According to the present invention, a congelation and coagulation agent comprising quaternary ammonium tannate for water treatment and a method for manufacturing the same reduce waste treatment costs caused by generation of sludge caused by use of an aluminum-based congelation and coagulation agent. The congelation and coagulation agent does not include a metal material and thus can be biologically degraded without concentration of the metal material. Quaternary ammonium tannate improves efficiency for removing suspended solid (SS) or colloid compared to an existing inorganic congelation and coagulation agent and, at the same time, minimizes generation of additional waste treatment costs by reducing a sludge generation amount. In addition, congelation and coagulation agent can be inserted with poly-aluminum chloride, aluminum sulfate, ferric salt such as FeCl_3, polyamine, and poly-DADMAC or functions alone as a congelation and coagulation agent or as a coagulation agent. The congelation ...
