This invention discloses a cooling tower circulating water optimization control system and method, relating to the field of cooling tower control technology. The invention includes, in response to a bypass filter start command, controlling a bypass filter pump to start at a first frequency and continue operating for a preset delay. During this preset delay, the water output from the bypass filter pump is directed to the drain pipe.
