But this process has one problem,"Sudden decreasing of phosphate removal ability ". In relation to this, there is a report that the phosphate removal ability is decreased by an interaction with two kinds of bacterium and between this interaction some kinds of chemical products (by-metabolites) exists. Some kinds of by-metabolites, such as antibiotics, pheromones, and allelochemicals, influences other lifes. The orders of these products are very low but the influences are very high. But from this kind of view, there are no studies on this problem for EBPR process. In this study, there are three objects: 1 To confirm the interaction with two kinds of bacterium 2 To identify some chemical products which is the mediation of this interaction between two kinds of bacterium 3 To clear the system of this interaction I have done the vatch experiment to confirm the interaction with two kinds of bacterium, but I haven't confirmed the interaction with two kinds of bacterium, yet.
