water scarcity, its necessity in food production, and environmental protection in the world have forced human beings to seek new water sources. nowadays, application of unconventional water resources (wastewater) has been proposed in countries facing the crisis of water resources shortage; however, a few studies have dealt with this issue. the present study has evaluated the changes in the elem...

As the most important resource for life, water has been a central issue on international agenda several decades. Yet, world’s supply of clean freshwater is steadily decreasing due to extensive agricultural demand irrigated lands. Therefore, resources should be used with greater efficiency, and use non-traditional resources, such as Treated Wastewater (TW), increased. Reusing TW could an alterna...

The main objective of this work was to investigate on the possible conjunction of electrochemical processes (electrooxidation and electrocoagulation) for the treatment of dyes bearing wastewater for a possible valorisation in irrigation fields. The used methods were also tested separately to see the extent of the treatment yield of each technique. Experiments were conducted in laboratory confec...

Large amounts of untreated waste water of baker’s yeast industry from the Sudanese fermentation industry (SFI) are discharged in two different forms; molasses waste (MW) and wastewater from all processing operations. The objectives of the present study were to determine the chemical and physical properties of the wastewater from (SFI). Part of these characteristics is considered as parameters f...

the increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. using treated wastewater in agricultural irrigation can provide more adequate supply of high quality water for human consumption, but their heavy metal applications effect must be regulated to ensure no physiological problems for both the plant and ...

An area near the city of Chihuahua has been traditionally irrigated with wastewater to grow forage crops. It has been hypothesized that metal levels could be found in these soils high enough to cause potential health problems to the population. The objective of this study was to determine heavy metal concentrations in different soils due to irrigation practices. Four soil types were evaluated; ...

Nutrients and water found in domestic treated wastewater are valuable and can be reutilized in urban agriculture as a potential strategy to provide communities with access to fresh produce. In this paper, this proposition is examined by conducting a field study in the rapidly developing city of Hyderabad, India. Urban agriculture trade-offs in water use, energy use and GHG emissions, nutrient u...

The effects of plant species (castor bean (Ricinus communis L.) versus sunflower (Helianthus annus L.)) and irrigation regime (freshwater versus secondary treated municipal wastewater) on soil properties and on seed and biodiesel yield were studied in a three year pot trial. Plant species were irrigated at rates according to their water requirements with either freshwater or wastewater effluent...

The objective of this study is to compare the removal of Taenia eggs to the removal of Ascaris eggs in a wastewater stabilization pond system consisting of three ponds in series, where the hydraulic residence time distribution has been characterized via a tracer study supported by computational fluid dynamics modeling. Despite a theoretical hydraulic retention time of 30 days, the peak dye conc...

In and around urban areas pollution of natural water bodies is on the rise. As a result, wastewater irrigation is an increasingly common reality around most cities in the developing world. For reasons of technical capacity or economics, effective treatment may not be available for years to come; therefore, international guidelines to safeguard farmers and consumers must be practical and offer f...
