Control of pollution emitted by foundries

Abstract

Research has made considerable attempt to decrease the emission of harmful gaseous pollutants to the atmosphere. This report reviews hazards due to foundry air pollution, measurement of pollution emission, pollution control devices and policies of pollution control. The pollutants discussed are polycyclic aromatic hydrocarbon, 1-hydroxypyrene, polychlorinated-p-dibenzodioxins and dibenzofurans and polychlorinated biphenyls.

Contemporary and futuristic views of pollution control devices in foundries

“…These authors have not name any foundries situated either within India or outside India which have Implemented ISO 4001 standards based EMS. Availability only this paper in literature arena and absence of report about implementing ISO 4001 standard based EMS give rise to an impressed that enormous amount of practice oriented researchers are required to carried out in the direction of ISO 4001 standard based EMS (European Commission, 2005;Krishnaraj, 2015aKrishnaraj, , 2015bLichtfouse, 2015).…”

“…While both standardized systems (EN ISO 14001:1996 and EMAS) and non-standardized ("customized") systems in principle take the organization as the entity, this document takes a more narrow approach, not including all activities of the organization e.g. with regard to their products and services, due to the fact that the regulated entity under the IPPC (European Commission, 2005;Krishnaraj, 2015aKrishnaraj, , 2015bLichtfouse, 2015).…”

“…This is recognized by the Integrated Pollution Prevention Control (IPPC) Directive definition of 'techniques' as "both the technology used and the way in which the installation is designed, built, maintained, operated and decommissioned". For IPPC installation an environmental Management system (EMS) is a tool that operators can use to address these design, construction, maintenance, operation and decommissioning issues in a systematic, demonstrable way (European Commission, 2005;Krishnaraj, 2015aKrishnaraj, , 2015bLichtfouse, 2015).…”

“…Foundry practices generally involve the melting of metals and pouring the molten metals into cavities called molds (Krishnaraj, 2015b). After solidification, these metals become castings by assuming the shapes of molds.…”

Degradação Bacteriana Da Resina Fenólica Que Constitui Na Aglomeração Da Areia De Fundição

“…A área de fundição tem um papel crucial no crescimento da economia mundial, produzindo lucros para muitos países. Enquanto impacto negativo no ambiente (Beeley 2001), (Krishnaraj 2015), (Penkaitis e Sígolo 2012). Processos de usinas siderúrgicas geram resíduos em várias formas que afetam o ar, a água e o solo; este último é especificamente afetado pela fundição (Siddique, Schutter e Noumowe, 2009).…”
