Oxygenator which kind of effect is good?

At present, there are impeller oxygenator, water truck oxygenator, bottom microporous oxygenator (Roots fan oxygenator).

1, stirring the water body, the water truck oxygenator is better.

2, the water depth of 1 meter - 1.5 meters, oxygen demand is not high, the breeding of four large fish, the use of impeller oxygenator can be.

3, if the nursery pool, hatchery, water depth of about 0.5 meters, the choice of Roots fan bottom micro-porous oxygenator, the effect is better,

4, water depth of 1.5-3 meters or more than 3 meters, aquaculture of white shrimp, crabs, sea cucumbers and so on, the need for upper and lower water circulation, dissolved oxygen is high, you can choose to use the Roots fan bottom micro-porous oxygenator, or supporting the use of the water truck! Oxygenator, the best results!

If you choose the Roots fan bottom microporous oxygenator. Available aquaculture oxygen selection formula estimate, inlet volumetric flow Qs = pond water volume X1.5% or more (m?/h), so that according to the fish pond situation to calculate the required flow to the fish pond depth of water to determine the pressure of the Roots fan, 1 meter water depth is equal to 9.8 KPA, 2 meters water depth is equal to 19.6 KPA, and so on, will be the parameter consulting manufacturers, you can determine the flow of Roots fans parameters and number of units.
