4.3. The contactor

4.3.1.     Batch (CSTR) systems versus fixed-bed contactors 

There are a number of configurations used in engineered systems for bringing a solid sorbent material into contact with a liquid (or gas) stream containing pollutants for removal. The two most common are the continuously-stirred tank reactor (CSTR) (or batch reactor) and the fixed-bed contactor…
