Full Description

To determine water quality effects on groundwater treatment for hydrogen sulfide, the authors compared sulfuric acid (H2SO4) and carbonic acid for pH adjustment pretreatment in a pilot-scale (40-gpm [2.5-L/s]) randomly oriented packed tower. Pretreatment with either H2SO4 or carbon dioxide (CO2) to pH 6.0 resulted in
