Availability of irrigation water is a crucial problem especially in arid and semi arid regions; and hence, application of wastewater in agriculture in such regions seems to be an attractive preposition. Increasing need for water has resulted in the use of treated sewage water application for agriculture. In the present study, cotton (Gossypium hirsutum L.) crop was irrigated with treated sewage water (TSW) through phytorid sewage treatment plant (anaerobic and aerobic conditions) and well water (WW) completely randomized design. In both the treatments recommended NPK doses of fertilizers were applied. The results showed better crop growth throughout the growing period. Seed cotton yield was enhanced by 11.82% with treated sewage water irrigation over the irrigation by well water. The accumulation of heavy metal in plant was far below than the prescribed safe limit. Therefore findings give applicable advice to farmers and agricultural researchers for proper management and use of treated sewage water for crop irrigation.

The main objective of this study is to carry out to design of a sewage treatment plant for a Nagore and Nagore district, because it has been one of the developing pilgrimage places. Due to steady increase of increasing population, there will be more generation of domestic and municipal sewage. Sewage produces obnoxious smell which causes disease to all creatures. To avoid this problem, proper treatments is necessary before disposal to land by not throwing sewage directly to natural resources and reuse the treated water that ultimately reduces the overall demand of fresh water. Its objective is to produce an environmental safe fluid waste and solid waste suitable for disposal or reuse. In one day the total sewage generated was estimated 5 MLD considering the projected population of Nagore town for the next 30 years? Consequently this paper focuses on the sewage generation in the Nagore area based on the population and sewage treatment plant is designed accordingly. It is proposed to design the various components of sewage treatment plant considering the various standards and permissible limits of treated sewage water. The various components of sewage treatment plant are screening, grit chamber, primary sedimentation tank, biological reactor, secondary clarifier, activated sludge tank and drying beds.

Histopathological Results

Adult Nile tilapia, Oreochromis niloticus, of both sexes were exposed in wastewater from a sewage treatment plant for a period of 4 days. Gill samples were collected after 24, 48, 72 and 96 h and histopathological changes were analyzed by light and scanning electronic microscopy. Gill epithelium of control O. niloticus (freshwater group) was similar to that of other teleosts, while histopathological lesions were observed in exposed fishes. The main histopathological changes were edema, lifting of lamellar and filamentar epithelia and lamellar fusion. Cell proliferation with consequent thickening of the filament epithelium was also found in fishes exposed to the treated sewage water. The severity of the lesions increased with the time of exposure, namely the hyperplasia of the epithelial cells with proliferation of filamentar epithelium and fusion of lamellae observed at 96 h. Additionally, several histopathological results obtained by light microscopy were confirmed through scanning microscopy.

The plasmid contents of 306 strains of Escherichia coli isolated from raw and treated sewage from a treatment plant as well as from the water 1 km downstream were determined. The number and molecular weight of plasmids isolated from a representative sample of these strains were also measured. It was observed that biological treatment did not significantly alter these parameters. In contrast, statistically significant differences in plasmid number and size were observed when strains from sewage (raw and treated) were compared with strains isolated from brackish water. In raw and treated sewage, more than 96% of the strains contained plasmids, compared with 85% in brackish water. Nine to 13% of the strains from sewage contained plasmids with more than 56 kilobases, while only 5% of the strains from brackish water reached this size.Key words: Escherichia coli, plasmids, two-dimensional electrophoresis, sewage treatment, brackish water.

Abstract The article assesses the efficiency of pollutant removal at the sewage treatment plant in Goleniów after modernization of the technological system. The extension and modernization of the existing installation resulted from the need to adapt the treatment plant to accept larger loads of pollutants, improve the parameters of treated sewage discharged to the receiver, and the poor technical condition of the equipment. Before the modernization of the treatment plant, an increase in the loads of COD, BOD5, and periodic total suspended solids in raw sewage was observed as well as a reduction in the efficiency of removing pollutants from the sewage. The efficiency of removing pollutants after modernization was in the range of BOD5 - 94.4 ÷ 99.8%, COD - 89.3 ÷ 98.9%, total suspended solids TSS - 95.3 ÷ 99.7%, total nitrogen - 64.1 ÷ 95.4%, and total phosphorus - 75.4 ÷ 99.4%.

The rising population has not only increased the fresh water demand but also increased the volume of wastewater generated. Increasing need for water has resulted in the emergence of domestic wastewater application for agriculture and its relative use. In the present study a field experiment was conducted during 2012-13 and 2013-14 in which spinach (Spinacia oleracia) were irrigated with well water (WW) and domestic treated sewage water (DTSW). The use of the DTSW has shown improvement in the physicochemical properties of the soil, yield along with the nutrient status as compared to the application of WW. Post harvest pH of the soil in DTSW was in the range 7.85 whereas it was 7.93 in WW. EC and OC were found 0.43dS m-1 and 5.41 g kg-1 respectively in DTSW whereas it was 0.31 dS m-1 and 5.27 g kg-1 respectively in WW. NPK were found 279.6, 17.22 and 435.70 kg ha-1 respectively in DTSW whereas it was found, 266.8, 16.44 to 428.1 kg ha-1 respectively in WW. The physical properties of the soil like BD and HC observed 1.32 Mg m-3and 1.50 cm hr-1 respectively in DTSW and it was found 1.42 Mg m-3 and 1.54 cm hr-1 respectively in WW. The content of micronutrients and heavy metals in soil and plant due to irrigation of DTSW were well below the phytotoxicity limits in both soil and plant. The findings give applicable advice to commercial farmers and agricultural researchers for proper management and use of treated domestic wastewater for agricultural purpose.

Upflow Anaerobic Sludge Blanket (UASB) process is a popular process for treatment of sewage in India due to its low power requirement. However, UASB system has many limitations in terms of removal of carbon, nutrients and pathogens. This requires post treatment after UASB to meet the treated water quality standards. Current treatment processes adopted for the post-treatment of anaerobically treated sewage, especially the full-scale UASB reactors in Surat, India are presented. Two full scale treatment plants with different UASB post treatment processes viz., Extended Aeration and Moving Bed Biological Reactor (MBBR) are selected for studies. A pilot study was carried out in a full scale Sewage Treatment Plant (STP) to study the performance of Sequential Batch Reactor (SBR) for treatment of UASB treated sewage and the results are reported for period of Three months. Inlet and outlet parameters such as Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), etc. for post UASB biological process are presented. The performance of the SBR process was observed to be better among all the processes studied.
