Abstract
The present invention provides a process for the treatment of sewage sludge with enzymes, which process comprises treating a sewage sludge resulting from the treatment of municipal or industrial waste water with a composition comprising a fermentation supernatant product from a Saccharomyces cerevisiae culture and a non-ionic surfactant, wherein said fermentation supernatant product is free of active enzymes, at conditions suitable for generating said active enzymes from said sewage sludge in situ.
Claims20
A method for treating a contaminated water, the method comprising the step of:
- adding a bio-catalytic composition to the contaminated water, the bio-catalytic composition comprises a fermentation supernatant from a yeast culture containing no active enzymes and one or more nonionic surfactants, the fermentation supernatant including bio-nutrients, minerals and amino acids,
- wherein addition of the bio-catalytic composition to the contaminated water forms a plurality of microbubbles having a reactive membrane barrier that enhances oxygen or other gas transfer across the reactive membrane barrier.
