A method for determining an optimal dose of coagulant for raw water includes a step of determining a value, for the raw water, of a first organic parameter; a step of determining a value, for the raw water, of a second mineral parameter; a step of determining a class of water for the raw water, characterized by the value of the first organic parameter and the value of the second mineral parameter; a step of determining a value, for the raw water, of a third organic parameter; a step of defining a target value, for the clarified water, of the third organic parameter; a step of selecting a function between the third organic parameter and an added dose of coagulant, said function being selected for the class of water and for the value, for the raw water, of the third organic parameter; a step of using the function to determine a first dose of coagulant in order to reach the target value.
