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.

The Past

The Standards controlling sewage treatment are continuously in development. Thus, upgrading existing plants is a frequently encountered problem. In the past this meant structural changes, mostly in terms of enlargement of existing facilities or addition of new units. More recently the possibilities of improving plant performance through chemicals addition (inducing precipitation and coagulation) with or without intensified biological treatment have been explored. Chemicals addition has become necessary in many instances due to the tightening of standards for phosphorous concentrations in the plant effluent. The present discussion is based on a case study where possibilities and limits of chemical and/or biological upgrading have been investigated. The analysis showed that neither chemical stages nor secondary biological stages alone can guarantee the effluent standards formulated by the water authorities.

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.

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.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

Municipal Sewage Treatment Plant

In this investigation it was found that the waste sludge obtained from a municipal sewage treatment plant could be reclaimed as an adsorbent for removal of organic vapours, i.e. toluene, methyl-ethyl-ketone and 1-1-2-trichloroethylene, through use of a pyrolysis technique. In order to find the optimum manufacturing process, several tests were performed under various conditions in which the addition of a catalyst, temperature control, and residence time in the furnace, were considered as the three major factors. Both the reclaimed adsorbent and commercially available activated carbon were evaluated to determine their adsorption capacity at various influent concentrations of organic vapours.
