Positive Organisms in Process Water Systems
... In order to control the microflora in the process water a 100 fold of positive microorganisms in spore form are added to the water. The principle is to outcompete negative organisms in a ratio of 100 good ones to 1bad one. Concurrently, a number of experiments were set up whereby several parameters ...
