The disposal and treatment of wastes generated in the leather industry has been the focus of several studies around the world. They intend to meet environmental legislation and make the process environmentally and economically viable. The anaerobic digestion process, which occurs in steps that involve acid and methane forming bacteria, can be an alternative since it turns the waste into renewab...

The wastewater quality index (WWQI) is one of the most significant methods presenting meaningful values that reflect a fundamental characteristic wastewater. Therefore, this study was performed to develop prediction approach using WWQI for regional treatment plant (WWTP) in Melaka, Malaysia. system WWTP provides huge amount registered data due many parameters recorded daily. A multivariate stat...

The environmental sustainability of a semi-industrial solar photo-Fenton reactor, treating real effluents emanating from a pharmaceutical laboratory, is assessed herein. The life cycle assessment/analysis (LCA) methodology was employed and real life cycle inventory (LCI) data was collected from a ferrioxalate-assisted homogeneous solar photo-Fenton wastewater treatment plant (WWTP), at Ciudad R...

In this study, performance estimation of biological wastewater treatment plants (WWTP) was made by applying Artificial Neural Network (ANN) techniques. As material, 355-day data from Adana Metropolitan Municipality Seyhan plant for 2021 were used. Of the used, 240 evaluated as training and 115 test data. establishment ANN model, daily chemical oxygen demand (COD), water flow (Qw) suspended soli...

Ever-tightening regulations on releases to the environment have become a major business factor for the chemical industry. The Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) effluent guidelines have required many manufacturing sites to expand or upgrade their wastewater treatment plants ("P) at considerable cost. Du Pont has recognized the need to shift the emphasis from "end-of-pipe'...

Antibiotic resistance represents a global health problem, requiring better understanding of the ecology of antibiotic resistance genes (ARGs), their selection and their spread in the environment. Antibiotics are constantly released to the environment through wastewater treatment plant (WWTP) effluents. We investigated, therefore, the effect of these discharges on the prevalence of ARGs and bact...

Total nitrogen (TN) and total phosphorus (TP) concentrations are important parameters to assess the quality of water bodies and are used as criteria to regulate the water quality of the effluent from a wastewater treatment plant (WWTP) in Korea. Therefore, continuous monitoring of TN and TP using in situ instruments is conducted nationwide in Korea. However, most in situ instruments in the mark...

Within the framework of a one-year study the treatment capacity of a municipal wastewater treatment plant (WWTP) was evaluated, with regard to fecal indicator bacteria (FIB) and to their influence on the recipient. The logarithmic reduction rates for fecal coliforms (FC), Escherichia coli (EC) and intestinal enterococci (IE) were 2.84, 2.90 and 2.93. In the investigated period of time, the test...

The streams from municipal wastewater treatment plants (WWTP) have been considered a valuable medium for mass cultivation of algal biomass. The aim of this work is to test and compare the performance of Chlorella vulgaris on several streams from five stages, from two different WWTP. The results showed biomass yields ranging from 39 to 195mg dry-weightl(-1)days(-1). The best performance as bioma...

Horizontal gene transfer is a major contributor to the evolution of bacterial genomes and can facilitate the dissemination of antibiotic resistance genes between environmental reservoirs and potential pathogens. Wastewater treatment plants (WWTPs) are believed to play a central role in the dissemination of antibiotic resistance genes. However, the contribution of the dominant members of the WWT...
