Adsorption of poliovirus from primary sewage effluent was similar to that from secondary sewage effluent in both batch soil studies and experiments with soil columns 240 cm long. Virus desorption by distilled water was also similar in a soil column that had been flooded with either primary or secondary effluent seeded with virus. These results indicated that absorption of poliovirus from primar...

Climate change makes people to be aware about the environmental pollutions in aspect of Air, Water and Soil components. The environmentally aware countries have forced the other countries to implement the stringent effluent standards for disposal into water stream / water bodies. Hence, modern technology like the application of membrane separation (Micro or Ultra filtration) technique with biol...

The choice of management practices for the treatment of piggery effluent prior to its disposal to waterways or land is governed by the desire to simultaneously minimise the cost of treatment whilst minimising pollution of the environment. Laboratory experiments were conducted to compare the removal of total and total filterable phosphorus (P) (<0.45 microm) from ortho-phosphate solutions or pig...

Micro flora of the effluents from a dairy factory in Tehran(Pegah Dairy Processing Plant) were isolated and screened for their ability to reduce the organic matter content and COD of the effluents. 10 bacteria were selected due to  reduction in COD content from the 4th to 6th day of incubation at 30 °C and  pH =11. Highest COD reduction were obtained by two isolates, BP3...

Fish were collected from Nath Sagar, Paithan 50 kms away from Aurangabad and were brought to the laboratory and exposed to industrial effluent (tannery effluent). Behavioral changes and responses of the fish to the tannery effluent were observed. Control fish showed normal behaviour and swimming in contrast the effluent exposed fish showed abnormal swimming, loss of equilibrium, fading of colou...

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...

In the present study effect of fertilizer factory effluent on seed germination, seedling growth and chlorophyll content of gram (Cicer aeritenum) has been carried out, at different concentration of the effluent and time intervals. The effluent is alkaline in nature with strong ammonia odour. The germination percentage of seed, seedling growth and chlorophyll content showed a gradual decline wit...

C. 2. c. EFFLUENT VERSUS ABSORPTION AREA WATER QUALITY DURING THE RESEARCH STUDY Hydrogen ion concentrations (pH), EC values, and chloride ion concentrations remained consistent between effluent and subsystems samples each year. Effluent nitrate-N concentrations were lower and ammonium-N concentrations higher than those concentrations found within either subsystem in the absorption area. This w...

Worldwide, wild fish living in rivers receiving municipal and industrial discharges may experience endocrine disruption as a result of exposure to anthropogenic pollutants. The purpose of this study was to evaluate the hormonal status of wild fish in a U.S. river receiving unbleached kraft and recycled pulp mill effluent (Pearl River at Bogalusa, LA). We evaluated two alternative hypotheses: th...

Commercial nuclear power plants release gaseous and liquid radiological effluents into the environment as a byproduct of electrical generation. These releases are monitored by federal agencies to ensure compliance of regulatory limits. The U.S. Nuclear Regulatory Commission (NRC) and U.S. Environmental Protection Agency (EPA) offer guidance and make recommendations for domestic power plants eff...
