Fresh air through roots blower or Aerator, airway pressure uniform expansion and achieve aerator, large fine bubbles in design value (diameter from 20 ~ 50UM), rise in the extremely slow, dissolved oxygen has obvious effect, thus greatly improve the oxygen in water, increases the breeding density.
Use of new technologies developed by micro-aeration devices for aquaculture Huge advantages.
as a result of the Nano tube the oxygen mass transfer efficiency is very high, so that the unit of dissolved oxygen in water to quickly reach more than 4.5mg/l, less water tankers or impeller oxygen quarter energy consumption can be significant savings in electricity costs of the farmers
|The air flow||-||0.1-0.4m3/h.m||-|
|Average micropore diameter||-||φ0.03~φ0.06mm||-|
|Bubble diameter||-||0.5~2mm (fresh water)
|Effective aeration rate||-||0.002~0.004m3/min.m||-|
|Effective working area||-||1~8m2/m||-|
|Applicable water depth||-||0-5 meters||-|
How to use ?
Make a round ring or square shape elements by iron or steel or plastic pipe as same shape of nano tube, Then the nano tube is tie with plastic tie or rope or thick weir and connect aeration pipe with Nano tube, it is finished by immerse it in water. The pipe must be made in such a way that water enters it. If needed, make some holes above the pipe.
