Specifications

Advantages:
*Flexible replacement for upgrading projects
*Multi installation for PVC,HDPE,Steel,etc.
*High oxygen transfer

Fine Bubble Disc

aerators for fish

 

Structure:

 

1.Membrane:Adopted the EPDM/Silicone  to melt. It can restrain the ageing effectively of the membrane, and protract the using life over 8 years.

 

2.Slit Hole :Adopted the "^" shaped for perforating to prevent adverse of waste water effectively and the bubble would be less than 0.3nn during aeration.

 

3.Base :Made by PP+FIBER GLASS , well resistance to corrosion and service long life.

 

Advantages:

 *Flexible replacement for upgrading projects

*Multi installation for PVC,HDPE,Steel,etc.

*High oxygen transfer effciency 

*Intermittent operation capability 

*High resistance to corrosion 

*Back flow prevention

*Quick installation and low maintenance

*Low pressure loss

*Water-stirring effect

 

 

 

Application:

 

Biological treatment
