In contrast to biological treatment systems, the mechanical treatment of wastewater represents a fast to implement and cost-effective solution for the removal of undissolved matter from wastewater flows. New developments in the field of mechanical wastewater treatment can be tailored to meet specific cleaning targets and requirements situations. Especially the combination of very fine apertures...

Aerobic treatment of bagasse pulp wastewater could be greatly improved by flocculantproducing and lignin-adsorbing bacterial sludges. The fine fibrous particles and lignln contained in the wastewater could be removed by the respective microbial sludge. They could replace the chemicals used for the secondary treatment. Continuous treatment of the wastewater by the sludges was conducted for two w...

The paper provides a critical comparison between mesophilic and thermophilic anaerobic treatment of PTA wastewater through diagnosis of a case study. Aspects covered are bioavailability, biodegradability, microbial population, thermodynamics, kinetics involved and bioreactor design for PTA wastewater treatment. The results of the case study suggests that onestage thermophilic anaerobic reactor ...

This study aims to assess the removal efficiency of microbial contaminants in a local wastewater treatment plant over the duration of one year, and to assess the microbial risk associated with reusing treated wastewater in agricultural irrigation. The treatment process achieved 3.5 logs removal of heterotrophic bacteria and up to 3.5 logs removal of fecal coliforms. The final chlorinated efflue...

Tannery wastewater contains large quantities of organic and inorganic compounds, including toxic substances such as sulfides and chromium salts. The evaluation of wastewater quality in Chile nowadays is based on chemical specific measurements and toxicity tests. The goal of this research was to characterize tannery wastewater and to relate its physical/chemical parameters with its acute toxicit...

background: water resource management is a strategic issue in qom city. water scarcity is one of the most critical concerns of industrial estates. this study aimed to evaluate wastewater management in the shokuhieh industrial park of qom province in 2013. methods: this is a descriptive cross-sectional study done by visiting the industrial units in person, completing questionnaires and analyzing...

The occurrence and spread of multi-drug resistant bacteria is a pressing public health problem. The emergence of bacterial resistance to antibiotics is common in areas where antibiotics are heavily used, and antibiotic-resistant bacteria also increasingly occur in aquatic environments. The purpose of the present study was to evaluate the impact of the wastewater treatment process on the prevale...

The potential of effluent DOM to undergo microbial degradation was assessed in batch experiments. Effluent samples from Haifa wastewater treatment plant and Qishon reservoir (Greater Haifa wastewater reclamation complex, Israel) were incubated either with effluent or soil microorganisms for a period of 2-4 months and were characterized by dissolved organic carbon contents (DOC), UV(254) absorba...

the ultimate goal of this work was to recommend and install the necessary advanced wastewater treatment facilities to allow southern service company to continue discharging wastewater into st. bernard sewerage district no. 1 sanitary sewer system. as of june 14, 1976, these facilities were installed and fully operational. the resulting waste-water effluent was tested and found to be totally acc...
