pollutants, including fluoride. A thorough investigation regarding leaching of fluoride from fly ashes is much essential to know the impact of fluoride due its leaching from fly ash to ground water as well as surface water. In the present study leaching studies have been carried out on fly ash, bottom ash, pond ash and weathered ash of Amarkantak thermal power station (ATPS) Chachai and Sanjay Gandhi thermal power station (STPS) Birsinghpur district Shahdol Madhya Pradesh, India. The amount of Fluoride released in different experiment has been evaluated. The different samples of ashes have been collected and analyzed for some physico chemical parameters and fluoride content.

Keywords: Distillery waste water, Anaerobic sequencing batch reactor, Hydraulic retention time, organic loading rate, substrate degradation rate.
Abstract: Distilleries are one of the most polluting industries generating large volumes of carbohydrate rich wastewater. Studies were made to investigate the potential of bio-hydrogen production and bio-methane production from distillery wastewater using two phase system comprising of two separate anaerobic sequencing batch reactors in series. The active volume of both the reactors was 3.5 L pretreated anaerobic distillery sludge and anaerobic distillery sludge were used as seed in hydrogen reactor and methane reactor respectively. Bio-hydrogen production was studied by dark fermentation process at ambient temperature and operating pH of 6.0? 0.2. The hydrogen reactor was sequenced three times a day providing a cycle length of 8h and the methane reactor was sequence once a day with a cycle length of 24h. Each cycle operation consisted of four stages: feed, react, settle, and decant. The organic loading rate was increased by decreasing the hydraulic retention time from 96h to 72h, 48h, 36h and 24h. Gas production trend and cumulative gas production were studied at various hydraulic retention times. Maximum gas production was observed at 36h HRT in the hydrogen reactor and 24h HRT in the methane reactor. Experimental data recorded a maximum volumetric gas production rate of 1.286m?/m?/d at 48h HRT in the hydrogen reactor and 0.577m?/m?/d at 96h HRT in the Methane reactor. Maximum specific gas production was observed to be 0.07976m?/kgcod removed in the hydrogen reactor and 0.02967m?/kgcodremoved in the methane reactor. Substrate degradation rate was found to vary from 8.89kg cod /m? /d in the hydrogen reactor and from 4.8625kgcod/m?/d at OLR of 14.1 kgcod/m?/d to 21.4kgcod/m?/d at OLR of 81.9kgcod/m?/d in the methane reactor. Experimental data showed the feasibility of bio-hydrogen and bio-methane production with substrate degradation using distillery wastewater as substrate.

Keywords: Self compacting concrete, Fly ash, Super plasticizer, Viscosity modifying, agent, Compressive strength, Split tensile strength, Flexural strength.
Abstract: Fly ash is one of the residues generated in combustion and comprises the fine particles that rise with the flue gases. In the past, fly ash produced from coal combustion was simply entrained in flue gases and dispersed into the atmosphere. This created environmental and health concerns that prompted laws which have reduced fly ash emissions to less than 1% of ash produced. The use of fly ash as concrete admixture not only extends technical advantages to the properties of concrete but also contributes to the environmental pollution control. In India alone, we produce about 75 million tons of fly ash per year, the disposal of which has become a serious environmental problem. Therefore, the effective utilization of fly ash in making concrete is attracting serious considerations of field engineers. This paper outlines the study of materials, methods; mix proportion, workability tests and mechanical properties of Self Compacting Concrete (SCC). SCC is a special type of concrete having more powder content containing cement, fly ash, aggregates apart from chemical admixtures. Super plasticizer and viscosity Modifying Agent (VMA) are used to impart filling ability, passing ability and resistance to segregation. In this system, the coarse aggregate and fine aggregate contents are fixed and self-compatibility is to be achieved by adjusting the water/powder ratio and super plasticizer dosage. The cube compressive strength, cylinder compressive strength, split tensile strength, Flexural strength were determined adopting conventional testing procedure. The present study indicates that self compacting concrete can be produced with the above mentioned waste material of thermal power plant and this concrete will be helpful to place the concrete it congested reinforcement area.

Abstract: Cement industry is flourishing in Satna district due to rapid population growth, the change in living style, and the availability of raw material in the region. Unless restricted regulations are enforced by local authorities to ensure compliance with national and international standards upon this industry, the increase of cement factories and their associated quarries in the region may deteriorate air quality and thus threaten the fragile ecosystems in the region. This paper presents predictions of air pollutants (PM10, PM2.5, SOx AND NOx) emitted from Birla Vikas cement plant, Satna (M.P). The proposed study indicates that concentration of gaseous pollutants was found well within the permissible limit but particulate matter especially PM10 was found slightly high from the permissible limits. Therefore, the proposed activity may pose adverse impact on the environment of the study area.

Abstract: The experiment in the paper are mainly of hypertrophy of gills was that induced in the fish, Glossogobius giuris by the administration of ?Azadirachtin? a component of neem oil. The efficacy of Azadirachtin and nulagi combination was evaluated. Interestingly, the combination of Azadirachtin and nulagi drug has effect on normalization of hypertrophy of gills. Though the Azadirachtin brought changes like lifting of gill lamellae, fusion of secondary lamellae and edema condition is very much evident along with Hyperplasia, hyperemia and hypertrophy of secondary lamellar epithelial cells in the gills of Fish, Glossogobius giuris. Diatoms are major group of algae which are the most common type of phytoplankton. The introduction of Nulagi, the micronutrient, at various intervals at different concentrations brings varying responses to gill architecture, further the investigation reveals that the nulagi can produce enormous oxygen by photosynthetic activity and thereby control water pollution by absorbing the carbon dioxide. Fish and shell fish are economically important food sources and their survivality may increase due to good oxygen levels and less Eutrophication situation. The work on Gills, in the present context is more relevant since it is vulnerable to water soluble toxicants or micro organisms.

Abstract: Spaceborne sensors allow for wide-scale assessments of forest ecosystems. Combining the products of multiple sensors is hypothesized to improve the estimation of forest biomass. We applied interferometric (Tandem-X) and photogrammetric (WorldView-2) based predictors, e.g. canopy height models, in combination with hyperspectral predictors (EO1-Hyperion) by using 4 different machine learning algorithms for biomass estimation in temperate forest stands near Karlruhe, Germany. An iterative model selection procedure was used to identify the optimal combination of predictors. The most accurate model (Random Forest) reached a r2 of 0.73 with a RMSE of 14. 9 % (29.4 t/ha). Further results revealed that the predictive accuracy depended highly on the statistical model and the area size of the field samples. We conclude that a fusion of canopy height and spectral information allows for accurate estimations of forest biomass from space.
