Background: one of the most important environmental pollutants is industrial wastewaters. Discharging of colorful industrial effluents to receptive waters can lead to eutrification and it has the carcinogenic and mutagenic properties. Therefore, the aim of this study is evaluation of Acid blue 15 dye removal by dried Azolla from aqueous solution. Material and methods: The Azolla biomass was dri...

2,4,7,9-Tetramethyl-5-decyne-4,7-diol (TMDD) is a non-ionic surfactant which is preferentially used as defoamer in paints and printing ink and for the treatment of surfaces. Effluents of wastewater treatment plants (WWTPs) have been identified as the domination point sources for TMDD in rivers since the removal rate of the compound in the WWTPs is in general less than 70%. However, the dominati...

* E-mail: [email protected] ABSTRACT Effluents of textile dyeing are characterized by intense colour, chemical oxygen demand, suspended solids and a variety of refractory matter, such as heavy metals and nonionic surfactants. Strong colours may reduce light penetration, thus affecting the growth of plants and having impact on invertebrate and other forms of wildlife. There are a large numbe...

Development of an environmental friendly and cost-effective process for microbial degradation of caffeine to non-toxic compounds are promising to solve the problems of physiochemical extraction of caffeine in the treatment the caffeine containing agro-industrial effluents. Thirteen bacterial strains, isolated from tea plantation soils in the north region of Iran, were screened to show their abi...

Rapid population growth resulting in industrial proliferation and urbanization has led to the rapid increase pollution of environment. Paint industries urban areas mostly channel their wastewater into streams on land, which results receiving This study aims determine impact effluent discharges from paint soils’ physicochemical properties clean-up polluted soil through monitored natural attenuat...

the continuous addition of industrial, municipal, and agricultural effluents to the environment has led to a great increase of toxic pollutants. it is well known that these pollutants are hazardous to animals, plants, microorganisms, and other living organisms including humans. as a result, effective technologies should be developed to remove these contaminants. biological remediation, as an...
