Working Principle
High-speed-working impellers splash the water into the air- these splashing water mix the oxygen in the air and be brought into the water--and dissolved oxygen in the water increase.
The woking impellers produce waves and currents-- make the saturated ammounia, CO2, methance, sulfuredted hydrogen,etc. go out of the water--the water quality improved.
