What does the gas-liquid ratio in industrial water treatment refer to

The volume ratio of steam and blow-off object (ammonia-containing wastewater).

Blow-off method for the removal of ammonia nitrogen in water, that is, the gas into the water, so that the gas-liquid mutual full contact, so that the free ammonia dissolved in the water through the gas-liquid interface, to the gas-phase transfer, so as to achieve the purpose of the removal of ammonia nitrogen. Air is commonly used as a carrier (if water vapor is used as a carrier, it is called vapor extraction).

Ammonia blowing off the general use of blowing off the pool and blowing off the tower of two types of equipment, but the blowing off the pool covers an area of large, and easy to cause secondary pollution, so the ammonia blowing off the tower equipment is often used.

Blowing off the tower is often counter-current operation, the tower is equipped with a certain height of packing to increase the gas - liquid mass transfer area in favor of ammonia desorption from the wastewater. Commonly used fillers are Lacy ring, polypropylene Bauer ring, polypropylene multi-faceted hollow ball and so on. Wastewater is lifted to the top of the packed tower, and distributed to the entire surface of the packing, through the packing downstream, and the gas flow in the reverse direction, the partial pressure of ammonia in the air with the degree of ammonia removal increased and increased, with the increase in the gas-liquid ratio and decreased.
