Abstract This research emphasized the importance of removing organic pollutants from wastewater discharges. In this review, different advanced oxidation processes are discussed. A broad classification was used for treatment. An overview TiO2-based photocatalysis, Fenton process, and photocatalytic ozonation has been done. The mechanism methods studied. advantages limitations these also Various ...

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

background: a new biological domestic wastewater treatment process, which has been presented these days in activated sludge modification, is upflow sludge blanket filtration (usbf). this process is aerobic and acts by using a sludge blanket in the separator of sedimentation tank. all biological flocs and suspended solids, which are presented in the aeration basin, pas through this blanket. the ...

Textile industries significantly impact the contamination of wastewater. Conventional wastewater treatment methods consider most common pollutants; however, they are very expensive and commonly produce toxic by-products. In scientific community, advanced oxidation processes appear to be appealing, a majority published work considers heterogeneous photocatalysis for degradation various chemicals...

Photocatalytic experiments on the pharmaceutical pollutant carbamazepine (CBZ) were conducted using sol-gel nitrogen-doped TiO2-coated glass slides under a solar simulator. CBZ was stable to photodegradation under direct solar irradiation. No CBZ sorption to the catalyst surface was observed, as further confirmed by surface characterization using X-ray photoelectron spectroscopic analysis of do...

Energy crisis and environmental pollution are the major problems of human survival development. Photocatalytic technology can effectively use solar energy is prospective to solve above-mentioned problems. Carbon nitride a two-dimensional polymer material with graphite-like structure. It has good physical chemical stabilities, unique electronic band structures, widely used in field photocatalysi...

TiO2 nanorod arrays (TiO2 NRAs) sensitized with CdS nanoparticles were fabricated via successive ion layer adsorption and reaction (SILAR), and TiO2 NRAs were obtained by oxidizing Ti NRAs obtained through oblique angle deposition. The TiO2 NRAs decorated with CdS nanoparticles exhibited excellent photoelectrochemical and photocatalytic properties under visible light, and the one decorated with...

Background : Effluents containing synthetic dyes are hazardous to ecological systems and public health. Methylene blue is an important chemical aromatic dye which commonly used in textile industries. Due to being aromatic, it is often toxic, carcinogenic and mutagenic. The goal of this study was to investigate the efficiency of ZnO nano particles photocatalytic process for decolorization of met...
