Tube-type fine-bubble aerator | tube fine-bubble aeration
Working Principle
The principle behind the tube-type fine-bubble aerator lies in the tube wall — compressed air enters the inner cavity, then escapes evenly through the fine pores of the wall membrane as large numbers of tiny bubbles. The bubbles spread uniformly along the full length of the tube, creating a large air-water contact area and high oxygen transfer efficiency; as they rise, they also stir the water and keep sludge from settling, delivering steady, even tube fine-bubble aeration.
Application Fields
1.Aerobic biological tanks: even bottom oxygenation through tube fine-bubble aeration.
2.Biological aerated filters : tube-type fine-bubble aerators laid out in rows for bottom oxygen supply.
3.MBBR and MBR: oxygen supply for biofilm and membrane systems, taking advantage of the even air distribution of tube fine-bubble aeration.
4.Industrial wastewater treatment: tube-type fine-bubble aerators covering the aerobic section.
FAQ
Q1: What advantages does a tube-type fine-bubble aerator have over a disc aerator?
A: The tubular design spreads air over a larger area along the tube, so bubbles are distributed evenly across the whole tube, giving fuller coverage and fewer dead zones; it can also be bent and laid out flexibly to fit different tank shapes, making installation easier.
Q2: How are the bubbles produced in a tube-type fine-bubble aerator?
A: Compressed air flows through the distribution piping into the inner cavity of the aeration tube, then escapes evenly through the fine pores of the wall membrane, forming many tiny bubbles. The small pore size makes fine bubbles that create a large air-water contact area and high oxygen transfer efficiency.
Q3: Where is a tube-type fine-bubble aerator mainly used?
A: As a tube-type fine-bubble aerator, it's mainly used for bottom oxygen supply in aerobic biological tanks, biological aerated filters (BAF), MBBR, and MBR processes, and it also works for industrial wastewater biological treatment and aquaculture aeration.
