nowadays, application of unconventional water such as wastewater is one of the strategies for preventing water deficit. this study was conducted to evaluate effect(s) of treated wastewater application on microbial and chemical contamination of soil and wheat (chamran v.). five treatments included t1 (irrigation with 100% fresh water), t2 (75% fresh water + 25% wastewater), t3 (50% fresh water +...

Population and urban growth is one of the major challenges facing Africa. Rapid urbanization poses major infrastructure, economic, environmental and social problems. Total water supply and sanitation coverage is extremely low particularly in sub-Saharan Africa (SSA) and cities are becoming to a large extent informal. Untreated urban wastewater is polluting water sources throughout SSA changing ...

The growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. Various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (MD) process, as a promising separation technology, has recently gained more attention. The MD process is a non-isothermal membrane-based separati...

water resource constraints on the one side, the industrial and urban infrastructures which cannot cope with the growing demand, and the need for adequate planning on the other hand, emphasizes the importance of using a comprehensive and systematic approach in the field of water resources management and infrastructure development more obvious and significant day by day. also, exposure to large a...

groundwater is the main source of potable water in most areas of mazandaran province, like sari and babol city. thus the safety of groundwater supplies is very important in these regions. unfortunately attention to groundwater quality has remained limited in iran. in recent years, the growth of industry, technology, population, and water use has increased the stress upon both land and water res...

Given the current demographic trends and future growth projections, as much as 60% of the global population may suffer water scarcity by the year 2025 [9]. In addition to water scarcity, water quality deterioration is expected to intensify in resourcepoor countries in dry areas, due to human activity and climate change. It is projected that water scarce countries will have to increasingly rely ...

Cyanobacterial blooms often occur in aquaculture wastewater in China. A floating plant, water hyacinth has been widely used to treat this wastewater. Little is known, however, about bacterial community characteristics and the risk of potential pathogens in cyanobacteria-blooming aquaculture wastewater remediated by water hyacinth. In wastewater treated with water hyacinth, we used culture enume...
