Urban agriculture (UA) is practiced inside (intraurban) or on the outskirts (periurban) of a town or a city. While it focuses on raising food and animal crops, it includes recycling household waste and wastewater for agricultural purposes, the processing and distribution of different food and non-food products using human and material resources, products, and services that are found in the same...

because of water shortage in arid and semi-arid regions, reuse of wastewater and treated effluents for agricultural irrigation has become an essential matter now. while these kinds of water contain a lot of nutrients such as nitrogen, by using them we could be able to increase the soil fertility and decrease both the chemical nutrient consumption and the costs of agricultural production. howeve...

As competition among industrial, agricultural, urban and environmental sectors for freshwater intensifies, wastewater is frequently being seen as a valuable resource rather than mere waste. Furthermore, wise reuse of this water alleviates environmental concerns attendant with its discharge to coastal environments and inland waterways. Globally, around 20 million ha of land are irrigated with wa...

S WATER AND HEALTH – Vol. II-Helminth ova control in wastewater and sludge for agriculture reuse-B.

The seasonal occurrence of organic contaminants, many of which are potential endocrine disruptors, entering the Potomac River, USA, watershed was investigated using a two-pronged approach during the fall of 2005 and spring of 2006. Passive samplers (semipermeable membrane device and polar organic chemical integrative sampler [POCIS]) were deployed in tandem at sites above and below wastewater t...

Urban centers are unambiguously discharging wastewater in the natural streams, lakes, ponds and for irrigation in the agricultural fields. In the early stages of human civilization, wastewater discharges did not pose problem to water bodies as the nature had the capability for degradation and restoration of the quality of water to its normal condition.The key challenges towards better managemen...

Innovative wastewater treatment systems are needed for removing nutrients, noxious odors, dissolved organic matter, and pathogens from high strength agricultural and processing wastewater. A novel reciprocating subsurface-flow constructed wetland, consisting of four cells totaling 3570 m (1.5 m deep), has been treating anaerobic lagoon wastewater from a commercial-scale confined swine feeding o...
