background and objectives: in the era of global industrialization, enzymes are being used extensively in the various sectors including food processing. owing to the high price of enzymes, various initiatives have been undertaken by the r&d; sector for the development of new processes or improvement in the existing processes for production of cost effective enzymes. with the advancement in the f...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...

the industrial effluents of three textile plants in the south of tehran were studied. in each plant all related factors such as raw material consumption, production processes and water use at different points were examined. these plants discharge their effluents into the environment without any treatment. the common characteristics of these wastes are quantity and quality variability, organic p...

various industrial processes with a huge variety of products, materials and compounds create different kinds of pollution for human beings, so that the identification of environmental pollutants resulting from industrial units’ activities, especially in water resources seems necessary. the aim of this paper is to estimate the role of industrial units in contaminating water resources, through us...

Knowledge management can support industrial research processes. Indeed, these industrial research processes are situated between a system of operational units, requiring and using research results, and a system of technological providers and academic laboratories. The knowledge flow between these systems is exposed to certain industrial constraints. The research center needs to optimize interna...

Li Si, Kong Ruixue, Sun Lin, Li Sifan, Yang Shuangchun* (Liaoning Shihua University. Fushun, Liaoning, China. 113001) Abstract—Industrial wastewater is a kind of wastewater that generate in the industrial production process. The wastewater from refining and coal carbonization contains high concentration of phenols pollutants. In this paper, study on phenol treatment methods in industrial wastew...

The biotechnology industry is not defined by its products, but by the technologies employed in making them. Those technologies involve the use of biological processes to solve problems or to make useful products. Biotechnologies are primarily employed in the medical and pharmaceutical industries, but they are also used to increase crop yields, clean up hazardous waste, and increase the efficien...

magnetite (feo.fe2o3) nanoparticles immobilized on silica and modified by treatment apolaccase were used to decolorize the industrial wastewater from basic red 9 (br9 by way of fenton and fenton-like processes. the surface changes to the silica were determined by scanning electron microscopy, fourier transform infrared spectroscopy, x-ray diffraction and energy-dispersive x-ray spectroscopy. th...

Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran. Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For prelimin...
