These aids, including aluminum, activated silica, and ferric salts, create a structure with the particles that better traps oxygen. The best ratio for good flocculation is to have the amount of the coagulant or flocculent be 1% -2% of the amount of water (Metcalf & Eddy, ,Wastewater, Engineering, 1972).
