System and method for removing scale of sewer pipe using microbial mist type spray

A system for removing scale of a sewer pipe using microbial mist type spray, the system comprising:

• a microbe storage tank configured to store liquid microbes;
• a chamber connected with the microbe storage tank through an injection pipe and supplied with a determined, metered amount of liquid microbes, when needed to spray the metered amount of liquid microbes into the sewer pipe;
• a metering pump provided on one side of the injection pipe, the metering pump configured to supply power for injecting the metered amount of liquid microbes into the chamber;
• a compressed air tank configured to store compressed air;
• a compressed air supply pipe configured to supply compressed air into the chamber when the metered amount of liquid microbes is sprayed;
• a supply tube configured to allow liquid microbes having air cavities resulting from supplying the compressed air to flow;
• and
• a spray nozzle provided at an end of the supply tube configured to spray liquid microbes in a mist-form into the sewer pipe.
