background: industrial development has caused the release of various pollutants including heavy metals into the environment. these toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. the aim of the pre...

With the growth and development of chemical plants, the amount of mercury released in wastewater has increased. Mercury in wastewater contains harmful compounds which are hazardous to the human health and living organisms. Therefore, its removal from wastewater is significant. There are various techniques or methods available for removing mercury from aqueous solutions. This study focused upon ...

Although some studies have investigated the impact caused by chemicals used on water treatment (coagulants and oxidants) cyanobacteria integrity, isolated effect of shear stress during coagulation is still not fully understood. This study evaluated different velocity gradients, mixing times, addition powdered activated carbon (PAC) integrity Microcystis aeruginosa, Raphidiopsis raciborskii, Dol...

The efficiency of solar heterogeneous TiO2 photocatalysis and homogeneous photo-Fenton reaction for removal of Lambda Cyhalothrin, Chlorpyrifos and Diazinon from pesticide wastewater industry was investigated. The effluent quality was not complying for discharge into sewerage network. Therefore, adsorption of the remaining portions of pesticides using powdered activated carbon (PAC) was assesse...

today the industrial wastes are one of the main problems in the developing countries. discharging the industrial wastewater into environment is harmful for human health and other living creatures.thus decreasing of the pollution load of waste waters is an important environmental issue.adsorption of chemical oxygen demand by biomass wastes can be a proper and low cost method for cod removal from...

carbon dioxide is a major greenhouse gas that contributes to the global warming by more than %60. absorption has been widely used to treat high concentrations of co2 in synthesis gas production, hydrogen manufacturing, and natural gas processing. the most well established method to capture co2 is its removal by absorption into amine solutions in the presence of activators. in this research, co2...

Scope of the present study was the comparison of two advanced water treatment technologies – ozonation and powdered activated carbon adsorption (PAC) – with respect to the elimination of emerging contaminants. Main objective was the assessment of synergistic effects arising from the combination of both technologies in one wastewater treatment plant. The study was conducted at a full-scale plant...
