Zusammenfassung:The present invention relates to a bioball including porous polyurethane foam media, and a method and device for treating wastewater using the same. The present invention is characterized by using the porous polyurethane media having ability to stick to microorganisms and bioballs compensating liquidity and abrasion of the media in the use of a bio-membrane reaction process when treating floating materials such as organic materials and nutritive salts in wastewater.
