Technology progress is a cause of industrial hazardous wastes increasing in the whole world . Management of hazardous waste is a significant issue due to the imposed risk on environment and human life. This risk can be a result of location of undesirable facilities and also routing hazardous waste. In this paper a biobjective mixed integer programing model for location-routing industrial hazard...

process mediated by or involving microorganisms in which a product of economic value is obtained is called fermentation (Casida, Jr., 1968). The terms industrial microbiology and fermentation are virtually synonymous in their scope, objectives and activities. The microbial product may be microbial cells (living or dead), microbial biomass, and components of microbial cells, intracellular or ext...

industrial waste management is one of the most properly approaches which make industry and environment collaborating and coacting as well as reduce impacts of industry on environment. in this study, present management of yazd industrial township located in yazd province was studied. in order to properly manage and control waste production, questionnaires were used to collect data regarding type...

the purpose of this study was comparison of applicability of tertiary treatment of tehran domestic sewage with organic and inorganic coagulants or a combination of them. the far test procedure was applied utilizing: alum, polyelectrolyte wt 2600, anionic polyelectorlyte wt 3000, and nonionic polyelctrolyte wt 2690 as organic coagulants (products of calgon). the combination of lime with each of ...

Need for an online hazardous waste tracking system Suneel Pandey Hazardous waste management is one of the most challenging aspects of any environmental management system for any industry. There are more than 50 000 chemical substances, with one million combinations, used in industrial activities. Hazardous wastes – in the form of solids, liquids gases or sludge – are generated by a wide range o...

The destruction of toxic organic wastewaters from munitions demilitarization and complex industrial chemical clearly becomes an overwhelming problem if left to conventional treatment processes. Two options, incineration and supercritical water oxidation (SCWO), exist for the complete destruction of toxic organic wastewaters. Incinerator has associated problems such as very high cost and public ...

Fish waste biomasses are locally available resources which contain nutrients. Fermentation of the biomass produces slurries used for plankton production and plant/agri-nutri use. Bio-refinery of fish waste material can be converted into value added biological products such as biofuels, industrial chemicals, animal and fish feed, human food, neutraceuticals and organic fertilizer, etc. Fish proc...

Laboratory scale biological trickling filters and three-phase airlift bioreactors have been studied for the elimination of methylene chloride (or dichloromethane) vapors from waste air, and the results used herein for the design of small industrial-scale reactors. The conditions chosen for scale-up were an air flow rate of 100 m3 h-1, a methylene chloride inlet concentration of 2 g m-3, and a t...

introduction: the development of an appropriate model for the quality control of an industrial wastewater treatment system can save the time as well as the cost. this study was performed to determine an appropriate model in order to predict the cod and tkn parameters by bod5 and nh4+ in the meybod industrial estate waste water treatment plant (wwtp). methods: this descriptive – analytical study...
