Rules for operation of dissolved air system

1. The dissolved air system is mainly operated by adding water to the air flotation tank to make the water level of the air flotation machine reach the screw propeller. The water level of the air flotation tank can be controlled by the outlet regulating plate.

2. Close all control valves, turn the electric knob switch to the automatic position, start the water pump, air compressor should also enter the automatic working state, and then open the water pump inlet valve, outlet valve, pressure gauge gradually rose to 4 kg.

3. Open the water outlet control valve of the air floatation dissolution tank, make the mixed water of dissolved air pass through the releaser, release the flocculation mixing section of the air floatation tank, and a large number of micro-bubbles appear in the air floatation tank, which makes the clean water turn Milky white, and the air of the air dissolution system is supplied by the air compressor. As dissolved air and water continuously take away the air in the tank, the air in the tank gradually decreases and the water level rises. When the water level rises to a certain position, the float level gauge will control the work of the air compressor, so that there is enough air in the cylinder.

4. After the dissolved air system operates normally, the sewage after the reaction of adding drugs is sent to the air flotation mixing tank, the quantity is smaller at first, and then increases gradually.

5. Soluble air water first uses tap water as backflow water, and then uses treated clean water as backflow water after normal operation. If there are too many impurities in the reflux water, we can always use clean water.

6. Air-floated truss slag scraper should be operated for a long time to avoid too much suspended matter affecting the effluent effect.www.khnwatertreatment.com
