Water is prime requirement for surviving of any living beings.  The existence of surface water and groundwater sources are used for domestic, agriculture and industrial purposes in all over the world. Fresh water from both the water sources is highly contaminated in recent years because of rapid population growth, modern agriculture and industrial growth. Among them, contamination of water sour...

The paper reports the treatment performance capability, during an on-going full-scale study, which was set to evaluate the novel concept of integrated constructed wetlands (ICW) for domestic wastewater treatment in Ireland. The ICW at the center of this study is located at Glaslough in Co. Monaghan, Ireland. The 3.25 ha ICW comprises of two sludge cells and a sequence of five shallow vegetated ...

Settlement ponds are used to treat aquaculture discharge water by removing nutrients through physical (settling) and biological (microbial transformation) processes. Nutrient removal through settling has been quantified, however, the occurrence of, and potential for microbial nitrogen (N) removal is largely unknown in these systems. Therefore, isotope tracer techniques were used to measure pote...

Abstract Anthropogenic activities and climate change can deteriorate the freshwater quality stress its availability. This can, in turn, have an impact on biostability of drinking water. Up to now, microbiological water has been maintained through selection high-quality sources allied use disinfectants removal organic carbon. But as becomes richer other nutrients, strategies used so far may not ...

Parachlorophenol has an extended usage in refineries, petrochemical industries, insecticide, and herbicide manufacturing industries. Tire a solid waste, which is disposed in large amounts each year, a large number of them in landfills can cause irreparable environmental impacts. Consequently lots of efforts were done to produce activated carbon from used tires. Activated carbon was made in labo...
