CHECK THESE SAMPLES OF The nature and extent of environmental health concerns surrounding the use of sludge and biosolids from wastewater treatment in agriculture
...Series No. 517, World Health Organization, Geneva. According to this document; 3.4 Disposal Methods Wastewater treatment yields sludge as the major bi-product. The amounts of this entirely depend on the level of purification of the wastewater. In other words, the more the sludge the better the wastewater as regards its quality. With these large quantities of sludge, it is emerging that improper disposal procedures like landfills are posing a great danger especially to agriculture production, and also that it may recontaminate water masses. 4.0 Various strategies that will improve the...

...and process. The sludge that results from the CEPT technique is about 10 to 15% higher than that resulting from removal of suspended solids. Last, CEPT is an appropriate and effective first stage treatment process, and biological treatment may follow based on justification and affordability. Conclusion The main water-related environmental concern eminent in urban areas of most developing countries is public health. Receiving water and drinking water sources are often contaminated inadequately treated wastewater effluents. Despite the presence of conventional primary treatment, disinfection of effluent is...

...treatment with supplemental carbon. Anaerobic and anoxic zones also provide better control of foaming if backmixing is eliminated and the recycle of NOx and DO to the zones is minimized. Further, good removal of nitrogen reduces concern over denitrification and floating sludge in the secondary clarifiers, and provides the option of over-sizing the clarifiers to better handle wet weather flows. Also, nutrient recovery and reuse is gaining national and international attention as a key aspect in sludge management plans. Rather than being disposed as a “waste,” sludge is now being harvested for valuable resources and used as an alternative...

...The appropriate use of reclaimed water includes letting the public know about it. According to the American Water Works Association (2009), “…the public [should be made] aware of reclaimed-water use” (pp. 67). Reclaimed water systems should definitely be cleaned out periodically as well, in order to facilitate health standards—and to ensure water quality. According to Asano (2007), “It is good practice to flush the reclaimed water distribution network periodically because reclaimed water systems [have biofilm build-ups versus] potable water systems. Flushed reclaimed water can be discharged to the wastewater collection system, or with appropriate waste discharge...

...in wastewater treatment plants that use a great deal of energy in their processing, further damaging the environment.1 Surfactants become a part of the environment when they are discharged into the soil and bodies of water through treated wastewater. In order to understand the effect of the surfactants on the ecosystem, it is necessary to understand their behaviors. Sorption of a surfactant is dependent on a variety of factors, including the physiochemical properties, parameters within the environment, and the nature of the sediment and soil. Surfactants undergo sorption in soil, sludge, and sediment in a specific order:...

...Environmental Concerns: Global Warming Environmental Concerns: Global Warming Introduction Global warming also known as greenhouse effect has beenone of the most serious environmental concerns of the past few years. According to many recent surveys, global warming has been selected as one of the top environmental concerns by the public (The World’s Water 2008-09, 2010). The main greenhouse gases are water vapour, CO2, methane, nitrous oxide, ozone and halocarbons (IPCC, 2007a). The main contributor (4 to 36 percent) of greenhouse gas effect is CO2 which is mainly caused by manmade activities like...

...process found in the primary stage. The processes in the tertiary stage are more advanced compared to those in the secondary stage because human consumption is inevitable for reclaimed water from the tertiary stage unlike that from the secondary stage. Humans can easily contract diseases from contaminated water thus the precautions taken must be great. Therefore water from the tertiary stage is fit for drinking.

..., the concern is largely the number of medical cases that are rising. Medical conditions and other diseases that were alien to the American society are now here with us. Every day there is a recorded increase of new diseases and the number continue to increase. In Colorado, for example, obesity, which is an enormous health concern, continues to escalate. In estimation, the percentage of those considered being obese is 20 percent. In Mississippi, the percentage is unusually high, going up to 34.9 percent. Nationally, the adult population considered being obese is 27.8 percent, which is a growing number. This revelation brings us to the conclusion that one...
