This paper deals with the study of bacteriological quality of effluents that have undergone consecutively different macrofiltration system (pressure sand filter or disc filter used as a secondary treatment) and UV254 irradiation process (used as a tertiary treatment). These two successive systems of treatment were evaluated to determine their possible application as commonly alternatives to the...

in the last twenty years, due to a number of natural and anthropogenic reasons, many water sources have become poorer in quality with respect to micropollutants. an example of a micropollutant that needs to be removed is the chlorophenoxypropionic herbicide mecoprop (mcpp). mcpp is one of the nine pesticides used as an indicator to monitor pesticide concentrations in rivers because it is freque...

In mining areas, groundwater resources are crucial for providing drinking water, as well water needed plant growth and mining. The Yuhengbei area is situated in arid semi-arid areas Western China. As there a number of large-scale fields the area, their exploitation may affect both quality quantity groundwater. hydraulic connection between aquifers directly determines whether deep coal activitie...

The high chlorine dosages in wastewater treatment plants during the COVID-19 pandemic may result increased formation of disinfection by-products (DBPs), posing great threat to aquatic ecosystem receiving water body and public health downstream area. However, limited information is available on effect biological processes CX3R-type DBPs. This study investigated oxidation ditch (OD) anaerobic-ano...

It has been well established that natural organic matters (NOMs) are precursors for the formation of disinfection by-products (DBPs) in drinking water supplies, thus removal NOMs is often used as an effective approach to limit DBPs production. In this study, we evaluated application oxidized multi-walled carbon nanotubes (OMWNTs)/polysulfone (PSU) nanocomposite hollow fiber membranes (HFM) and ...

Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...
