How to make the dissolved air flotation run smoothly?

In order to make the air flotation machine run smoothly, according to the flocculation situation of the reaction tank, the scum and the water quality of the effluent in the reaction zone, attention should be paid to adjusting the parameters such as the dosage of coagulant, especially to prevent the blockage of the dosing pipe. And regularly check the water level indicator tube of the dissolved air tank, and control it within the range to ensure the effect of dissolved air, and avoid the water level of the dissolved air tank causing a large amount of air to enter the air flotation tank due to the emptying of the air tank, which will damage the water purification effect and scum layer.
Those who have been equipped with an automatic liquid level control device for the dissolved air tank should pay attention to the maintenance of the equipment, regularly check the oil filling and lubrication systems of the air compressor of the air flotation machine and the water pump, and refuel frequently. When the water temperature is too low in winter, the flocculation effect is poor. In addition to generally increasing the dosage, sometimes it is necessary to increase the amount of dissolved air or the pressure of dissolved air to make more flocs adhere to the micro-bubbles to compensate for the increase in water flow viscosity. The impact on the floating performance of flocs ensures that the water quality of the effluent is normal.
In the air flotation device, there is a part called the air flotation tank, which is a circular steel structure, which is the main body and core of the sewage treatment machine. Pool, mud scraper system, etc. In the middle position of the air flotation machine, the releaser is the key component for making microbubbles.
The water outlets are arranged at the lower part of the tank and connected to the upper part of the tank through a vertical main pipe. The water outlet is equipped with a water level adjustment handle to facilitate the adjustment of the water level in the tank. The mud pipe is installed at the bottom of the tank to discharge the mud deposited on the bottom of the tank. The mud tank is located on the upper part of the tank and is equipped with a scraper. The scraper rotates continuously to continuously scrape the floating mud into the mud tank, and then the Outflow from the pool.
