摘要:
The present invention relates to a method for the prevention of microbial growth in process waters. The method comprises adding aluminium ions into process water prior to or with the addition of a peracid or a mixture of peracids to maintain soluble aluminium concentration in the process water on the level of at least 0.05 ppm. The addition of aluminium ions enhances the biocidal performance of peracid or a mixture of peracids in the process water.
