Abstract
Peroxyformic acid compositions for removal of biofilm growth and other contaminants and impurities from industrial processing hard surfaces are disclosed. In particular, peroxyformic acid compositions may be dosed on site and/or generated in situ for the reduction and prevention of biofilms on the hard surfaces. Methods of employing the peroxyformic acid compositions for removal of biofilm growth and other impurities such as aldehydes and alcohols from industrial CO2 effluent are also disclosed which beneficially provide ambient biofilm control and break down more rapidly than other peracids, allowing for extended runs between CIP cleaning, including a reduction and/or elimination of cleaning of the scrubbers and other industrial surfaces.
