METHOD FOR THE PURIFICATION OF WASTE WATER ABSTRACT OF THE DISCLOSURE Effluent is removed from water by treating the effluent containing water with an enzyme of a microorganism having an aqueous ambience and/or an enzyme of the type employed in detergent preparations. Previous analytic studies of the ambience of aqueous environments have shown the presence of enzymes therein. However, it was heretofore unknown that any of these enzymes could be employed for purifying water. Micro- organisms which have an aqueous ambience are generally a source of the enzymes within the scope of this invention. Preferably, microorganisms whose aqueous ambience is polluted are employed for obtaining the enzymes, and particularly preferred enzymes are derived from microorganisms which thrive in the water which is to be purified. A particularly suitable enzyme is, or instance, obtained from the microorganisms which are employed in conventional activated sludge and trickling filter methods to biologically purify water. Quite unexpectedly it has been found that enzymes produced by these microorganisms, rather than the microorganisms themselves, may be employed to purify effluent containing water. The enzyme producing microorganisms within the scope of this invention are not purestrains; they are mixed populations, such as usually occur in bodies of water, particularly in effluent containing water.
