How to extend the service life of air floatation equipment

To ensure that the life of air floatation equipment is longer, we must pay attention to the flocculation of the reaction tank, the scum and air quality of the air flotation area, pay attention to the adjustment of the amount of coagulant dosage and other parameters, in particular, to prevent drug addition. Blocked pipe. After that, pay attention to regularly check the air compressor and air pump filling and lubrication system, often refueling.

 

Check the water level indicator tube of this dissolved gas tank frequently to control it within a certain range (generally within 60-100 cm). At this time, the effect of the dissolved gas can be ensured, and the water level of the dissolved gas tank can be prevented from being emptied, resulting in a large amount of air entering the air floating tank and destroying the water purification effect and the scum layer. For the automatic control device that has already been installed with the dissolved gas tank level, it is necessary to pay attention to the maintenance of the air floatation equipment.

 

In periods of low water temperature in winter, due to the poor flocculation effect, in addition to the need to increase the dosage, it is sometimes necessary to increase the amount of dissolved air or dissolved air pressure, so that more microbubbles adhere to the floccule to compensate for the increased viscosity of the water flow. Influencing the floating performance of the air-entraining floccule so as to ensure the normal quality of the effluent, so that the service life of the air flotation machine can also be prolonged.

 

When the air floatation equipment is in use, it is necessary to pay attention to the situation of the air flotation tank surface. If it is found that the scum surface of the contact area is uneven, large bubbles appear in the area or the water flow is unstable, it is necessary to pay attention to remove the release device to remove the blockage; If the scum surface of the separation zone is uneven and there are often big bubbles on the surface of the pool, it indicates that the air bubbles and floccules do not adhere well. It should be checked and the coagulation system should be adjusted or appropriate measures should be taken (such as adding surfactants, etc.). ) to protect the equipment.

 

When the air floatation equipment is in use, the unqualified effluent returns to the catchment and the qualified effluent enters the subsequent treatment system. After that, we must pay attention to the daily operation record of the air flotation machine, mainly including the treatment of water volume, dosage, dissolved air volume, dissolved gas tank pressure and so on. These aspects have noticed that it will also be possible to extend the life of air floes.
