Control of Pollution created by suspended particulate matters (SPM) from small and Medium scale Iron and Steel and Refractory industries - The dry and wet options

Abstract

In the design of pollution control systems, the designer is often faced with the crucial decision to choose between either a dry or a wet system. The choice is not often easy as factors such as cost, availability of process water, implications of causing secondary pollution due to the dis-charge from the scrubbers conflict with each other.Some of these issues have been critically analyzed in this paper with specific examples from pollution control in meta-llurgical industries.
