Desalinated water is expected to become the major source of drinking water in many places in the near future, and thus the major source of wastewater to arrive at wastewater treatment plants. The paper examines the effect of the alkalinity value with which the water is released from the desalination plant on the alkalinity value that would develop within the wastewater treatment process under v...

Water quality changes taking place during the infiltration process of treated wastewater produced by the Yeast Industrial Company, Jordan, are discussed. It was found that the COD, NH4 + and P04 ~"contents decreased with depth. More than 80% of NH4 + and about 95% of P04 3 and COD were removed at a depth of 70 cm in the soil profile. However, the electrical conductivity (EC) of the infiltrated ...

due to limitation of conventional water resources, the use of unconventional water for agriculture is unavoidable. therefore, in order to investigate the effect of using different amounts of municipal wastewater on yield, yield components and water use efficiency of cotton in drip irrigation systems, a field experiment was carried out during 2010 and 2011 growing season at experimental farm of ...

Global water scarcity is driving the need for identifying new water source. Wastewater could be a potential water resource if appropriate treatment technologies could be developed. One of the barriers to obtaining high quality water from wastewater arises from the presence of organic micropollutants, which are biologically active at trace levels. Removal of these compounds from wastewater by cu...

This paper examines potential uses of naturally growing aquatic plants for wastewater purification. These plants enhance the removal of pollutants by consuming part of them in the form of plant nutrients. This applies to urban and agricultural wastewater, in particular, where treatment units of different sizes can be applied at the pollution source. The effectiveness of wastewater purification ...

Evaluating and reducing various risks is a part of the corporations and organizations policies, any economic and non-economic entity must inevitably pay particular attention to the stage after the crisis in order to lead the organization's missions, carry out missions of the organization, and to reduce the costs and expenses of the various crises. A closer look can be said that the management s...

The application of membrane technology in water and wastewater treatment is increasing due to stringent water quality standards. Nanofiltration (NF) is one of the widely used membrane processes for water and wastewater treatment in addition to other applications such as desalination. NF has replaced reverse osmosis (RO) membranes in many applications due to lower energy consumption and higher f...

World Water Day is sponsored by the United Nations and observed each year on March 22. This year, World Water Day focuses on wastewater, which includes sewage, storm water, and discarded water used in the community (1). Many developing countries have inadequate wastewater management strategies because they lack resources, infrastructure, available technology, or space. Untreated wastewater in t...

Background: This study evaluated the quality of drinking water in rural areas of the city of Babol in terms of chemical parameters (iron, manganese, nitrite, and nitrate) and compared it with the Iranian and the World Health Organization (WHO) standards to determine the trend. Methods: This cross-sectional study monitored chemical test results for the years 2011-2014 of samples collected from ...
