I previously posted a blog post about a new project for lead removal using a wet electrostatic precipitator (WESP). A Midwestern manufacturer heat treats metal materials in a furnace that generates low concentrations of lead fumes. The fumes are sub-micron in size, making them difficult to remove. The facility is compliant with their existing permit, but wants to be pro-active to control emissions further. They investigated several technologies including HEPA and cartridge filters, Venturi scrubbers, and wet electrostatic precipitators (WESPs). Because of the small particle size, low concentration, and high removal efficiency, they had difficulty finding technologies or vendors willing to guarantee the requested performance limit.
A case study is now available to describe how an Envitech high performance Wet Electrostatic Precipitator solves this problem.
