The beneficial microbial flocs and the activated inflow water are returned to the storage tank of the water treatment plant.

Generally, the useful microorganism (EM) is a combination of several microorganisms beneficial to humans among many microorganisms existing in nature.

Yeast, lactic acid bacteria and photosynthetic bacteria constitute useful microorganisms, and the antioxidant power of fermentation products (fermentation byproducts) produced by complex coexisting public relations among these microorganisms can be said to be the effect of useful microorganisms.

On the other hand, when the beneficial microbial fermentation by-products exhibit a fulvic acid substrate while maintaining a pH of 3.5 or less as a main ingredient, naturally occurring organic substances (NOM, natrural orgnaic matter) are toxic to aerobic microorganisms when they coexist in the wastewater treatment process It has been reported that it is advantageous to maintain an environment-friendly water treatment process because it has a function to combine and remove odor substances and salts.

In order to maintain such an environmentally-friendly water treatment process, useful microorganisms and byproducts that are proportional to the load of the influent wastewater are required, and water treatment costs are required.

Therefore, a pre-treatment process is required to graft the fermentation process to continuously supply useful microorganisms and fermented products and to ignite the useful microorganisms in the influent wastewater.
