background sewage sludge (biosolids) is a byproduct of wastewater treatment that accumulates in large quantities. effective stabilization and disinfection of sewage sludge prior to land application are necessary to not only protect human health, but also to induce the public its benefits and safety. currently, many wastewater treatment plants in iran dispose great amounts of untreated sewage sl...

this research, in addition to survey the existing data on the quality of sahebgharanieh wastewater treatment plant's effluent in the previous years, by runing a three months monitoring stage, studies the conditions of the final settling and aeration basin and the variations of the influent and effluent quantity and quality in removing of major pollutants (bod, cod, tss), while scrutinizing the ...

Rapid contamination of drinking water in distribution and storage systems can occur due to pressure drop, backflow, cross-connections, accidents, and bio-terrorism. Small volumes of a concentrated contaminant (e.g., wastewater) can contaminate large volumes of water in a very short time with potentially severe negative health impacts. The technical limitations of conventional, cultivation-based...

The production of beer is characterized by the consumption of large volumes of fresh water. Whereas, cleaning operations are the highest water consumption demanding activities in breweries. Commonly “Cleaning In Place” (CIP) systems are used in closed processing lines. These consist of automatic cleaning and disinfection programs based on a succession of several solutions of water, cleaning che...

Antimicrobial resistance (AMR) is a serious problem for modern society, not only associated with clinical environments, but also the natural environment. Conventional wastewater treatment plants (WWTPs) are important nodes dissemination of antibiotic to aquatic environment since they reservoirs antibiotic-resistant bacteria (ARB), genes (ARGs), and residues. WWTPs designed remove these determin...

Combined with human-to-human contact, the potential for SARS-CoV-2 virus transmission via aerosols and feces raises urgency effective treatment of hospital wastewater (HWW), which has been assumed as an important source pathogenic microorganisms spreading into aquatic environments. However, there are few reviews discussing presence removal pathogens in wastewaters matrices. This review summariz...

Ferrate(VI) is a green and efficient water treatment agent for drinking wastewater. It widely used in because it has multi-functional uses such as oxidation, algae removal, disinfection, adsorption flocculation. does not cause secondary pollution to the environment. This paper compares ferrate(VI) with other agents discusses three methods of preparing ferrate(VI). The adsorption, control organi...

This work focuses, for the first time, on mechanistic modelling of wastewater disinfection by solar photo-Fenton process using controlled simulated radiation. At circumneutral pH, iron precipitates forming hydroxides and significantly affecting optical properties water. In this regard, radiation transfer in reactor has been taken into account. The proposed model considers that inactivation bact...
