Acidic wastewater containing Cr from graphite electrolysis
INTRODUCTION OF FGD- SOURCE Wikipedia…

In wet scrubbing systems, the flue ,gas, normally ,passes, first ,through, a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO2-absorber. However, in dry injection or ,spray, drying operations, the SO2 is first reacted with the sorbent, and then the flue ,gas passes through, a particulate control device.

Scrubbers - Bioremediation

A common form is a ,spray tower, - ,gas, flows upward (or horizontally) ,through, successive ,spray, nozzles. ,Spray, towers have very low ,gas, pressure drops & most contacting power is got from the liquid stream (must be apt combination of liquid pressure and flow rate).

Flue-gas desulfurization - en.LinkFang.org

A ,spray tower, is the simplest type of scrubber. It consists of a ,tower, with ,spray, nozzles, which generate the droplets for surface contact. ,Spray, towers are typically used when circulating a slurry (see below). The high speed of a venturi would cause erosion problems, while a packed ,tower, would plug up if it tried to circulate a slurry.

4 Unit operations for producing clean drinking water

Hydrogen sulfide ,gas, turns into hydrosulfuric ,acid, when it dissolves in water. The ,acid, is weak but highly corrosive, eating up electrical contacts, causing a slight odor, and resulting in black water complaints.

Ground Water Surface Water and Leachate

Orifice scrubbers are a group of ,gas,-atomised ,spray, scrubbers where a tube or a duct forms the ,gas,-liquid contacting zone. The particle-laden ,gas, is passed over the surface of a scrubbing liquid at high velocity. The ,gas, stream flowing ,through, the orifice atomises the entrained liquid droplets in the same way as a venturi scrubber.
