The global concern about alternative water reuse techniques are increasing continuously as heavy industries such as petrochemicals and agricultures grows bigger each year. Those organic pollutants present in wastewaters which are not treatable by conventional treatment methods, are considered to be treated by stronger and more modern techniques. The presence of these organic compounds in water ...

The aim of this study was to investigate the acute toxicity of pulp-paper industry wastewater using traditional and enrichment toxicity tests and to emphasize the importance of toxicity tests in wastewater discharge regulations. Enrichment toxicity tests are novel applications and give an idea of whether there is potential toxicity or growth-limiting and -stimulating conditions. Different organ...

Background & Aims of the Study: The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants remova...

YORDANOV, D., 2010. Preliminary study of the efficiency of ultrafiltration treatment of poultry slaughterhouse wastewater. Bulg. J. Agric. Sci., 16: 700-704 Poultry slaughterhouses use relatively high amount of water with an average consumption of 26.5 L/bird during primary and secondary processing of live birds to meat. The used water contains proteins, fats, carbohydrates from meat, blood, sk...

The most important necessity for life is water. Shortage of clean & fresh drinking water leads to suffering. This is mainly contributed by generation of sewage waste mixed with the water bodies, due to unplanned urbanization and has largely contributed to the causing severe water pollution. Pollutants discharged in waste waters can be toxic to aquatic life and cause natural waters to be unfit t...

The present investigation provides data on physico-chemical parameters, some major ions and nutrients on water samples of Tinishu Akaki River (TAR), Ethiopia. The pH, temperature, electrical conductivity, total dissolved solids (TDS), dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD), Ca2+, Mg2+, HCO3-, SO42-, NO3-, NO2-, PO43-, Cland NH3 have been determined t...

Paper and pulp industrial waste waters are a major environmental concern. As the treatment of these effluents is a major problem, exploring novel and feasible biotechnological interventions is very important. Utilization of white rot fungi as a means of biological treatment seems to be a viable option. The study was undertaken to use immobilization technique and Phanerochaete chrysosporium, a c...

Textile wastewater contains substantial pollution loads in terms of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and heavy metals. Phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (AMATS) is well established environmental protective technique. A lab scale stud...

In  this  research,  biological  removal  of  phenol  and  orthonitrophenol  (2NP)  pollutants  from wastewater  by  continuous  moving  bed  sequencing  batch  reactor  (MSBR)  was  studied.  The experiments were conducted in various operational conditions to find out the optimum level of the significant  parameters.  Best  performance  for  removal  of  Phenols  was  achieved  when  parameter...
