background: hospitals generate relatively large quantities of wastewater that may contain various potentially hazardous ma­terials; therefore the proper management of hospital wastewater is essential. methods:   in this cross-sectional study, the quality and quantity of wastewater in the hospitals of tehran university of medi­cal sciences (tums), tehran, iran, were studied and the suitable meth...

A one-dimensional (1D) nanostructure having a porous network is an exceptional photocatalytic material to generate hydrogen (H2) and decontaminate wastewater using solar energy. In this report, we synthesized nanoporous 1D microrods of graphitic carbon nitride (g-C3N4) via a facile and template-free chemical approach at room temperature. The use of concentrated acids induced etching and lift-of...

One of the biggest problems world is currently experiencing wastewater treatment. Numerous pollutants are released into water bodies by enormous amounts effluents from varied sources. This paper provides a concise summary state art in AOPs, biological treatment, and their efficient application for degradation numerous recalcitrant organic contaminants found wastewater. The employment photoreact...

This review compiles recent advances and challenges on photocatalytic treatment of wastewater using nanoparticles, nanocomposites, polymer nanocomposites as photocatalyst. The provides an overview the fundamental principles along treatment, especially modification strategies operational conditions to enhance efficiency removal recalcitrant organic contaminants. different types photocatalysts ke...

<p>Photocatalytic degradation for wastewater treatment is a method that has recently attracted attention. In this research, synthesized composite of Fe3O4/SiO2/NiO with magnetic properties was used the photocatalytic methylene blue dye under UV light. Furthermore, composites were characterized using XRD, FTIR, BET surface area, SEM-EDS, VSM, and UV-DRS. The results showed saturation magne...

phenols are toxic organic compounds and which badly affects the flora and fauna of thebiosphere because phenols are persistent pollutant found in wastewater from many industries. in presentresearch article the photocatalytic removal of o-nitro phenol by synthesized magnetic nanoadsorbents(mna) carried out under photocatalytic reactor. the mna were synthesized by co-precipitation methodrequired ...

The research in this Thesis has been mainly performed at the research group Trataguas, from the Departamento de Ingeniería Química y Química Física of the Universidad de Extremadura. It is a part of an extensive research program on the elimination of emerging contaminants (ECs) in water through the application of advanced oxidation processes (AOPs), being developed by the Trataguas group and fi...

to study the feasibility of anaerobic filter in raw sewage and slaughter house wastewater treatment, slaughter house wastewater treatment, a batch flow pilot plant was designed. in phase one, with a detention time of 3-days and no mixing, the maximum reduction in cod was 23%. in the second phase, with a detention time of 2-days and complete mixing, glucose was added to the raw sewage, the reduc...

Water used by mining enterprises needs to be comprehensively recovered and utilized achieve clean production. This requires the effective treatment of mineral processing wastewater. Wastewater produced during non-ferrous metal contains a complex mixture pollutants at high concentrations, making comprehensive difficult. Here, sources hazards posed wastewater are introduced techniques for removin...

introduction: humic acid (ha) is one the original disinfection byproducts processors in water treatment. so, removing it is necessary before water chlorination. in the present study, photodegredation of humic acid in water using ag/zno nano particle under uvc irradiation in batch system was investigated. material and methods: photocatalytic study was carried out to evaluate the effect of uvc (1...
