Question: What methods are available for removing sulfur containing compounds from wastewater treatment streams?
Keywords: waste,water,treatment,plant,sulfur,compound,removal,carbon,adsorption,bacterial,bacteria
Answer: Traditionally, substances such as hydrogen sulfide (and other sulfur compounds) are removed from wastewater treatment effulent streams via carbon adsorption. Kobe Steel offers a biological treatment option which has higher capital costs but the operating costs are said to be 1/4 that of carbon adsorption systems. Kobe's system uses sulfur-oxidizing bacteria (Thiobacillus and Hyphomicrobium) on porous 5 mm carbon particles. Operating temperatures are 10 to 30 0C.
