Manufacturing device and application device for liquid containing micro-nano bubbles

A manufacturing device for liquid containing micro-nano bubbles, comprising:

• a micro-nano bubble generation tank for receiving liquid, including a submerged pump-type micro-nano bubble generator, a non-submerged pump-type micro-nano bubble generator, a bubble level meter for detecting level of bubbles from a fluid level of the received liquid and a turbidimeter for detecting turbidity of the liquid;
• a micro-nano bubble generating aid metering pump for pumping a micro-nano bubble generating aid to the micro-nano bubble generation tank;
• a blower for supplying air to the submerged pump-type micro-nano bubble generator;
• a first control section for controlling the micro-nano bubble generating aid metering pump based on a bubble level detection signal obtained from the bubble level meter so as to control an amount of the micro-nano bubble generating aid introduced into the micro-nano bubble generation tank;
• a second control section for controlling the micro-nano bubble generating aid metering pump based on a turbidity detection signal obtained from the turbidimeter so as to control an amount of the micro-nano bubble generating aid introduced into the micro-nano bubble generation tank;
• a third control section for controlling the blower based on the turbidity detection signal obtained from the turbidimeter so as to control an amount of air supplied to the submerged pump-type micro-nano bubble generator.
