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...

Due to the continuous release of antimicrobials into the environment, the aim of this study was to compare the frequency of detection of sulfamethazine, sulfamethoxypyridazine and trimethoprim in surface water collected from urban and rural areas in Northwestern Spain. A monitoring study was conducted with 314 river water samples analyzed by high-performance liquid chromatography coupled to tan...

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...

The benefits of Integrated Water Resources Management (IWRM) are widely known but its recommendations remain thinly implemented. Designing wastewater treatment plants for reuse in irrigation is a particularly underutilized IWRM opportunity that could potentially increase agricultural yields, conserve surface water, offset chemical fertilizer demand, and reduce the costs of wastewater treatment ...

When urban areas expand without concomitant increases in wastewater treatment capacity, vast quantities of wastewater are released to surface waters with little or no treatment. Downstream of many urban areas are large areas of irrigated croplands reliant on these same surface water sources. Case studies document the widespread use of untreated wastewater in irrigated agriculture, but due to th...

17 Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique 18 for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a 19 risk to water quality (especially if they are located relatively close to surface waters). In this 20 study, six STS in Sweden (11 to 28 years old) were examined. Samples taken from the 21 unsaturated subs...
