Waterkeeper is a biocatalyst in a liquid state which is mainly composed of bromeline enzyme and fermentation-suppressed modified yeast. One component, bromeline enzyme, can suppress the growth of corruptive and miscellaneous bacteria predominantly living in the polluted surface water area by its anti-oxidation and anti-bacterium functions. Such bacteria or microorganisms are deactivated, and hence their living area becomes narrow. The other component, fermentation-suppressed modified yeast, a facultative anaerobe, can activate the effective microorganisms, especially available for the decomposition of organic sedimentary sludge. Owing to such a synergism of Waterkeeper, both the purification of water and the decomposition of organic sedimentary sludge can be accomplished simultaneously. Waterkeeper has a distinctive feature to play the part of continual depression of water pollution in the aquatic sphere. The decreases of COD, BOD, T-N and T-P can be accomplished by Waterkeeper’s function that only the effective microorganisms can be activated selectively. The biocatalysis of Waterkeeper activates the effective microorganisms to decompose organic compounds. The negative biocatalysis of Waterkeeper deactivates bacteria leading to putrefaction and contamination, E. coli, etc. The pollutants which are continuously loaded into the aquatic sphere, can be degraded by Waterkeeper’s biocatalysis to recover and guard the ecosystem, because the biocatalysis of Waterkeeper provides the surface water there with the self-cleaning power which is originally possessed by natural living water.
